Despite being ready to buy, a client may abandon the shopping process due to the checkout demanding too many things from them, concealing costs, and making an easy process difficult. As per Baymard, the current average rate of cart abandonment is 70%. On the other hand, 18% of those surveyed said that they abandoned their shopping carts because the checkout process was too long and complicated.
In a PrestaShop store, checkout optimisation involves reducing barriers and not increasing its functional capacities. It would mean consolidating the customer data, shipping, payment, and order details in one flow and enabling the merchant to choose what he wants his clients to do on the checkout page. The PrestaShop One Step Checkout Addon from Knowband is one tool built around that goal.
The objective should be to make each part easy to navigate through, fill out, and recover from any potential errors.
Why Checkout Optimisation is Important for a PrestaShop Store
The checkout is the place where browsing leads to purchase transactions. Once a client has picked a product, most of the purchasing process is already done.
According to Baymard’s findings of 2025, 39% of consumers abandon due to excessive additional fees, 19% of consumers abandon due to the site’s request for the creation of an account, and 18% abandon because of the complexity or length of the checkout.
These percentages do not imply that every case of cart abandonment could be addressed with modifications of the checkout. Some visitors are simply browsing or comparing products. The useful distinction is between unavoidable abandonment and abandonment caused by problems that the store can actually fix.
For a PrestaShop merchant, that means looking closely at:
- How many fields customers must complete
- Whether shoppers can buy without creating an account
- How shipping and payment choices are presented
- Whether errors are explained while the customer is entering information
- Whether the order summary remains clear
- How the checkout behaves on smaller screens
- Whether customers understand what they need to do next
A shorter checkout can help, but only when shortening it doesn’t remove information customers need to make a confident purchase.
Start by Removing Checkout Friction, Not Useful Information
A common mistake is treating every checkout field as equally necessary. In practice, some information may be essential for fulfilment or payment, while other fields may have been added years ago and never reconsidered.
Baymard’s research shows that checkout flows can often be simplified substantially. The research carried out by the company reveals that its average checkout contained significantly more form elements compared to the checkout designed with usability in mind. Furthermore, the testing performed by the company revealed that complex checkout is one of the recurring usability issues.
In the context of a PrestaShop store, each of the fields should be assessed using the following simple test: does the business need this particular piece of information in order to process and fulfill the order, meet some requirement, or provide a useful service?
PrestaShop One Page SuperCheckout makes it possible to show or hide various address fields, set them as required and change their order. The manual also documents inline validation, saved addresses, country detection, and Google address autofill.
That gives merchants more control over the checkout rather than forcing every customer through an identical collection of fields. This is the core value of a well-configured PrestaShop One Step Checkout Addon — control over what appears, not just how it looks.
Keep validation close to the problem
A checkout error becomes more frustrating when the customer discovers it only after submitting a large form.
Inline validation can make the interaction clearer by checking fields such as names and ZIP codes as customers complete them. The module’s manual specifically documents this option for the address section.
Address validation also deserves attention because incorrect addresses can create problems after the order has already been placed. If your store uses Google address autofill, remember that the documented setup requires a Google API key.
The principle is simple: prevent avoidable mistakes before the customer reaches the final order submission.
When One Page Checkout PrestaShop Makes Sense
The fact that the checkout takes place on one page is not automatically better than any multi-step checkout. Checkout type should match the complexity of the purchase and the amount of information customers genuinely need to provide.
For relatively straightforward purchases, putting the relevant sections together can reduce unnecessary navigation. Customers can see their details, delivery choices, payment options, and purchase information within the same overall checkout interface.
The module’s front-end configuration is designed around this approach, allowing merchants to place checkout elements on one page and control which fields appear. For stores where One Page Checkout PrestaShop setup replaces a fragmented multi-step flow, this can reduce unnecessary navigation without adding complexity.
That can be particularly useful when a store’s existing flow requires customers to move repeatedly between pages for information that could reasonably be handled in one place.
That said, do not make the checkout page overly control-rich. The visual hierarchy should be clear. Group related information, keep important actions visible, and avoid displaying optional fields simply because the module allows them.
Baymard’s research also states that checkout processes must be predictable.
