Shopify Sidekick Checkout (2026): Blocks & Accounts

Updated October 15, 2026. Editorial note: Vervecta is an independent educational website, not Shopify. This guide is based on Shopify’s published documentation, including its October 13, 2026 Sidekick update. Screens, labels, feature access, and plan entitlements can change. We have not performed a live checkout deployment for a merchant account; illustrative examples and suggested prompts are not measured business outcomes.

If you want to customize your Shopify checkout with Sidekick, start with the distinction that matters most: Sidekick helps you understand and plan changes; you still make, save, test, and publish those changes yourself. Shopify introduced Sidekick guidance directly inside its desktop checkout and accounts editor and its Checkout Blocks app in October 2026. For store owners, that means fewer documentation searches and clearer next steps—but not an autonomous checkout designer.

This step-by-step guide explains exactly where to open Sidekick, how to use it to plan checkout and customer-account changes, which Checkout Blocks features are available on Basic versus Plus, and how to test everything before customers encounter it. You will also get copy-ready prompts, practical configuration examples, a permissions checklist, and troubleshooting advice.

Quick answer: In Shopify Admin, go to Settings → Checkout → Configurations → Edit. On a desktop computer, open Sidekick in the checkout and accounts editor. Ask for help with a specific setting or app. Then make the approved changes manually in the editor or the Checkout Blocks app, click Save, preview desktop and mobile views, and run an appropriate real-world checkout test. Shopify explicitly states that Sidekick cannot edit, save, or publish these configurations for you.

Before you change anything: Confirm your Shopify plan, check staff permissions, document your current checkout, and make a duplicate draft configuration when appropriate. Payment, tax, shipping and customer-data handling are business-critical; do not use unverified AI suggestions as a substitute for legal, technical, or payment-provider requirements.

What Is Shopify Sidekick Checkout Customization in 2026?

Shopify Sidekick is Shopify’s built-in AI assistant. The October 13, 2026 update added context-sensitive guidance in two important places: the checkout and accounts editor, and the Checkout Blocks app. Instead of asking a general chatbot how Shopify works, you can ask a question while working in the relevant interface.

What Shopify Sidekick Checkout Can Help You Do

In the checkout and accounts editor, Sidekick can explain settings, walk through tasks, recommend suitable apps, and search the Shopify Help Center. In Checkout Blocks, it can explain how blocks and functions work, review saved configurations, describe display rules, and point you to settings you should adjust yourself.

This is especially useful if you are unsure whether your requested change belongs to Shopify’s built-in settings, an app block, a Shopify Function, or a plan-dependent checkout feature. A good Sidekick prompt states your desired customer experience, where it should appear, and your subscription plan.

What Sidekick Cannot Do for Your Checkout

Sidekick cannot edit, save, or publish the checkout and accounts configuration on your behalf. It reads saved settings, not pending unsaved edits. It is available in the checkout and accounts editor on desktop, not as the same embedded editor feature on mobile. A suggestion to add a custom field is not proof that your plan supports that custom field.

Do not confuse three separate actions: asking Sidekick for instructions, configuring the feature in Shopify, and testing whether that feature actually works for customers. Each requires its own verification.

Sidekick, Checkout Blocks, and Customer Accounts Are Different Tools

Component	Primary job	What the merchant controls
Shopify Sidekick	Explain settings and guide the setup	Prompts, interpretation and every final change
Checkout and accounts editor	Configure eligible checkout and account pages	Branding, sections, blocks, page layout and saving
Checkout Blocks	Provide supported content blocks and checkout functions	Block creation, placement, display rules and availability
Customer accounts	Let shoppers access orders, account details and related features	Supported pages, account settings and installed app experiences

Think of Sidekick as a knowledgeable assistant inside the workflow—not the payment processor, a substitute for the editor, or a guarantee of higher conversion rates.

Shopify Checkout Customization: Basic vs Plus Plan Limits

Plan eligibility comes before configuration. Many articles about checkout customization imply that any merchant can add custom fields to the payment page. That is misleading. Shopify’s documentation draws a clear boundary between standard checkout/account customization and advanced checkout-page extensions.

Shopify Basic, Grow, and Advanced: What Is Available?

