Shopify checkout customization, built and tested in your store.

Yes, within limits set by your plan. Stores on the Basic plan or higher can change the logo, colors and fonts in Shopify's checkout editor and add app blocks to the Thank you and Order status pages. Adding your own blocks, fields or offers inside the information, shipping and payment steps needs Shopify Plus. Direct edits to checkout code are no longer possible on any plan.

Go to Settings, then Checkout, in your Shopify admin and edit a checkout configuration. The editor sets your logo, color palette, font, and button and accent colors. Since February 5, 2026 Shopify no longer lets you add a background image to the header or main content area. Finer control, such as corner radius on form fields, needs the Checkout Branding API, which is Shopify Plus only.

It is Shopify's name for customizing checkout through apps and extensions that plug into set places, in place of editing checkout code. It covers checkout UI extensions for what shoppers see, Shopify Functions for the rules behind checkout, web pixels for tracking, and branding settings. Shopify's developer docs now also call it Shopify Extensions in Checkout.

Shopify Functions are small programs that run on Shopify's servers during checkout and change its rules. One can create a new kind of discount, hide or rename a shipping option, reorder payment methods, or stop an order that breaks a rule you set. Each is installed as part of an app. They replaced Shopify Scripts, which stopped running on June 30, 2026.

Yes, with a checkout UI extension, which needs Shopify Plus for fields inside checkout. Shopify's own example is a delivery instructions field under the shipping options. Baymard counts 23.48 form elements in the average US checkout against 12 to 14 in a well-built one, so we add a field only when you need the answer to fulfil the order.

Yes. An upsell is an offer to add one more product to an order. Inside checkout, an offer block needs Shopify Plus. After payment, a post-purchase page can show an offer before the Thank you page, and App Store apps for it work on Basic and higher. Shopify skips that page when a shopper pays with a wallet such as Apple Pay or Google Pay.

Yes. Shopify Functions can hide, reorder and rename delivery options and payment methods, based on things like the cart total or the shipping destination. Two limits catch people out. Outside Shopify Plus, stores in the United States and Canada cannot change credit card fields this way. On any plan, wallets shown by logo, such as Shop Pay and Apple Pay, cannot be renamed.

Baymard Institute asked US online shoppers why they abandoned a cart, leaving out those who were only browsing. Extra costs such as shipping, tax and fees came first at 40%. Slow delivery was 20%, not trusting the site with card details 19%, being made to create an account 18%, and a checkout that was too long or complicated 17%.

Partly. Basic and higher plans get the checkout editor, app blocks on the Thank you and Order status pages, web pixels for tracking, and App Store apps built on Shopify Functions. Without Plus you cannot place app blocks inside the information, shipping and payment steps, install a custom-built app that contains Functions, or use the Checkout Branding API.

Shopify sets hard limits that keep them light. A compiled checkout UI extension cannot be larger than 64 KB, and Shopify's help center says Functions execute in under 5 milliseconds. The bigger risk is stacking apps. Shopify allows up to three app blocks in one area of checkout, so we check what is already installed before adding anything.

checkout.liquid was a theme file that let Shopify Plus stores edit the code of their checkout pages. Deprecated means Shopify has retired it. Its customizations stopped working on the information, shipping and payment steps on August 13, 2024, and on the Thank you and Order status pages on August 28, 2025 (both as listed on 5 Oct 2026).

No. Shopify's help center says that as of June 30, 2026 Shopify Scripts has been deprecated, and any Scripts still published have been deactivated and no longer work. Scripts were small pieces of Ruby code that changed discounts, shipping options and payment options. Each one has to be rebuilt as a Shopify Function. Your admin keeps a Scripts customizations report listing what was active.

Additional scripts are not supported on the new Thank you and Order status pages. Tracking now runs through web pixels, Shopify's replacement for pasted tracking code. Shopify warns that you may see fewer events after the switch, because pixels only track shoppers who have given consent. We rebuild each tag as a pixel, then check event counts against real orders.

Start with an app. If a well-reviewed App Store app does what you need, it is usually the faster route, and on a non-Plus store it is the only route for shipping, payment and discount rules. A custom extension makes sense when your rule is specific to your business, when apps overlap, or when you want to own the code.

It depends on the route. A checkout editor setting costs nothing beyond your plan, and an App Store app costs whatever the app charges. For custom work, Shopify developers in the US and Canada typically charge $120 to $200 an hour, according to CartCoders' 2026 rate guide. In-checkout extensions also need Shopify Plus, which Shopify lists at $2,300 a month on a three-year term. FactoryJet quotes a fixed price in writing after a short scoping call.

A single change, such as one field or one shipping rule, is a small job, and the timeline goes in writing with the quote. Moving a store off several Scripts or a heavily edited checkout.liquid is a project. Our focused Shopify Plus builds covering checkout, Functions or a migration usually run 5 to 8 weeks.

In a draft. Shopify lets a store keep draft checkout configurations beside the live one, so we build there first. The editor preview cannot place orders, so we also place test orders in a development store with payments in test mode, covering both layouts, Shop Pay and phones. Publishing the draft turns the old live configuration into a draft, which gives you a way back.

No. FactoryJet is a registered Shopify Partner, without a Plus Partner tier. We do the engineering work itself: checkout UI extensions, Shopify Functions, checkout branding, and the rebuilds that follow checkout.liquid and Scripts. If your procurement team requires a Plus Partner badge, tell us on the first call.