Provide Users With an Option to Decide on Logging In vs. Guest Checkout
Account creation can be a significant point of resistance. Baymard’s 2025 checkout abandonment research revealed that 19% of the respondents left the process as the site asked them to register.
That makes guest checkout more than a convenience feature. For first-time customers, it can remove a decision that has nothing to do with the purchase itself.
The module provides guest checkout, registration, and login options. Administrators can also choose the default checkout option shown to customers.
Social login is another option documented by the module, with Google, Facebook, and PayPal login configurations available when the required credentials and external service setup are completed.
A sensible configuration depends on your audience. If a large share of customers are first-time buyers, making guest checkout prominent can reduce unnecessary resistance. If registered customers frequently return, a convenient login path can save them from repeatedly entering information.
Make Shipping and Payment Choices Easy to Understand
Users should not be required to guess what delivery option and payment type to choose.
A checkout should present relevant shipping options clearly and make the relationship between delivery and payment methods understandable. The module lets administrators enable or disable delivery and payment methods, select default methods, and control how these options are displayed.
The Ship2Pay functionality can also map particular payment methods to selected delivery methods. This helps prevent customers from being shown payment options that aren’t appropriate for their chosen delivery method.
The payment gateway itself is only part of the experience. Customers also need enough information to understand what they’re paying, which delivery method they’ve selected, and what happens after they submit the order.
That makes the order summary an important part of checkout rather than a decorative final box.
The module provides controls for displaying the cart and order total, including options related to product images and summary information.
Optimise the Checkout for Mobile Use
A checkout that works on desktop can still be awkward on a phone. Small screen sizes can highlight issues like oversize forms, complicated dropdowns, too much scrolling, or mismanaged payment or delivery buttons.
According to Baymard’s 2025 benchmark, 63% of mobile sites in the research had either “mediocre” or worse checkout UX score.
But a good responsive design is not enough to solve mobile conversion issues. The fields still need to be logically ordered, the interface must be readable, and customers should not have to repeatedly zoom or scroll sideways.
The supplied module documentation describes the checkout as responsive for mobile and tablet devices. Knowband’s PrestaShop One Step Checkout Addon is built with this in mind, but responsiveness still needs to be tested against real device behavior, not just assumed from the module description.
When testing your own store, don’t stop at checking whether the page technically fits the screen. Place an actual test order from a phone. Test the change of addresses, shipping options change, inputting incorrect values, coupon codes usage, and payment.
Such testing can identify issues that cannot be revealed using responsive design test alone.
Use Autofill and Saved Information Where It Actually Helps
Typing an address on a mobile device is tedious. If customers regularly enter the same information, reducing manual entry can make the process noticeably easier.
The module includes country auto-detection and Google address autofill. The latter uses Google Places integration and requires the relevant API key to be configured in the back office.
Saved addresses are also supported. Customers can save an address and later update or delete it, according to the module documentation.
These options are most useful when they reduce work without taking control away from the shopper. Auto-filled information should remain easy to review and correct.
Keep Checkout Customisation Focused on the Customer
PrestaShop stores often have different requirements. A B2B store may need company details or VAT information, while a consumer store may need very little beyond delivery and payment information.
Module supports custom fields that may be placed in various locations such as shipping address, payment address, cart, or customer registration section. Such fields can be added, edited, deleted, and configured.
Customer profiles extend this approach by allowing different checkout information to be presented for different customer categories. The manual gives examples such as business and personal customers, with separate fields and required-field settings.
Use this flexibility carefully. Each new field provides yet another place to make a mistake, so customizations must help fulfill an actual business need rather than just make the checkout seem more complete.
Coupon codes, for instance, are helpful for merchants that have promotions. For merchants that don’t have promotions, asking the client to hunt for the code may only distract him from finishing the transaction.
Make Pricing and Consent Transparent
Unexpected charges are one of the most common reasons for abandoning checkouts. In 2025, according to Baymard’s research, 39% of shoppers stated that unexpected costs like shipping, taxes, and fees were their reasons for abandoning the checkout.
The customer needs to know how much money he is going to pay before the transaction.
The module allows choosing the way in which the total price of products will be calculated: PrestaShop defaults, taxes included, taxes excluded, or both.