Merchants on Basic or higher have access to the checkout and accounts editor, standard branding options, supported customer-account extensions, and eligible app blocks on the Thank you and Order status pages. In Checkout Blocks specifically, static content and dynamic content blocks can be used on those two post-purchase pages.

These plans do not get the same Checkout Blocks custom fields, shipping/payment method functions, or blocks inserted into information, shipping, and payment stages as Plus. You can still improve clarity with permitted settings, accurate product content, shipping information and relevant post-purchase messages.

Shopify Plus: Advanced Checkout Blocks and Functions

Shopify Plus permits a wider range of checkout extensibility. Depending on the supported block and configuration, Plus merchants can add eligible blocks to checkout, use custom fields, manage certain delivery/payment presentation rules, and implement advanced validation or discount behavior. The exact pages supported depend on the specific block—not simply on the merchant’s plan.

For example, a custom field captures information before an order is placed, so it cannot be meaningfully placed on the Thank you page. Some content blocks can appear before or after purchase, subject to plan restrictions. Shopify’s official block reference should be your final eligibility check.

Compare Plans Before You Follow a Tutorial

Desired customization	Basic / Grow / Advanced	Plus
Logo, colors, typography in supported checkout branding	Yes	Yes
Checkout and accounts editor	Yes	Yes
Static or dynamic Checkout Blocks content on Thank you / Order status	Yes	Yes
Eligible customer-account app features	Yes, depending on app	Yes, depending on app
Checkout Blocks custom field in the checkout itself	No	Supported, subject to block rules
Checkout Blocks payment or delivery method functions	No	Supported
Checkout-stage app UI extensions	Generally Plus-only	Supported
Sidekick guidance in desktop checkout editor	Use if available in your editor	Use if available in your editor

Practical decision: If you are not on Plus, do not spend hours searching for a pre-payment custom-field switch that your plan does not support. Start with settings available in your plan, or evaluate whether a Plus upgrade has a justifiable return.

Prerequisites Before You Open Shopify Sidekick Checkout

Make the first session a controlled change-management exercise rather than a spontaneous redesign. Checkout errors can disrupt orders, so prepare your environment before opening the editor.

Check Account Permissions and Your Current Plan

Confirm your store’s subscription level and whether your staff account has permission to access Checkout settings, manage apps, and edit the required content. Shopify’s Checkout Blocks documentation notes that staff may need permission for metaobject definitions and entries as well as access to the app itself. If a button is missing, insufficient permissions may be the cause rather than an app error.

If you work with an agency, give access only to people who need it. Avoid sharing owner credentials; use Shopify’s supported user and collaborator permissions.

Document Your Current Checkout and Account Experience

Record your store’s current configuration name, active payment methods, shipping options, taxes, visible policies, and customer-account pages. Take reference screenshots on mobile and desktop and note any tracking pixels or installed checkout apps. Export a simple checklist of what must remain unchanged.

This baseline makes troubleshooting easier: if a new message overlaps a payment option, you will know what changed. For substantial layout work, Shopify recommends duplicating a checkout configuration to create a draft version before editing.

Define One Measurable Goal

Possible goals include reducing ambiguity around dispatch times, making return instructions clearer after purchase, reducing unnecessary input fields, or simplifying payment-method presentation. Each goal requires a different location and likely a different plan capability.

For example, “help customers find tracking information on their Order status page” is specific and often suitable for permitted post-purchase blocks. “add a mandatory gift-message field before card payment” is a different requirement that can depend on Plus functionality.

Step-by-Step: Open Shopify Sidekick in the Checkout Editor

The verified path is Shopify Admin → Settings → Checkout → Configurations → Edit. Shopify’s editor contains Sections, Settings, and Apps sidebars. A page selector lets you preview Checkout, Thank you, Order status, Orders, Profile and Sign-in pages, depending on your configuration and checkout layout.

Step 1: Open Shopify Checkout Settings on Desktop

Sign in to the correct store on a desktop browser. Select Settings, then Checkout. Find Configurations, and choose Edit next to the checkout configuration you intend to review. If multiple configurations exist, confirm which one is active and whether you are inspecting a draft.

Do not assume changing the theme editor changes checkout: these are separate workspaces. Some shared brand settings can carry over, but a theme section is not the same as a checkout app block.

