Start with the decision
Before checkout, a customer needs to understand the product, price and relevant delivery information. Make those details easy to find and use accurate product descriptions. A well-presented catalogue supports the buying decision before a payment form appears.
Design out the friction
Review the cart and checkout as one journey. Let customers check quantities and costs, explain required fields and make errors understandable. Choose payment integrations that suit the store's requirements and test the complete flow before launch.
Learn after launch
Review unsuccessful checkouts and customer questions when reliable information is available. Check the experience after changes to products, shipping settings or payment tools. Improve the steps you can observe without assuming that every abandoned cart has the same cause.
