PrestaShop checkout failure on an online store

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.

  • Retour boutique cassé

    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  • Outdated module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

    Une règle de transport, un poids ou un pays mal configuré bloque l'étape avant le paiement.

  • Inconsistent order statuses

    Paid orders not confirmed, stock levels not updated, and emails never sent.