Step 2: Launch Shopify Sidekick Checkout Guidance

In the checkout and accounts editor’s menu bar, click the Sidekick icon. If you cannot see it, confirm you are inside the supported desktop editor—not your storefront, your mobile theme editor, or the general WordPress-style content editor of another platform.

Start with a narrowly scoped question: “On my current plan, which supported method can display delivery guidance on the Order status page?” A useful response should identify where to navigate, not assert that a change was already made.

Step 3: Ask About the Saved Configuration

Sidekick reads the settings that have been saved. If you just changed a setting and want Sidekick to explain the new state, save it first. If you have not yet reviewed the impact of a risky change, avoid saving directly to an active configuration merely to obtain AI feedback; work in a draft where the platform provides that option.

Ask Sidekick: “Which blocks and apps are currently configured for this checkout? Explain each one and identify any settings I should verify.” Compare its explanation with the actual settings visible in the editor.

Step 4: Make the Changes Yourself and Save

Use the editor’s Sections, Settings, and Apps sidebars to configure supported elements. Depending on the type of feature, you may first need to set up a block in Checkout Blocks, then return to the editor and place it on a supported page. Sidekick will not perform those actions automatically.

After reviewing the preview and required permissions, click Save. Check whether a separate publishing or activation action applies to the draft configuration you edited. Never assume a saved draft is the same as a live configuration.

Step 5: Preview Desktop, Mobile, and Shop Pay

Use the editor’s page selector to inspect Checkout, Thank you, Order status and relevant account pages. Shopify provides a mobile preview, and, if Shop Pay is enabled, a Preview Shop Pay option. The editor itself is a simulated environment: its payment buttons cannot replace real purchase testing.

Check text length, translated labels, line wrapping, price visibility, errors, and focus order. A message that looks good on a wide screen can crowd a narrow mobile checkout.

Step 6: Test a Safe Order Flow Before Going Live

Follow Shopify’s supported test-order process for your payment setup. Validate expected shipping and tax calculations, permitted payment methods, confirmation emails, tracking links and post-purchase content. Record what passed, who approved the change, and what would trigger a rollback.

Do not use genuine customer payment details as test data. Avoid placing live paid orders merely to check a banner when a preview or an authorized test gateway is sufficient.

Install and Configure Shopify Checkout Blocks

Checkout Blocks is a Shopify app for supported content blocks and checkout functions. Installation alone does not place an element in the checkout: the merchant usually needs to configure the block and add it in the checkout and accounts editor. The app’s feature set is broad, but much of it is Plus-only.

Step 1: Install the Official Checkout Blocks App

Find Shopify’s official Checkout Blocks app in the Shopify App Store. Review its developer, permissions and feature availability, then install it for the intended store. The official documentation provides an installation link and states the relevant staff-permission requirements.

Once installed, use Apps → Checkout Blocks in Shopify Admin. If you cannot open the app, verify installation and app-specific permissions before reinstalling.

Step 2: Choose the Right Checkout Block Type

Start with a supported use case. Static content displays a consistent message to visitors. Dynamic content can display messages based on configured rules. Other blocks can capture fields, show line-item details or support validation, but their page and plan eligibility vary.

For a Basic store, a clear post-purchase customer support message on the Thank you page may be useful. For Plus, a checkout custom field or conditional delivery message may be appropriate. Avoid creating an extra field merely because the option exists: ask whether the data is truly needed to fulfill the order.

Step 3: Configure, Place, and Review the Block

Some block types are configured in Checkout Blocks before being added via the checkout editor. Others, including certain static content, can be created directly in the editor. In Settings → Checkout → Configurations → Edit, open the Apps sidebar, add the relevant supported block to the relevant page, and inspect display rules and preview behavior.

Read the block’s supported-page documentation carefully. A pre-checkout custom field cannot be relocated to the Order status page and still capture pre-payment consent.

Step 4: Use Sidekick to Explain Rules Before You Activate Them

Inside Checkout Blocks, ask Sidekick: “Explain why this block is configured this way, which customers will see it, and what could prevent it from appearing.” Shopify’s October 2026 change specifically mentions assistance with blocks, functions, saved configurations and instructions.

Then inspect the actual conditions yourself: market, cart content, shipping country, customer state and page placement can affect display. If you cannot verify a rule, use a simpler unconditional message first rather than activating complex logic in a live checkout.

