Shop identifies customers "before purchase"
Faster checkout, with carts synced across devices

Shop can now recognize customers while they're still browsing your store. Shop users get faster checkout, carts synced across devices, one-tap sign-in, and a prefilled Shop Pay button, while their browsing history and abandoned carts are synced to their Shop account and shown to them again later.

1What's changing

The point at which Shop can identify a customer has movedfrom "at purchase" up to "while browsing the store".
As a result, Shop users get a "fast, synced, prefilled" experience even before they reach checkout.
?

Before: while browsing, the customer is unknown

The only comparison this article makes explicit is that customers can now be identified before purchase. Identifying them during browsing is the new behavior.

Now: Shop identifies customers while they browse

Checkout loads faster, carts sync across devices, sign-in takes one tap, and the Shop Pay button is prefilled. Browsing activity also syncs to the customer's Shop account.

2How it works: from browsing to purchase and recovery

Shop user Browsing the store Your store At the browsing stage, before purchase Shop recognizes the customer Shop To their account Sync browsing and carts What Shop users get ① Faster checkout loading ② Carts synced across devices ③ One-tap sign-in ④ Prefilled Shop Pay button Shop resurfaces viewed products and abandoned carts
The key is when identification happens. Because the customer is already known while browsing,Ready before customers even reach checkout, and even after they leave, Shop canbring them back with reminders. In the article's words, it's how you "close the conversion loop."

65 key points for developers

1. Identification moves earlier, to while customers are browsing

This is the core of the update. Faster checkout, syncing, prefilling, and recovery all follow from Shop being able to recognize the customer before purchase.

2. Cart state can change outside your store

Carts sync across devices and in both directions between the Shop app and the storefront. If your implementation assumes it owns the cart state, keep in mind that the cart can be updated externally.

3. The Shop Pay button is personalized

It shows the card the customer used most recently. Assume the button looks different for each customer, and test the UI in your theme accordingly.

4. One-tap applies to customer account sign-in

It applies when Shop users sign in to a customer account. For stores with a member login flow, this changes the login experience.

5. Setup, API specs, and measurement are not stated

The Changelog only describes the customer experience. It does not cover enablement steps, eligibility, the Storefront API / Admin API, Webhooks, or how to measure revenue from recovered carts.Supported on all browsersis all it states. If you're working on implementation or measurement, verify with the Help Center and on real devices.

73 practical use cases for your business

Desktop ⇄ Mobile
USE CASE 1

Recovering lost sales for considered purchases where shoppers browse on mobile and buy on desktop

Challenge
For considered purchases like furniture, electronics, and apparel, shoppers add items to their cart on mobile during their commute, but when they later open the store on desktop the cart is empty, and they drop off.
Approach
Since carts now sync across devices for Shop users, position Shop Pay as the primary checkout path.
Impact
Shoppers no longer have to rebuild their cart when switching devices, so there's less friction on the way to purchase.
Tech notes
Design around the fact that syncing applies only to Shop users. Behavior for non-Shop users isn't documented.
USE CASE 2

Revisiting cart abandonment tactics: adding Shop's built-in recovery

Challenge
You run your own abandoned cart emails, but had no way to reach shoppers who left before you captured their email address (before reaching checkout).
Approach
Treat Shop's built-in feature, which identifies customers while they browse and resurfaces or sends reminders about viewed products and abandoned carts, as one more channel alongside your existing cart abandonment tactics.
Impact
You can reach Shop users who leave before checkout, making it easier to close the conversion loop.
Tech notes
How to control frequency and overlap between Shop's reminders and your own emails isn't documented. Monitor it in practice so the customer experience doesn't become excessive.
CVR / Time to checkout
USE CASE 3

Shortening the checkout path for stores with a high share of repeat customers

Challenge
Many customers buy regularly, but they have to sign in and choose a card every time, so checkout takes too many steps.
Approach
Promote one-tap sign-in for Shop users and the Shop Pay button showing their last-used card as the primary path.
Impact
Fewer steps for sign-in and payment entry, plus faster checkout loading.
Tech notes
Compare checkout completion rate and time to checkout before and after rollout to confirm the impact. How to isolate whether a session came through Shop isn't documented.
