The checkout test: Before paying, can a customer understand the full order, what happens next, and where to get help?
A customer who reaches checkout has already made a decision to buy. Confusing fees, unexpected account requirements, or unclear error messages can make the final steps harder than they need to be.
Show the full cost and delivery details before the customer confirms payment.
ILLUSTRATIVE EXAMPLECheckout improvements are different from general site-speed work: the focus here is on clarity, confidence, payment handling, and reducing avoidable steps after a shopper chooses a product.
1. Show the real total as early as you can
Customers should be able to understand the product price, shipping choices, taxes when available, and any other required charges before they commit to an order. If a cost depends on delivery details, explain when it will be calculated and show it before the final confirmation. Hidden costs are frustrating and make it difficult for shoppers to compare options.
Keep return, delivery, and contact information easy to find. Plain language about when an order ships, how returns work, and what happens after payment helps people make an informed decision.
2. Do not make account creation a surprise requirement
Let customers know whether they can check out as a guest. An account can be useful for repeat purchases, but forcing registration before purchase adds work for people who only need to place one order. If you offer account creation, make it an understandable option and avoid asking for profile details unrelated to the transaction.
3. Use a payment setup you can support
Choose a reputable payment provider and understand which parts of the checkout your business operates. Hosted or provider-managed payment components can reduce the amount of card data your own site handles, but they do not automatically remove every security responsibility. Confirm the provider's integration guidance, protect administrator accounts, keep software updated, and ask your acquiring bank or qualified payment advisor what applies to your setup.
Never collect card details in ordinary email, chat, or an unprotected custom form. The PCI DSS provides a baseline of technical and operational requirements for organizations that store, process, or transmit payment card data or could affect its security.
4. Make the checkout easy to complete
- Ask only for details necessary to fulfill and support the order.
- Label every field and explain errors next to the field that needs attention.
- Make the page usable with a keyboard and on a small touchscreen.
- Keep entered information when a validation error can be corrected.
- Show a clear order summary before the customer submits payment.
Do not use a color change as the only signal that payment failed or a field needs attention. Plain text and visible focus help customers understand what to do next.
5. Test the complete purchase path
Place test orders on a phone and a desktop using the payment provider's recommended test mode. Check successful payment, declined payment, invalid address, shipping choices, confirmation email, inventory updates, and refunds or cancellations. Verify that staff know where to find order status and whom to contact when a payment is pending rather than clearly successful or failed.
After changes go live, monitor abandoned checkout steps alongside customer questions and completed orders. A sudden change may reflect a new setting, stock availability, shipping rules, or a tracking issue—not necessarily a design problem. Make one change at a time when possible, and keep a way to restore the previous checkout if a release causes trouble.
Before opening your online store
- Review the displayed total, shipping, delivery, return, and contact information.
- Confirm that guest checkout and account options are clear.
- Check payment-provider settings, administrator access, and support contacts.
- Test a successful order and common failure paths on mobile and desktop.
- Verify receipts, order status, cancellations, and refunds with staff.