Step 5: Validate Block Visibility and Analytics

Test the page with representative scenarios: mobile, desktop, international destination, different cart totals and eligible customer profiles. Shopify’s Checkout Blocks app provides Views analytics for active blocks; these indicate displays, not necessarily clicks or conversions. Treat a view count as a diagnostic signal rather than proof that the customization made more money.

Check the date range when reading block statistics. Compare behavior and support contacts over time, and do not attribute revenue changes to a block without a sound experiment.

Customize the Thank You and Order Status Pages Without Plus

The most accessible opportunities for Basic-plan merchants are often after purchase. A shopper who has just paid needs reassurance: when will the parcel dispatch, how can they track it, and where can they get help? A useful post-purchase page answers these questions without interrupting payment.

Example: Add a Helpful Order Status Message

Suppose your store ships within two business days and sends tracking details when the carrier accepts the parcel. Write a short message that matches your actual policy, such as: “We will email tracking details when your order ships. Check this page for the latest status, or contact our support team if you need assistance.”

On a supported plan, use a static content block where eligible on the Order status page. Preview it on mobile. Do not promise that every parcel arrives within two days when the two-day target only covers processing.

Example: Use Conditional Post-Purchase Guidance

If your plan and block support it, dynamic content can display different guidance based on rules. A domestic order might show local shipping support information, while an international order could link to customs and estimated-delivery guidance. Ask Sidekick to explain the supported display conditions, but verify them in the actual block configuration.

Never expose sensitive customer details in publicly shareable messages or links. A post-purchase page is not a safe place to display internal fraud scores, private staff notes or unrestricted customer records.

Thank You vs Order Status: Choose the Right Destination

The Thank you page is shown after purchase. The Order status page remains available for customers to check an existing order. Content that matters for ongoing tracking generally belongs on the latter. A one-time post-purchase message can work on the former.

If you want buyers to find return information days later, consider linking to a clearly maintained return policy and providing account navigation rather than relying solely on a message they saw once. Review page links in your own checkout experience.

Use Shopify Sidekick for Customer Accounts Customization

Customer accounts are more than a sign-in button. They include pages for orders, order status, profile data and sign-in, with additional extensions possible depending on an app and your store’s setup. The same checkout and accounts editor is used to preview and configure supported pages.

From the editor’s top page selector, navigate to the customer-account pages relevant to your business. Review the Orders page for understandable order history, the Profile page for customer details, the Sign-in page for clarity, and the Order status page for tracking and assistance. Customer account features and installed blocks differ across stores.

Ask Sidekick to explain available app options for the specific page: “I want shoppers to find previous orders easily. What built-in customer account navigation exists, and when would an app be necessary?” Follow the supported options, rather than trying to redesign account authentication with unsupported checkout HTML.

Add Customer Account Apps Only When They Solve a Real Problem

Shopify allows eligible apps to add account experiences. You might need a loyalty interface, a returns portal, or a self-service subscription view. Before installing, compare data access requirements, ongoing fees, compatibility and customer support. More blocks are not automatically a better account experience.

Keep access and data minimization in mind. If an app requires broad customer records for a simple tracking link, consider whether a narrower tool or built-in setting can solve the problem.

Sidekick Customer Accounts Prompt: A Realistic Example

Try: “In my current customer accounts configuration, help me identify how buyers navigate from Order status to Orders and Profile. Explain supported apps if I need a clearer support link, and list which steps I must save myself.”

That prompt explicitly requests an explanation, not autonomous account changes. After following the instructions, sign in as a permitted test customer and verify the customer-facing result. Do not rely entirely on the editor preview when the task involves authentication.

Payment and Shipping Customization: What Is Actually Safe?

Payment and shipping are not cosmetic details. Hiding a method can change completion rates and accessibility, and a mismatched shipping rule can cause operational losses. Use Sidekick to understand Shopify’s supported workflow—not to invent financial or regulatory rules.

Shopify Sidekick Checkout Prompts for Shipping Methods

If you are on Plus and have the appropriate Checkout Blocks functions, you may be able to reorder, rename or conditionally hide supported delivery choices. A practical prompt is: “I want to make standard delivery clearer for domestic shoppers without hiding legitimate express shipping methods. What settings and Plus-only functions should I review?”

