A drop between cart and purchase does not identify its own cause. Some visitors are comparing prices; others encounter a broken payment step or an unexpected delivery charge. Audit the checkout path before changing the entire store.
Use an approved test payment method or the platform’s testing environment. Coordinate live tests with the store owner so inventory, accounting, and fulfillment are not accidentally triggered.
Start with a realistic basket
Choose a product with options, select a variant, and add it to the cart on a phone. Confirm that the cart preserves the selected size, color, quantity, and price. Then change the quantity and remove an item.
If the store has shipping thresholds, test a basket below and above the threshold. For products with restricted destinations, test an ineligible address and read the explanation the customer receives.
Look for late surprises
Record the first point where shipping charges, required fees, and delivery timing become clear. If those details appear only at the last step, consider explaining them earlier. The shipping information guide shows where useful context belongs.
Check whether discounts behave as described. An expired promotion should produce a clear message rather than an unexplained total. Do not let an oversized coupon field make customers think they must leave the store to find a code.
Test errors, not just the ideal path
Enter an incomplete address or omit a required field. Does the message identify the exact problem? Are the customer’s other entries preserved? Can the affected field be reached without losing the basket?
Check a declined test payment using the platform’s documented test method. The page should explain the next step without suggesting that an order succeeded when it did not. Avoid collecting sensitive payment details in screenshots or your test notes.
Review account and contact requirements
If an account is mandatory, determine whether the business actually needs that requirement. Where guest checkout is available, make it easy to find. Explain why a phone number is needed rather than requiring it without context.
Make support reachable, but avoid adding widgets that obscure fields or payment controls on small screens. A link to assistance should preserve the customer’s progress where possible.
Verify the outcome at both ends
Confirm that the customer sees the right order summary and that the store receives one correctly recorded order. Check confirmation messages, selected variants, shipping method, and any stock changes in the test environment.
Write findings as observable problems: “Postal-code error clears the street address” is more useful than “Checkout feels bad.” Fix the most disruptive issues first, then compare results over enough orders to avoid drawing conclusions from a handful of visits.
