From payment to fulfilment

Payment gateway integration.

Checkout is a crucial part of the customer experience. ExecuteOS integrates your approved payment provider account with your website or application. Based on the features available to that account, we connect payment initiation, provider notifications, order states and post-payment actions. The goal is a payment journey that customers can understand and your team can follow.

Shaped around your project
ExecuteOS

01 / The need

The need

A successful payment that leaves an order unchanged creates unnecessary work. Duplicate notifications can trigger repeated actions, while unclear failure messages leave customers unsure whether to try again. Adding a checkout button alone does not address these issues. Payment results need to be verified on the server and associated with the correct order.

02 / The approach

The approach

We first assess the provider against your business location, account eligibility and requirements. We then implement checkout and notification handling using the provider’s documentation. Successful payments, failures and repeated notifications are checked in the available test environment. Refunds, instalments or subscriptions are included only where supported by the provider and your approved account.

What can we build?

  • Payment initiation and verified results with an eligible provider
  • Payment notifications linked to the correct order status
  • Post-payment notifications or digital fulfilment connections
  • Refund, instalment and subscription flows where supported

FREQUENTLY ASKED QUESTIONS

01Do you provide payment processing accounts?

No. Account applications and approval are handled by the bank or payment provider. We develop the technical integration for your approved business account. Provider approval and processing fees are outside the integration service.

02Can we use Stripe, iyzico or PayTR?

That depends on where your business is registered, its account eligibility and the features required. We check those conditions before implementation. Providers do not necessarily offer the same availability or features across countries and accounts.