Test with different addresses and cart profiles. Make sure that renamed options still communicate real carrier, cost and speed conditions. Do not label a shipping choice “free” unless the price and eligibility rules actually make it free.

Payment Method Changes Need Extra Review

Similarly, checkout payment customizations powered by supported functions are largely Plus-only in Checkout Blocks. Discuss the business logic with finance and payments teams before hiding or reordering options. Verify whether a method is required for your target market and whether accelerated checkout behaves differently.

Never ask Sidekick to remove required authentication steps, defeat fraud prevention, or bypass payment-provider policies. Always test Shop Pay and other enabled express experiences independently.

Avoid False Trust Signals and Unsupported Claims

Trust badges or “secure checkout” copy should not suggest certifications the merchant does not hold. A visible payment icon is not proof that a particular payment method is available to every customer. A guaranteed-delivery claim needs actual operational support.

For meaningful checkout improvements, accurate taxes, a clear delivery promise, readable policies and a functioning payment flow matter more than decorative badges. Use measured customer feedback rather than copying a competitor’s UI blindly.

18 Copy-Ready Shopify Sidekick Checkout Prompts

The most useful prompts identify where, what, which plan, and how to verify. Replace brackets with your real configuration; do not paste sensitive customer information into an AI prompt unnecessarily.

Discovery and Plan Eligibility Prompts

Plan check: “My Shopify plan is [plan]. Which checkout and accounts editor changes are available to me, and which require Plus? Link the relevant Help Center pages.”
Inventory: “Explain the saved apps and blocks in my current checkout configuration. Which are customer-visible and which only change settings?”
Navigation: “Show the steps to open the Order status page in the checkout and accounts editor and tell me where I would save changes.”
App selection: “Suggest criteria for evaluating apps that display post-purchase support links. Prioritize privacy, plan compatibility and minimal cost.”
Risk assessment: “Which of my proposed changes could affect payment, shipping price, taxes or checkout completion? Give me a pre-launch checklist.”
Desktop limitation: “If I cannot find the embedded Sidekick panel on mobile, what is the supported desktop path to access it?”

Checkout Blocks and Post-Purchase Prompts

Thank you copy: “Draft a concise Thank you page message based only on this verified dispatch policy: [policy]. Avoid making delivery guarantees.”
Order status: “Guide me through adding a static content block on the Order status page using Checkout Blocks on [plan].”
Conditional content: “Explain whether a dynamic content block can display different approved support text by market, and how I can validate the rule.”
Custom fields: “Do I need Shopify Plus to collect [specific field] during checkout? Which block can do it and what alternatives exist for my plan?”
Block diagnosis: “This block is configured but not visible. Help me check page placement, display rules, active state and plan requirements.”
Analytics: “Explain what the block’s Views metric means and what it does not prove about orders or conversion.”

Customer Accounts, Testing, and Compliance Prompts

Account journey: “Help me map the customer path from sign-in to Orders, Profile and Order status without changing authentication.”
Mobile review: “Give me a mobile checkout QA checklist for long text, keyboard usability, accessibility and payment choices.”
Shop Pay: “Tell me how to preview Shop Pay in the editor and what else requires actual test-order validation.”
Localization: “My store serves [countries]. Which checkout text, currency and market assumptions should I verify before localizing messages?”
Approval log: “Create a short change log template showing purpose, affected pages, plan requirements, reviewer, tests and rollback instructions.”
Saved changes: “I changed [setting]. Explain how I can verify the saved configuration and distinguish a draft from the active live checkout.”

Prompt-writing tip: Request specific navigation and limitations, not unsupported commands such as “redesign my entire payment checkout and publish it.” Sidekick’s ability to answer a question does not grant app permissions, increase plan access, or perform the change.

Shopify Checkout Conversion Optimization: What to Measure

The phrase “increase conversions” is frequently used without measurement. A new message can reduce support tickets even if it has no observable effect on checkout conversion. Establish a baseline and select metrics aligned with the change’s purpose.

Start With a Simple Measurement Plan

For payment-flow changes, monitor checkout completion and failed payment patterns using available Shopify analytics and payment logs. For post-purchase instructions, monitor related customer-support contacts and satisfaction signals. For customer accounts, look at task completion and unnecessary support requests, if your analytics and privacy settings allow it.

