Optimise your PrestaShop checkout: identify and remove purchase barriers

A customer has found the right product and added it to the basket. They now need to complete the order reliably. If a form rejects an address, a shipping option disappears or the return from the payment provider fails, a better product page will not solve that problem. Checkout optimisation starts with a reproducible ordering test.

At sjmedia, we consider PrestaShop a strong foundation for adapting checkout to merchants and customers. We recommend checking existing settings and specific faults first. An additional checkout module is not automatically the answer. Shipping rules, the theme or interactions between existing extensions may be responsible.

Where should a checkout assessment begin?

Focus the initial assessment on the journey from basket to confirmed order. Our online store user experience guide covers search, navigation and product pages. Here, the question is whether a customer ready to buy can complete the final steps without unnecessary barriers.

Start with cases that matter to your store: a new customer on a smartphone, a returning buyer and, where relevant, a business customer. Use realistic baskets, delivery countries and payment methods. Work in a suitable test environment; a successful sandbox payment should be supplemented before launch by a controlled check of the intended live journey.

Which six areas should merchants test first?

For each test, record the device and browser, the expected outcome and what actually happened. Screenshots and identifiable test order numbers make subsequent investigation easier.

• Entry: can customers find guest checkout where offered, and does the basket survive sign-in?
• Address: do typing, autofill and corrections work on a smartphone with your relevant address formats?
• Shipping: are appropriate delivery methods and clear charges shown for the selected address?
• Payment: can customers select the method they need and recover sensibly from cancellation or rejection?
• Completion: do the order, payment status, confirmation and downstream handover agree?
• Going back: are useful entries retained when customers revisit a step or correct an error?

These six areas are a working framework, not proof that a store is faultless. Add rules specific to your business, such as a minimum order value or a separate delivery address.

How does PrestaShop support guest ordering and order rules?

PrestaShop documents guest checkout and minimum order value among its order preferences. Check those foundations first. Changing a button colour will not resolve an unintended minimum purchase amount.

For many consumer stores, an easy-to-find guest route is worth assessing. In B2B, an approved company account or negotiated terms may intentionally shape the journey. Access requirements should be clear to the customer and appropriate to the business model.

We favour PrestaShop for tailored ordering workflows because it can be developed around specific needs. Whether a change belongs in configuration, the theme or a module depends on the version and installation. Test with the actual payment and shipping modules in use. More extensions also mean more interactions to check after updates.

What makes mobile forms unnecessarily difficult?

Test on a real smartphone rather than only narrowing a desktop browser window. Does the keyboard obscure a field? Does autofill supply the correct address? After an error, can the customer identify the field requiring correction? Check whether valid information remains in place.

The W3C guidance on form feedback emphasises understandable error descriptions, identifying the affected field and explaining how to correct the problem. A red border alone does not explain an error. This also supports more accessible forms, but does not replace a complete accessibility assessment.

How should you test shipping and payment redirects?

A checkout can function technically while applying the wrong shipping rule. Test representative baskets around important thresholds, such as just below and above free shipping eligibility. German and Swiss addresses may follow different rules; test the countries you actually serve.

For payments, check more than the success page. Confirm the order receives the appropriate store status and is passed correctly to the ERP or shipping process. Also test a cancelled payment. Customers should understand whether an order already exists and how to continue without accidentally ordering twice. Our payment methods guide separately covers method selection.

Which measurements show whether a change helps?

Define the comparison first. For example, examine completed ordering journeys that can be unambiguously attributed to observed checkout starts. Apply consistent counting rules and a suitable reporting window. Repeated events, different devices and delayed purchases can affect attribution.

Google documents GA4 events including begin_checkout and purchase. Your implementation must trigger them correctly and be tested. Analytics totals and store orders are not automatically identical because collection differs; investigate consent, blockers and duplicate recording, among other factors.

Compare reasonably similar periods and segment by device, payment method and traffic source. More purchases after a change do not establish causation if a discount campaign or different advertising ran at the same time. With limited data, observed test failures and customer feedback may provide a stronger initial basis than an apparently precise improvement percentage.

What should you improve first?

A reproducible fault blocking an important ordering scenario takes priority over cosmetic changes. Next address frequent, evidenced usability barriers. Treat changes without a clearly identified problem as hypotheses. Define an expected outcome and a rollback option for each intervention.

We recommend improving an existing PrestaShop checkout step by step and retesting the complete ordering journey after each change. As a PrestaShop agency, we combine technical changes with conversion optimisation. The goal is a reliable purchase journey whose improvement can be assessed in context, not a promised standard uplift for every store.
