Express checkout — Apple Pay, Google Pay, PayPal Express, Shop Pay — lets shoppers skip the form-filling checkout entirely. One tap, biometric confirmation, done.
For mobile shoppers especially, this is transformational. The standard checkout form (name, address, email, card number, expiry, CVV) takes 2-3 minutes to complete on a phone. Express checkout takes 5 seconds.
The conversion impact is significant and well-documented. But implementation details matter — the wrong setup can actually hurt conversions. Let us get it right.
The Conversion Case for Express Checkout
Across multiple studies and platforms:
- Apple Pay increases mobile conversion by 10-18% where available
- Google Pay increases Android mobile conversion by 8-15%
- PayPal Express increases overall conversion by 5-12%
- Shop Pay (Shopify ecosystem) claims 1.72x higher conversion than regular checkout
Why the lift? Express checkout eliminates the three biggest mobile checkout friction points:
- Form filling. Typing a shipping address on a phone keyboard is miserable. Express checkout uses stored addresses.
- Card entry. Entering a 16-digit card number on mobile, plus expiry and CVV, without errors. Express checkout uses stored payment methods.
- Account creation. Express checkout authenticates via the payment provider — no store account needed.
When Express Checkout Helps Most
Mobile traffic is high. If 60%+ of your traffic is mobile (typical for most stores), express checkout targets your largest audience.
First-time buyers dominate. Returning customers may have saved addresses and cards. First-time buyers do not — express checkout eliminates their setup friction.
Cart values are low-to-medium. For $15-100 purchases, the checkout form is disproportionate. Express checkout makes impulse and convenience purchases viable.
When Express Checkout Helps Less
High-value purchases. For $500+ orders, shoppers want deliberation that a traditional checkout provides.
Complex products. Custom orders requiring additional information need form fields that express checkout cannot provide.
B2B transactions. Bulk orders with purchase orders and net terms require traditional flows.
Apple Pay on WooCommerce
Apple Pay works on Safari (Mac and iOS), with about 65% of iPhone users having it enabled.
Setup via WooCommerce Payments
- Install and activate WooCommerce Payments
- Go to WooCommerce > Settings > Payments > WooCommerce Payments
- Under "Express Checkouts," enable Apple Pay
- Apple Pay button appears on product pages, cart page, and checkout page
Requirements: HTTPS (SSL certificate), domain registered with Apple (handled automatically by WooCommerce Payments), shopper on Safari with Apple Pay configured.
Setup via Stripe Plugin
- Install Stripe for WooCommerce
- Enable "Payment Request Buttons" in settings
- Stripe automatically shows Apple Pay on supported devices and Google Pay on others
With Stripe, Apple Pay and Google Pay use the same Payment Request API. The button shown adapts to the device.
Google Pay on WooCommerce
Google Pay works on Chrome (desktop and Android), with broad compatibility.
If you have enabled Apple Pay via Stripe, Google Pay is already enabled. No additional configuration needed.
Google Pay specifics:
- Works on Chrome browser (desktop and mobile)
- Uses payment methods stored in Google account
- Supports shipping address selection from Google contacts
- No domain verification required
- Button style is customizable (black, white, or outlined)
PayPal Express Checkout
PayPal has the widest user base — over 400 million active accounts worldwide.
Setup
- Install PayPal Payments for WooCommerce
- Connect your PayPal business account
- Enable "PayPal Express Checkout"
- Configure button placement (product page, cart, checkout, or all three)
PayPal Express vs. Standard PayPal
Standard PayPal redirects the shopper to PayPal's site. PayPal Express uses an in-page popup — the shopper logs in within the popup, confirms payment, and returns without leaving your store. Much smoother.
PayPal reports Express Checkout converts 2-3x better than standard PayPal.
Buy Now, Pay Later (BNPL)
BNPL is not technically express checkout, but it serves a similar function: reducing payment friction.
Options for WooCommerce
- Klarna: Split payments into 4, or pay in 30 days. Popular in Europe.
- Afterpay/Clearpay: 4 installments. Strong in Australia, UK, US.
- Affirm: Longer-term financing (3-36 months). Better for higher AOV.
- PayPal Pay in 4: Integrated with PayPal, no additional plugin needed.
BNPL Conversion Impact
- Average conversion lift: 20-30% for orders over $50
- Average AOV increase: 30-50%
- Highest impact for stores with $50-500 average order values
Button Placement Strategy
Where you place express checkout buttons matters as much as which methods you offer.
Product Page
Enables impulse purchasing. Shopper sees a product, taps "Buy with Apple Pay," and the purchase is complete without visiting the cart or checkout.
Best for: Single-item purchases, impulse buys. Caution: May reduce items per order if shoppers buy one item instead of building a multi-item cart.
Cart Page
Serves shoppers who have built their cart and want to skip the checkout form.
Best for: Multi-item orders, considered purchases, stores with high cart-to-checkout drop-off. Placement: Above and below the cart items. For more cart page optimization strategies, including cross-sells and trust signals.
Checkout Page
Catches shoppers who see the form and think "I do not want to fill this out."
Best for: Stores with complex checkout forms. Placement: Above the checkout form, clearly separated with an "Or" divider.
Mini Cart / Cart Drawer
If your theme uses a slide-out mini cart, adding express payment there enables the shortest path: Add to Cart > Express Pay > Done.
WooCommerce Payments vs. Stripe: Which to Use
WooCommerce Payments
Pros: Built by Automattic, dashboard integrated into WooCommerce admin, automatic Apple Pay domain verification, multi-currency support.
Cons: Powered by Stripe under the hood but adds abstraction, feature updates may lag, disputes managed through WooCommerce dashboard.
Stripe for WooCommerce
Pros: Direct Stripe integration with latest features, full Stripe dashboard, broader payment method support (Link, iDEAL, SEPA), Stripe Radar for fraud.
Cons: Two dashboards, manual Apple Pay domain verification may be needed.
Recommendation
For most stores: start with WooCommerce Payments for simplicity. If you need advanced Stripe features (Radar rules, specific payment methods), switch to the direct Stripe plugin.
Testing Express Checkout Performance
After implementation, measure:
Primary metrics:
- Conversion rate change (overall and mobile-specific)
- Express checkout adoption rate
- Average order value for express vs. standard checkout
- Cart-to-order completion rate
Segmentation:
- New vs. returning customers (express helps new customers more)
- Mobile vs. desktop (express helps mobile more)
- Low vs. high AOV orders
A/B testing: Show express buttons to 50% of traffic, hide from 50%. Run 2-4 weeks. Measure overall revenue impact, not just conversion rate.
Common Implementation Mistakes
Too many buttons. Showing Apple Pay, Google Pay, PayPal, Klarna, Afterpay, and Shop Pay simultaneously creates choice paralysis. Show the 2-3 most relevant.
Wrong button order. Show the most popular option first. If 70% of mobile traffic is iOS, Apple Pay goes first.
No fallback. If express checkout fails, the shopper should seamlessly fall back to standard checkout.
Ignoring the standard checkout. Express checkout does not replace traditional checkout. Some shoppers prefer forms. Optimize both paths.
Not testing on real devices. Apple Pay only appears on Apple devices. Google Pay only in Chrome. Test on actual phones.
Express checkout is one of the highest-ROI checkout optimizations you can make. The setup is straightforward, the conversion lift is well-documented, and the shopper experience improvement is immediate. If you have not added it yet, do it this week.
