- Recovery of orders stuck awaiting payment
- Quote approved before any work begins
The symptoms we check first
A systematic diagnosis, in the right order: we isolate the cause before changing a single file.
Payment wrongly declined
The module returns an error even though the bank authorises the transaction.
Broken store return emails
The customer pays but is never redirected to the confirmation page, leaving an orphaned order.
Outdated module
A module version that is incompatible with your PrestaShop version, PHP version or the provider’s new API.
Invalid API keys
Test keys left in production, an expired certificate, or a suspended payment provider account.
Shipping carrier or cart rule
A misconfigured shipping rule, weight or country blocks the step before payment.
Inconsistent order statuses
Paid orders not confirmed, stock levels not updated, and emails never sent.

Frequently Asked Questions
My customers paid but received no confirmation. What should I do?
We reconcile payment provider transactions with PrestaShop orders, then correct order statuses and resend confirmation emails.
Which payment providers do you work with?
Stripe, PayPal, PayPlug, Systempay, Monetico, Mollie, Alma and most French payment modules, as well as custom-built modules.
How long does it take to restore payment processing?
Most payment issues are fixed the same day, often within one to two hours of work.
