Checkout, back office and processor, end to end
PayWasp needed a full payment processing set-up: a checkout that merchants embed on their own websites, a back-office dashboard for transactions, reconciliation and reporting, and a secure integration with payment processor SDKs. PCI compliance had to be considered throughout, and checkout had to be smooth for the end consumer.
Proof of concept first
We validated the system as a PHP proof of concept before moving it to the production React/Java architecture. The production platform has three applications:
- Altruon Checkout — the embeddable merchant checkout widget
- Altruon Backoffice — the admin dashboard for transaction management and reporting
- Payment SDK connector — a Java connector for secure processor integration
The dashboards are React 19 with a Bootstrap 5 UI, and the architecture follows PCI-compliant patterns.
In production
PayWasp serves merchants with the embeddable checkout and oversees their transactions in the back office. Checkout, admin and processing are separate components, so each scales on its own.
