A mobile checkout can look polished in a desktop preview yet fail when a keyboard covers the button, a field rejects a valid address, or an express wallet is unavailable. Use a real device and a reversible test order to identify the actual obstacle.
Check the real path
- Choose a variant and confirm the same item, price, and quantity appear in the cart.
- Enter a valid address with autofill and without it. Watch for keyboard type, lost values, unclear errors, and controls hidden behind sticky elements.
- Compare the delivery charge and timing shown before checkout with the final total. Note whether the platform adds a fee only after address entry.
- Test every payment option you advertise, including the fallback card path. Record platform, device, browser, and the step of failure.
Decide what to change
A wallet button or sticky checkout control is useful only if the platform supports it and the path remains understandable. Ask a developer to fix a reproducible issue, then retest the complete order. Baymard's checkout research separates ordinary browsing from friction that a store can address.
Put it in the project brief
Before paying for a fix, ask the provider to name the affected page or workflow, the change they will make, how they will test it, and which dependencies or exclusions could change the estimate. Keep the baseline and the completed test so both sides can see what improved.