The module also provides a free-shipping banner condition based on a minimum order amount.
Privacy consent needs the same level of clarity. The documented GDPR settings in the Knowband module allow administrators to create multiple consent policies and decide whether individual policies are required or optional. Customer consent records can include the order reference, customer information, accepted consent, date, and time.
The exact consent configuration should still reflect your legal requirements and privacy policy rather than relying on a module setting alone.
Measure Checkout Problems Instead of Guessing
A checkout redesign shouldn’t end when the new page goes live. The useful question is whether customers are actually completing more orders and where they continue to struggle.
The module includes abandoned checkout statistics covering orders, abandoned checkouts, revenue generated, revenue lost, and checkout conversion. Reports can be reviewed over specified day, week, month, or year periods.
The checkout behaviour report goes a step further by showing the percentage of information filled in or skipped by customers who abandoned the checkout.
That information can help identify a field or section that deserves investigation.
For example, suppose many abandoned sessions reach the address section but leave before completing it. Instead of immediately redesigning the entire checkout, examine the fields in that section. A mandatory field may be unnecessary, unclear, incorrectly validated, or difficult to complete on mobile.
That kind of diagnosis is more useful than assuming that a single-page layout will automatically solve every conversion problem.
A Practical PrestaShop Checkout Optimization Checklist
Before considering your checkout finished, test the complete customer journey. A PrestaShop One Step Checkout Addon gives you control over the layout, but the configuration still needs to be validated through real testing.
Check the information customers must enter
Remove fields that don’t serve a clear purpose. Mark genuinely required information clearly and keep the order logical.
Test every customer path
Try registered checkout, guest checkout, and any social login options you have enabled. Check what happens when a customer enters invalid information.
Review delivery and payment combinations
Make sure available shipping options match your business rules and that payment methods behave correctly after customers change their delivery selection.
Test the order summary
Make sure the customer understands all the information about the product, its total price, taxes, discounts, and shipping costs.
Test on a real phone
Don’t rely exclusively on desktop browser resizing. Complete an actual order using a mobile device and test the difficult interactions manually.
Review abandonment data
Compare completed orders with abandoned checkouts over consistent time periods. Look for patterns rather than reacting to one unusual day.
Recheck after every major change
Payment modules, shipping modules, themes, custom JavaScript, and PrestaShop updates can affect checkout behaviour. A checkout that worked before an update should still be tested afterwards.
Where PrestaShop One Step Checkout Addon Fits Into the Optimisation Process
Optimisation of checkout should not be about just converting multiple pages into one page. It should involve optimizing the process while retaining the same amount of data, payment methods, delivery options, validation processes, and consent forms that are necessary. A PrestaShop Simplified Checkout Addon supports that goal when configured around the store’s actual requirements rather than default settings.
The PrestaShop One Page SuperCheckout module provides controls that support that process, including guest checkout, field management, inline validation, address autofill, payment and delivery configuration, custom fields, responsive checkout, consent management, and checkout reporting.
For a merchant dealing with unnecessary fields, fragmented checkout navigation, or limited control over the checkout layout, a PrestaShop Quick Checkout Addon can be worth evaluating as part of a broader optimisation project.
The important part is how the configuration is used. A badly configured one-page checkout can still be crowded, confusing, or difficult to use.
The Best Checkout Is the One Customers Don’t Have to Think About
Checkout optimisation works when the customer can move from product selection to order confirmation without unnecessary decisions or interruptions.
That means fewer irrelevant fields, a visible and understandable order total, a straightforward guest path, sensible delivery and payment choices, useful validation, and a layout that works on the device customers actually use.
A PrestaShop Simplified Checkout Addon can support those improvements, but the configuration should follow your customers’ behaviour rather than a generic checklist. Use your checkout reports, test real purchase journeys, and remove friction where the evidence shows a problem.
For stores that need more control over a single-page checkout experience, a PrestaShop Quick Checkout Addon from Knowband is one option to explore. The module’s documented controls make it possible to adapt checkout fields, customer paths, payment and delivery displays, consent settings, and reporting to the store’s requirements.
A faster checkout is useful. A checkout that makes the purchase feel straightforward is even more valuable.
