If you've ever watched a customer add a product to their cart and then disappear before completing their purchase, you already understand the cost of friction. Cart abandonment sits at roughly 70% across ecommerce, and a significant slice of those lost sales comes down to one thing: too many steps between wanting a product and paying for it. Express checkout exists to close that gap, giving shoppers a single-tap path from intent to purchase. For Shopify merchants, getting this right isn't a nice-to-have — it's a direct lever on revenue.
The challenge is that enabling express checkout on Shopify involves more than flipping a switch. You need to understand which payment methods to activate, where to position the buttons, how your theme interacts with accelerated checkouts, and what to test once everything is live. Many merchants enable the feature once, assume it's working, and leave significant money on the table through poor placement or missed configuration steps.
This guide walks you through exactly what Shopify express checkout is, how to enable it correctly, and how to optimise it for real performance gains. Whether you're running a fashion store, a subscription brand, a B2B catalogue, or a food business, the principles here apply — and the results, when implemented well, are measurable within days.
What Is Shopify Express Checkout and Why Does It Matter?
Express checkout refers to the accelerated payment buttons that allow customers to complete a purchase in one or two taps, bypassing the traditional multi-step cart and checkout flow. On Shopify, these buttons are powered by Shop Pay, PayPal, Google Pay, and Apple Pay, all of which can be enabled directly through your payment settings. Rather than asking a customer to enter their email, shipping address, and card details manually, express checkout pulls pre-saved information from their device or account and completes the transaction almost instantly.
The commercial case for express checkout is strong. Shop Pay, Shopify's own accelerated checkout, has been shown to increase conversion rates by up to 50% compared to guest checkout in some merchant studies. The reason isn't magic — it's that returning customers who have shopped anywhere using Shop Pay before have their details already saved, meaning the checkout experience is genuinely frictionless. For mobile shoppers in particular, who make up over 60% of ecommerce traffic for many stores, eliminating form-filling has a dramatic effect on whether they complete the purchase.
For merchants supplying busy professional buyers — procurement teams, events teams, or hospitality operators who purchase repeatedly — express checkout also reduces the cognitive load of repeat ordering. When someone from a large organisation needs to reorder quickly, a one-tap checkout removes every possible excuse to delay. That speed advantage compounds over time, turning one-off buyers into habitual customers.
How to Enable Express Checkout in Shopify: Step by Step
Enabling express checkout in Shopify starts in your Payments settings, found under Settings > Payments in your Shopify admin. Your first priority is activating Shop Pay, which is available to all merchants using Shopify Payments. If you're in a market where Shopify Payments isn't available, you can still enable PayPal Express, which operates through a separate integration but delivers a similar accelerated experience for PayPal account holders.
Once Shop Pay is active, navigate to Settings > Checkout and look for the Checkout customisation section. Here you can toggle which express checkout buttons appear on your product pages and cart page. Shopify allows you to display these buttons independently on product pages — meaning a customer can bypass the cart entirely — or restrict them to the cart and checkout pages only. For most merchants, enabling them on product pages delivers the highest uplift, but if your products require customisation or upselling, you may prefer to route customers through the cart first.
For Apple Pay and Google Pay, activation happens through the same Payments settings, but you'll need to ensure your store is served over HTTPS (all Shopify stores are by default) and that your theme supports dynamic checkout buttons. If you're using an older theme or a heavily customised layout, check your theme's documentation or test in a staging environment before going live, as rendering issues can cause the buttons to appear broken or misaligned.
Choosing the Right Express Checkout Methods for Your Customers
Not every express checkout method is equally relevant to every merchant's audience. Apple Pay skews toward iOS users and tends to perform strongest for premium or lifestyle brands whose customers are more likely to be iPhone users. Google Pay covers Android users and desktop Chrome browsers, making it a strong default addition for any store with a broad demographic. PayPal Express remains relevant for older demographics and international buyers who may not have a Shop Pay account but have used PayPal for years.
Shop Pay is generally the highest-converting option for Shopify merchants because it's deeply integrated into the platform and can autofill not just payment details but also shipping preferences and discount codes. If a customer has used Shop Pay at any of the millions of Shopify stores globally, their information is available the moment they check out on yours. This network effect makes Shop Pay meaningfully different from the other options and worth prioritising in your button layout and any marketing copy you use to describe your checkout.