Example: if the specific goal is reducing “Where is my order?” contacts, track the weekly number of such contacts per 100 orders before and after improving Order status messaging. This is an illustrative measurement method, not a claim that Checkout Blocks will reduce tickets.

Separate Block Views From Revenue Uplift

Checkout Blocks’ Views statistics show how often a configured block appears. They do not demonstrate that the block caused more sales. A rise in views may be driven by higher overall traffic, a different product mix or seasonal marketing.

If you test a checkout change, use a supported experimental approach and consult a qualified analyst when sample sizes are small. For a related merchant guide, see Vervecta’s Shopify Rollouts tutorial, which covers planned launches and A/B testing concepts. Do not assume an app-block change can always be A/B tested in every plan.

Watch for International Checkout Edge Cases

Test representative countries, currencies and shipping zones. A message saying “Free delivery over $50” may be incorrect if the threshold is calculated differently for another market or if a product is excluded. Check tax-inclusive versus tax-exclusive price displays where relevant.

Markets-specific customization options can require higher Shopify plans, and a localized message might not follow a user as you expect. Use the editor’s market preview where supported and verify actual rules for each destination.

Seven Practical Checkout Scenarios by Store Type

Use these as planning patterns, not as claims that Shopify supports every option on every plan. Each scenario includes its likely page, constraint and validation step.

Scenario 1: Small Store Needs Order Tracking Help

Goal: Reduce confusion after purchase. Approach: A Basic merchant adds an eligible static Order status message with a verified help link and accurate dispatch wording. Validation: Place an authorized test order and check the tracking journey on mobile. Constraint: Do not treat a message as automated tracking integration.

Scenario 2: Apparel Store Wants a Gift-Message Field

Goal: Capture a gift note before the purchase. Approach: Evaluate a checkout custom field if the store is on Plus and the supported block fits the requirement. For a non-Plus store, consider a separate supported product-page or cart workflow if suitable. Validation: Confirm the information travels to the order record as intended. Constraint: A post-purchase field cannot retroactively capture a pre-payment choice.

Scenario 3: International Merchant Needs Clear Customs Guidance

Goal: Reduce surprise about duties and delivery. Approach: Explain customs information in approved policy pages and, where suitable, add a post-purchase link to the relevant information. Validation: Compare two shipping destinations and the actual duties/tax setup. Constraint: Do not promise duties are included unless the store’s pricing and delivery terms make that true.

Scenario 4: Subscription Brand Wants an Account Help Entry

Goal: Let customers locate subscription support. Approach: Use a supported customer-account app or account navigation experience, not an unsupported checkout script. Validation: Sign in with a test account, inspect permissions, and verify the support route. Constraint: A subscription app’s billing permissions deserve additional review.

Scenario 5: B2B Seller Needs Purchase-Order Details

Goal: Capture information required by procurement. Approach: Confirm whether the checkout plan and supported extension can provide an appropriate field, or use established B2B workflows. Validation: Test business customers, invoices and fulfillment data. Constraint: Do not store sensitive identifiers without a lawful purpose and access controls.

Scenario 6: Plus Merchant Wants Delivery Methods Reordered

Goal: Make legitimate delivery choices easier to compare. Approach: Evaluate Checkout Blocks’ supported shipping and payment functions in Plus. Validation: Test a broad set of shipping zones, products and accelerated checkouts. Constraint: Reordering must not remove a method unexpectedly or misrepresent delivery times.

Scenario 7: Holiday Sale Needs a Checkout Readiness Audit

Goal: Avoid disruption during a promotion. Approach: Review current checkout settings with Sidekick, verify discount eligibility and test post-purchase messages before the campaign starts. Validation: Use test orders across price tiers and promotional conditions. Constraint: A marketing promotion should not change checkout functions unless a separate business requirement justifies it.

Read Vervecta’s Shopify Campaign Autopilot guide for campaign planning and our Shopify SimGym guide for simulated storefront design feedback. Those tools solve different problems from checkout configuration and should not be presented as replacements for payment testing.

Troubleshooting: 12 Common Shopify Sidekick Checkout Problems

Troubleshoot in order: correct store → plan → page → permissions → saved configuration → block rules → customer-facing test. Reinstalling an app before checking these basics can create duplicate configuration work.

