One-Click Checkout: How To Add It to Your Store (2026)

One-click checkout lets a shopper buy an item with a single click, using the payment details and shipping address their payment provider already has on file. It’s also called “one-click pay,” “one-click ordering,” or “one-click purchase,” and it’s the technology behind the fast checkout buttons on many storefronts.

Baymard Institute puts the average documented cart abandonment rate at about 70%. Two reasons this happens at checkout: 18% of US online shoppers have abandoned an order because the site required them to create an account. Meanwhile, 17% left a cart behind because they hit a long or complicated checkout process. One-click checkout can reduce the amount of information shoppers need to enter at checkout.

This guide covers what one-click checkout is, how it works, and how it can affect your conversion rate and your repeat purchases. It also goes over when it’s the wrong fit for your products and how to turn it on in your Shopify admin.

What is one-click checkout?

One-click checkout is a checkout process that lets a recognized shopper complete a purchase without re-entering payment and shipping information. Customers give their name, email address, billing information, and shipping location once to a payment processor or digital wallet, which stores it for future purchases. Some services, including Shop Pay, can recognize shoppers across participating stores. 

By comparison, a standard checkout experience may require the shopper to enter payment and shipping details on a separate screen for every purchase they make.

“One click” describes the shopper’s experience, not the underlying transaction. Behind that single click, the processor still authorizes the card, applies the shipping address, and passes the order to your store. What changes is the number of checkout pages the shopper sees.

S’wheat, a UK reusable bottle brand, offers one-click checkout on their ecommerce store using Shopify’s Shop Pay. A returning shopper who reaches the cart finds the payment and shipping information already filled in, leaving one button to complete the order.

How does one-click checkout work?

One-click checkout works by storing a shopper’s payment and shipping information with a payment processor, then recognizing that shopper on a return visit and reusing the stored details. Three things happen in sequence:

1. First purchase. The shopper enters their payment details, billing address, and delivery address at checkout and opts in to saving them. The payment processor keeps the record, not your store.
2. Recognition. On a later visit, the payment processor identifies the shopper and loads their saved information. Depending on the provider, the shopper may authenticate through a one-time code, password, fingerprint, or face scan. 
3. Single click. The shopper confirms. One click sends the order to your store and completes the purchase.

Step one is where the security question sits. What the processor keeps is a token rather than a usable card number: tokenization swaps the sensitive payment data for a non-sensitive stand-in (or “token”). The token can be used to process authorized transactions without exposing the underlying card number.

The stored payment information behind that token sits on systems subject to the Payment Card Industry Data Security Standard (PCI DSS), the card networks’ shared rules for handling cardholder data. 

What are the benefits of one-click checkout?

• Higher conversion rates
• A faster checkout process
• Easier repeat purchases
• More mobile purchases

Removing form fields between the cart and the confirmation page touches four measures at once: how many browsers become paying customers, how quickly they move through the buying process, how many return, and how many convert on mobile devices. More sales is the aggregate; the four sections below cover each measure separately, along with the conversion and cart abandonment data behind it.

Higher conversion rates

FragranceNet.com, an online fragrance retailer selling more than 40,000 SKUs, added Shop Pay to their custom platform and saw a 3.4% increase in conversion rates plus 7.5% growth in new customer acquisition within a month.

The second figure covers first-time buyers. Shopify measured the lift by comparing transactions from new customers with Shop Pay enabled against a control group.

“We are now able to not only provide a better experience to existing customers, but also attract those who were not shopping with us before,” says Michael Nadboy, chief marketing officer at FragranceNet.com. “To be able to do both, that’s really what the objective is.”

An external study by a Big Three global management consulting firm found that Shop Pay lifts conversion by up to 50% compared with guest checkout and outpaces other accelerated checkouts by at least 10%. Even unused, the presence of Shop Pay increases lower-funnel conversion by 5%.

A faster checkout process

For recognized shoppers, one-click checkout can remove the need to re-enter information such as your email address, shipping address, and payment details. Aviator Nation, a California apparel brand running 17 retail stores on Shopify POS alongside their online store, now sees 70% of customers check out with Shop Pay.

