mobile checkout and where most revenue gets lost.
Checkout is rarely one large problem. On mobile, small surprises, keyboards and unclear errors stack up until the customer leaves.
Do not start with a new colour for the checkout button. Test a real order on an average phone, on a slow connection and without a saved address. That is where problems missed by a desktop report appear.
the loss often starts before checkout
Unexpected shipping costs, unclear delivery timing and a discount field send customers looking for information. Show that information in cart and on the product page so checkout only needs to handle details and payment.
| friction | what the customer experiences | what to check |
|---|---|---|
| keyboard | wrong input type | email, phone and postcode fields |
| error | unclear what needs fixing | message beside the right field |
| payment | preferred method is missing | usage by market and device |
| summary | costs appear too late | shipping, tax and total upfront |

measure by step and device
One overall conversion rate does not show where the loss happens. Compare product to cart, cart to checkout and checkout to purchase, split by device, market and payment method.
frequently asked questions
can I fully customise shopify checkout?
The options depend on your plan and checkout extensions. Keep the route simple and only change what solves a measured problem.
is express payment always better?
Not for every customer, but a familiar method can remove a lot of input. Measure usage and success by market.
what should I test after every change?
At least a successful and failed payment, mobile errors, discounts, shipping and the return from external payment apps.