1. Sidekick Is Missing From the Checkout Editor

Make sure you are on a desktop computer inside Settings → Checkout → Configurations → Edit, not the online-store theme editor. Check that the store and current staff role can access the checkout editor. Shopify’s embedded Sidekick feature is documented for the desktop editor. If your account still lacks the control, consult Shopify’s current availability documentation or support rather than assuming a universal outage.

2. Sidekick Describes Old Settings

Save relevant changes before asking Sidekick to interpret them. Shopify says Sidekick reads saved configurations. An unsaved block, font choice or app rule may not appear in its description. If necessary, reopen the relevant configuration and compare Sidekick’s explanation with the editor’s visible values.

3. Sidekick Gives Instructions but Does Not Make Changes

This is expected behavior. Sidekick provides guidance, not direct edit/save/publish authority for the checkout and accounts editor. Follow its navigation instructions manually, review every setting and click Save. Record which configuration you updated and whether it is active or a draft.

4. Checkout Blocks Features Are Locked

Check your subscription. Basic, Grow and Advanced merchants have limited Checkout Blocks content on Thank you and Order status pages. Checkout-stage custom fields and payment/delivery functions generally require Plus. An unavailable button is not necessarily a bug or a reason to install unofficial extensions.

5. A Block Was Created but Never Appears

Verify that you configured the block, added it to a supported page in the checkout and accounts editor, saved the configuration, and enabled any required conditions. Some block types need both app-side setup and editor placement. Also check whether the active checkout configuration is the one you edited.

6. Dynamic Content Shows to the Wrong Customers

Inspect the block’s conditional display rules and test representative combinations of country, cart, shipping option and customer status. Ensure rule descriptions match the logic actually saved. Simplify conditions until you can explain why a test shopper did or did not see the block.

7. A Custom Field Cannot Be Added to Thank You

Some fields must capture information before the order completes; Shopify’s block reference explains that these cannot be placed on a post-purchase page. Use an appropriate checkout-stage extension only when your plan supports it, or redesign the workflow to collect optional information elsewhere without breaking fulfillment.

8. Payment or Delivery Rules Do Not Work

Payment and delivery customizations in Checkout Blocks are Plus-only, and their rules can interact with zones, order conditions, payment availability or express checkout. Review the saved function configuration, confirm its scope, and test actual eligible scenarios before deployment. Do not disable important payment choices merely to make the display look simpler.

9. The Mobile Preview Looks Broken

Switch to mobile preview, shorten headings, remove redundant copy and check that app blocks do not crowd buttons or overlap order totals. Test tap areas and keyboard navigation where possible. When an issue affects an installed app block, contact the developer with the page, device, configuration and reproduction steps.

10. Shop Pay Preview and Standard Checkout Differ

If Shop Pay is enabled, use its dedicated preview in the editor. Some UI and flow behavior can differ from the standard checkout. Verify the actual checkout journey with Shopify-supported test methods, especially when a change involves shipping, payment visibility or account state.

11. Checkout Blocks Says Permission Denied

Review app access and staff permissions. Shopify documents metaobject permissions and Checkout Blocks app permissions as requirements for staff members. Ask a store administrator to grant only the missing capability, rather than exchanging account passwords or granting full owner access unnecessarily.

12. A Checkout Change Was Saved but Is Not Live

Determine whether you edited a draft or the active checkout configuration. A saved draft is not automatically a published live experience. Check the configuration management options, required activation steps and storefront result. If the active flow is affected, follow your rollback plan and investigate before making additional changes.

Shopify Sidekick Checkout: Frequently Asked Questions

Can Sidekick customize my Shopify checkout automatically?

No. In the checkout and accounts editor, Sidekick explains settings and provides guidance. Shopify states it cannot edit, save or publish a configuration for you. You make and approve those changes in the supported editor or app.

Where can I find Sidekick in Shopify checkout settings?

On a desktop computer, open Shopify Admin → Settings → Checkout → Configurations → Edit and click the Sidekick icon in the editor’s menu bar. Availability and interface labels should be checked in your own store.

Is Shopify Sidekick checkout help available on mobile?

Shopify documents the embedded Sidekick feature in the checkout and accounts editor as desktop-only. The editor itself includes mobile preview options, but that is different from using embedded Sidekick on a mobile device.