“When you’re not having to put in your email address, you’re not having to re-input your shipping address, the impact that has across conversion when you’re processing hundreds of thousands of transactions a year is really meaningful,” says Curtis Ulrich, director of ecommerce at Aviator Nation. “And we’ve seen that impact across the entire business, whether it’s the digital side or the retail side.”

Easier repeat purchases

Repeat customers can reuse the same stored payment and shipping information on every order after their first, so the setup cost lands once. One-click checkout gives repeat buyers the same recognition a customer account provides, but without the account creation step.

Shop Pay extends that recognition beyond a single website. Shoppers who save their details at one store are recognized at every other store on the network, and their orders surface in the Shop app, which puts products in front of more than 150 million shoppers.

Customer loyalty programs sit alongside this rather than replacing it. A one-click checkout doesn’t build a relationship on its own; it removes the identity step between a returning shopper and a repeat purchase experience.

More mobile purchases

Mobile carries most of the traffic and most of the losses. Averaging Dynamic Yield’s monthly benchmarks, drawn from more than 200 million monthly users, across the first half of 2026 splits by device like this:

Mobile shoppers put items in the cart more often than desktop shoppers do, then leave those carts behind 10 percentage points more often. The weak point gives merchants a reason to examine the mobile experience between add to cart and purchase, including checkout.

The checkout form is the part a store owner can change. One-click payments can reduce mobile form entry to simplify impulse purchases as well as planned ones.

Is one-click checkout right for your products?

Two numbers in your own reports answer this. Your returning customer rate and your average order value can help you evaluate whether one-click checkout is likely to be useful. A high returning customer rate means more of your traffic already has payment information stored with a processor, while average order value gives you context on the size of the purchases moving through checkout.

Product type and return policies can also influence how a merchant uses a shorter checkout process. Sylvia Fountaine, CEO and founder of recipe blog Feasting at Home and kitchen goods store Bowl and Pitcher, says the relatively low cost of her products makes impulse purchases compatible with the store’s return policy. 

“Since we sell smaller items like spices, pottery, and kitchen wares, it makes sense to encourage impulse purchases while tempering one-click checkout with a generous return policy,” says Sylvia. “We carry small inventory and sell mostly local goods, so there is usually a demand for returned, non-edible items like pottery and books.”

Neither number is a threshold. Together they tell you how much of your traffic a one-click checkout would reach, which is the baseline for any customer satisfaction or conversion test you run afterward.

Not every catalog benefits. One-click checkout is a weaker fit when:

• You sell specialized hardware, machinery, or configured equipment
• Your buyers are businesses working through a purchasing process with approvals
• Your orders need sizing, fitting, or a consultation before they’re placed
• Your average order value is high enough that a review step is standard in your category
• Your returns are expensive to process, and instantaneous ordering leaves no room to reconsider

None of these rule out offering one-click checkout as one option among several. They mean it shouldn’t be the only path through your checkout pages.

What are the best one-click checkout options?

• Shop Pay
• Instant Checkout
• Link by Stripe
• PayPal
• Apple Pay and Google Pay
• Meta Pay

Each option below either recognizes a returning shopper and fills in their details, or shortens the path from product page to checkout. A store can offer several at once. In Shopify, they appear together in the Express Checkout section at the top of checkout, ordered dynamically so the fastest accelerated checkout for that shopper shows first.

Shop Pay

Shop Pay is Shopify’s one-click checkout, available free to any store using Shopify Payments. It saves, encrypts, and autofills checkout fields across every store on the network, so a shopper who has bought from any Shop Pay store can reuse their saved Shop Pay information when checking out from your store, even if they haven’t purchased from you before.

Businesses on a custom or non-Shopify platform can add it without replatforming. FragranceNet.com took that route, integrating Shop Pay as a modular Shop Component in eight weeks with no operational disruption.

