BigCommerce Checkout Optimization Guide

Checkout is where the most ready-to-buy shoppers slip away, and BigCommerce gives you a real head start: its optimized one-page checkout is fast and conversion-friendly out of the box. That means your job is less about rebuilding checkout and more about making sure nothing around it undermines the advantage you already have. This guide covers the levers that matter.

This is one execution piece of our BigCommerce conversion rate optimization guide, and it pairs closely with reducing BigCommerce cart abandonment.

Start from a strong default

BigCommerce's one-page checkout already does something powerful: it puts the whole process on a single screen, so shoppers are not clicking through multiple steps and losing momentum. Fewer steps mean fewer places to abandon. You have meaningful control over how it looks and behaves, and on higher plans you can customize it further through BigCommerce's checkout tools. But the foundation is fast, so protect it rather than fight it.

1. Turn on express and digital wallet payments

Express checkout options are the biggest single lift BigCommerce hands you. Digital wallets like Apple Pay and Google Pay, along with PayPal and other one-click options, let returning shoppers pay in a couple of taps instead of typing an address. This matters most on mobile, where typing is exactly where checkouts die. Enable the full set of wallets your customers use. Fewer keystrokes between deciding to buy and paying means more completed orders.

2. Allow guest checkout

Forcing account creation is one of the top reasons shoppers abandon, and it is entirely self-inflicted. Make sure guest checkout is enabled so anyone can buy with just an email. You can still invite them to create an account after the purchase, when the friction is gone and the sale is already yours.

3. Remove the shipping surprise before checkout

The single most-cited reason people abandon is extra cost revealed too late. BigCommerce's real-time shipping quotes help, but the fix starts earlier:

• Show shipping cost or a free-shipping threshold in the cart, so the total is never a shock at the final step.
• Use a free-shipping promotion where your margins allow, one of the most reliable conversion levers there is.

By the time a shopper reaches the one-page checkout, nothing about the total should surprise them.

4. Keep the checkout clean and minimal

Even on a one-page checkout, every unnecessary field is friction. Ask only for what you need to fulfill the order, make sure mobile inputs trigger the right keyboard, and lean on address autocomplete. Keep any promotional distractions off the checkout itself, since the shopper is there to finish, not to browse.

5. Reinforce trust at the payment moment

BigCommerce checkout is secure, but the shopper does not always feel that. Keep the checkout visually consistent with your brand, show a secure-payment signal, make your return policy easy to find before the final step, and offer a visible way to reach a real person. For a newer brand, these small reassurances are the difference between a completed order and a hesitation.

6. Do not lose the advantage on mobile

Most of your traffic is on a phone, and mobile converts at roughly half the desktop rate. The one-page checkout helps, but confirm the whole flow works with a thumb: buttons reachable, wallets prominent, fields easy. The mobile checkout is where the biggest gains hide.

What to measure

Baseline these before you change anything, and split by device, since mobile abandonment runs far higher:

• Checkout-started rate (cart to checkout), which your shipping and cart work moves.
• Checkout completion rate (checkout to purchase), which your express-payment, guest-checkout, and trust work moves.

Give each change time to gather real data, and compare against a clean baseline rather than a single day. When you have the traffic, prove the bigger changes with a controlled test, using the method in our master guide to ecommerce conversion rate optimization.

Protect a good default, then sharpen it

BigCommerce gives you a fast one-page checkout, so most of the work is making sure nothing undermines it: enable the wallets, allow guests, kill the shipping surprise, and keep the flow clean on mobile. Do those and more of your ready-to-buy shoppers finish. If you want a read on exactly where your checkout is leaking, that is what our free conversion audit is for. No call, no card.