Can Shopify Sidekick save checkout changes?

No. You need to adjust the setting and click Save yourself. Sidekick only reads saved settings, so it may not recognize new edits until they are saved.

Is Checkout Blocks free to install?

Shopify’s Checkout Blocks is presented as a free app, but specific feature access depends on your Shopify subscription and supported pages. Other checkout apps can have their own fees. Always confirm current pricing before approving an installation.

Does Shopify Basic support checkout blocks?

Yes, in a limited way: Checkout Blocks static and dynamic content blocks can be used on Thank you and Order status pages. Its advanced checkout-stage features are generally reserved for Plus.

Do I need Shopify Plus to add custom checkout fields?

For the Checkout Blocks custom field feature within checkout, Shopify Plus is required. A different supported workflow might capture noncritical information before checkout, but do not assume that every third-party app bypasses Shopify’s plan restrictions.

Can I customize shipping and payment methods with Sidekick?

Sidekick can explain the settings and available solutions. Actually reordering, renaming or hiding supported delivery/payment methods through Checkout Blocks functions is a Plus capability, and the merchant must configure and test it.

How can I add a delivery note to the Thank You page?

On an eligible plan, use an appropriate static or dynamic content block on Thank you, and ensure the wording matches your real fulfillment policy. Save the configuration and test the page. A message does not alter the carrier’s delivery schedule.

Can Sidekick work with customer accounts?

Yes. Shopify’s update extends Sidekick guidance to the checkout and accounts editor, including help understanding customer-account settings and app options. It does not independently alter account permissions, sign-in, or orders.

Does Checkout Blocks increase conversion rates?

There is no universal guarantee. Blocks may improve clarity or reduce friction when thoughtfully used, but they can also add clutter. Measure the outcome that matters and distinguish block views from conversion improvement.

Can I insert a block into the payment page on a Basic plan?

Not using the advanced checkout UI extensions restricted to Plus. Merchants on Basic and higher have more limited post-purchase app customization; verify each block’s eligible page and plan.

Does saving a checkout draft publish it?

Not necessarily. Check whether you edited the active configuration or a draft and follow Shopify’s configuration-management steps. A preview and a saved configuration are not equivalent to a verified live checkout.

Can I test payments inside the checkout editor?

The checkout editor is a simulated environment and disables actions such as completing real payments. Use Shopify’s supported test-order methods appropriate for the store and payment gateway to verify actual transaction behavior.

How do I see analytics for a Checkout Blocks block?

Open the active block’s details and review its Views analytics, including the selected date range. The metric counts block displays; it does not directly report attributed sales or prove that the block caused a conversion.

What should I do if Sidekick suggests something my plan cannot use?

Check Shopify’s official documentation and your current plan entitlements. Ask Sidekick for a supported alternative or revise the requirement. Do not assume an AI suggestion changes your plan permissions.

Can I add scripts directly to checkout like older tutorials show?

Avoid outdated checkout.liquid and additional-script instructions. Shopify has moved checkout and post-purchase customization toward supported checkout extensibility, app blocks and web pixels. Consult current migration guidance before modifying an older integration.

What is the best first Sidekick checkout improvement?

Choose the smallest change with a clear customer benefit: accurate branding, a useful Order status support message, or clearer post-purchase guidance. Confirm plan eligibility, preview mobile, save deliberately and test. Only introduce advanced Plus features when the operational need is justified.

These address different parts of the customer journey; none replaces supported checkout implementation and testing.

Final Verdict: Use Shopify Sidekick as a Guided Checkout Assistant

The strongest 2026 use case for Shopify Sidekick checkout customization is guided implementation. Sidekick helps you understand your saved setup and locate relevant controls. The checkout and accounts editor is where you inspect and save supported changes. Checkout Blocks provides specific UI and function capabilities, subject to strict plan and page constraints.

Start with a single measurable customer problem, choose the smallest eligible change, use Sidekick for explanation, then validate the live experience yourself. For a Basic merchant, well-written Thank you and Order status content may be the practical first improvement. For Plus, more powerful checkout-stage blocks and functions create additional options—but also call for more rigorous testing.

The goal is not more blocks. It is a clearer, reliable and trustworthy path from checkout to customer support.