The practical advice here is to enable all four methods and then use your analytics to see which your customers actually use. Shopify's built-in analytics will show you completed orders by payment method. After 30 days of data, you can make an informed decision about which methods to highlight or promote. Don't make assumptions about your audience before seeing real behaviour — merchants are often surprised by which method their customers prefer.
Optimising Button Placement and Visual Hierarchy
Where you place your express checkout buttons matters as much as which ones you activate. Shopify's default theme behaviour places the dynamic checkout buttons directly below the Add to Cart button on product pages, which is the correct position for most stores. However, if your theme has a long product page with extensive descriptions, reviews, and cross-sell sections, consider whether the button is visible above the fold on mobile without scrolling. If it isn't, you're losing customers who never see the option.
On the cart page, express checkout buttons should appear prominently above the standard checkout button, not buried below it. Some merchants mistakenly treat express options as secondary, when in practice they convert at significantly higher rates. A visual hierarchy that places Shop Pay first, followed by Apple Pay or Google Pay (depending on your audience), followed by the standard checkout button, is a sensible default. Use your theme's section editor or a small CSS adjustment to achieve this if your current layout doesn't reflect it.
For product pages specifically, test the button placement relative to your variant selectors and quantity pickers. Customers need to have made all required product selections before hitting an express checkout button, and if the button appears before the variant selector in the page flow, you risk friction or errors at checkout. Shopify typically handles this logic automatically, greying out the button until variants are selected, but always test on mobile to confirm the experience is seamless end to end.
Testing, Measuring, and Iterating Express Checkout Performance
Once your express checkout is live and configured, treat it as a live experiment rather than a completed task. Set up a simple baseline measurement: record your overall checkout conversion rate (the percentage of sessions that reach checkout and complete a purchase) for the two weeks before and after enabling express checkout buttons on product pages. Even without formal A/B testing, this before-and-after comparison gives you a practical signal about impact.
Shopify's analytics dashboard shows conversion funnel data broken down by step, so you can see exactly where customers drop off. If you're seeing high reach-checkout rates but low completion rates, the issue might be in your checkout flow itself — potentially a mismatch between express checkout expectations and what customers encounter once they tap the button. Things like unexpected shipping costs, missing delivery date estimates, or confusing confirmation screens can all create last-step abandonment.
For merchants who want to go deeper on delivery and checkout optimisation together, tools like DeliveryIQ can help by surfacing delivery expectations at the checkout stage, which reduces the uncertainty that causes last-minute drop-off. Combining fast express checkout with clear, confident delivery messaging addresses the two biggest reasons customers abandon — effort and uncertainty — at the same time.
Common Mistakes Merchants Make With Express Checkout
One of the most common mistakes is enabling express checkout but not testing it end to end from a customer's perspective. It takes five minutes to open your store on a mobile device, add a product to your cart, and attempt to complete a purchase using Shop Pay or Apple Pay. Doing this regularly — especially after theme updates or Shopify platform changes — catches rendering issues, button failures, or flow problems before they cost you real sales.
A second frequent mistake is assuming express checkout is only relevant for consumer brands. B2B merchants, wholesale suppliers, and tradespeople all have customers who value speed and convenience. A restaurant operator ordering supplies, an events manager purchasing branded merchandise, or a facilities buyer restocking equipment all benefit from a one-tap checkout just as much as a consumer buying trainers. The professional buyer is often more time-pressed than the leisure shopper, making friction removal even more commercially important in B2B contexts.
Finally, some merchants enable express checkout but don't communicate it to customers. A short note in your email flows, social captions, or product page copy — "checkout in one tap with Shop Pay" — can prime customers to look for and use the feature. Customer awareness of available checkout options is lower than merchants assume, and a small prompt can meaningfully shift which checkout path customers choose.
Conclusion
Express checkout is one of the highest-return configuration changes available to Shopify merchants, combining ease of implementation with measurable conversion impact. The key steps are straightforward: activate Shop Pay, PayPal Express, Apple Pay, and Google Pay through your Payments settings; position the buttons correctly on product and cart pages; test the experience on mobile; and monitor your checkout funnel data over the following weeks.
The merchants who get the most from express checkout treat it as a system rather than a feature — combining fast payment options with clear shipping communication, sensible button hierarchy, and ongoing testing. Small refinements compound into meaningful revenue gains over time, and the baseline investment is minimal.
