Find where customers hesitate
Start by walking through checkout on a phone and a laptop. Note where the page asks for information, introduces a new cost, or makes the next step unclear.
If analytics are available, compare the number of people who start checkout with those who reach confirmation. Treat that as a signal for investigation, not a diagnosis by itself.
Keep the purchase details visible
Show the product, quantity, delivery cost, taxes where known, and total before the final action. Customers should not have to return to the cart to check what they are buying.
Explain delivery timing and return terms close to the decision. Avoid introducing a new fee or required account late in the flow.
Make forms feel manageable
Ask only for information needed to take payment and deliver the order. Use suitable input types, sensible autocomplete values, and clear inline validation.
Offer guest checkout when an account is not essential. After payment, show a confirmation page and send a receipt so the customer knows the order was received.