Turning on Shop Pay also gives you a buy now, pay later (BNPL) payment option through Shop Pay Installments. Eligible US merchants can also activate Shopify Protect to cover qualifying Shop Pay transactions against fraud-based chargebacks.

Pricing: Free for stores on Shopify Payments.

Instant Checkout

Shopify includes a Buy It Now button you can switch on from your theme settings at no cost, which sends a shopper from a product page straight to checkout. Stores that want more control over how that button looks and behaves can add the Instant Checkout ‑ Buy button app, which has Built for Shopify status.

The app adds a customizable, sticky Buy Now button to product, collection, and homepages, plus click analytics on how often it’s used. Compare that click data against your cart-page conversion before deciding whether to keep it.

Pricing: $4 per month, with a three-day free trial.

Link by Stripe

Link is Stripe’s saved-payment feature, and it works on stores running Stripe. Shoppers store a debit card or credit card details in their own Stripe account once, then check out in a single click at any site offering Link.

Stores can accept Stripe payments on Shopify as an additional payment method. Link then appears as a one-click option for shoppers who’ve used it before.

Pricing: Stripe’s standard US rate is 2.9% plus 30¢ per successful card charge.

PayPal

PayPal reported 439 million active accounts in their first-quarter 2026 results.

Shoppers who’ve saved their billing and shipping information with PayPal skip the login and complete the purchase from the checkout page. Set up PayPal from the payments section of your Shopify admin.

Pricing: PayPal Checkout costs 3.49% plus 49¢ for US domestic transactions, as of July 15, 2026 (the most recent update). Standard credit and debit card payments cost 2.99% plus 49¢.

Apple Pay and Google Pay

Apple Pay and Google Pay turn the card a shopper already keeps on their phone into a one-click checkout, with no separate account for them to create. Both are accelerated checkout methods you activate from your Shopify admin. On mobile devices, the shopper authenticates with a fingerprint or face scan instead of typing anything.

Neither charges you directly. The card payment still runs through your processor at your usual rate, so the cost of adding them is setup time rather than a fee.

Pricing: Free to activate. Standard card processing rates apply.

Meta Pay

Meta Pay, formerly Facebook Pay, is no longer an accelerated checkout option for Shopify stores. Meta has wound down the partner program that lets other online stores integrate it. The wallet now works inside Meta’s own apps: Facebook, Instagram, WhatsApp, and Messenger. Shoppers can still store and encrypt card information in Meta Pay and use it there.

For a store, this means Meta Pay belongs in your social selling plan. Sales that start on Meta’s apps can finish on your own website, where your one-click checkout options do the work.

Pricing: Free to shoppers. Payment processors charge their standard rates on card payments.

How to implement one-click checkout for your store

You can implement accelerated checkout on Shopify without writing code, because it’s already built in. Shop Pay comes with every Shopify Payments account at no extra cost, so there’s no custom integration to commission and no separate one-click checkout provider to contract with. Turning on Shop Pay is a setting:

1. From your Shopify admin, go to Settings, then Payments.
2. In the Shopify Payments section, click Manage.
3. In the Shop Pay section, check Shop Pay.
4. Click Save.

Add the other digital wallet options from the same screen. The Wallets section of your Shopify Payments settings covers Apple Pay, Google Pay, and Amazon Pay, and the Additional payment methods section covers providers such as PayPal. To let shoppers skip the cart, turn on dynamic checkout buttons in your theme editor so an accelerated checkout button appears on product pages.

If you’re building a new store or considering a move, Shopify supports one-click checkout natively through Shop Pay, Apple Pay, Google Pay, and PayPal. Compare ecommerce checkout flow capability and cart abandonment tooling, not on storefront features alone.

Once the buttons are live, test a purchase on a phone and on a desktop browser, confirming the express checkout row appears above the payment form and that product pages carry a Buy it now button.

Once you’ve collected enough post-launch data, review payment methods to see which accelerated checkout options your customers use most, then compare your conversion rate and cart abandonment against the month before, segmented by device.
