About AppPay

AppPay is a secure payment integration that connects your payment gateway directly to your ERP solution. When a customer pays, AppPay fetches the sales order straight from your ERP, builds a verified gateway checkout, and once the payment gateway confirms the payment through its instant transaction notification, writes the transaction back into your ERP automatically. Orders are confirmed, invoices are settled, and accounting records stay accurate without anyone re-keying a thing. The bridge uses read-only order retrieval, signature-verified notifications, and a full audit trail of every payment attempt.

It is built for South African merchants who sell through ERP and eCommerce platforms and accept online gateway payments, especially stores whose built-in portal checkout is unreliable or unavailable. Customers simply open a payment link, complete the familiar secure checkout, and return to their order, while back-office teams see every transaction and its sync status on the dashboard.

AppPay is developed by Applicable, a software company that builds practical, reliable integrations keeping business systems talking to each other. Every payment flows through a hardened middleware layer so sensitive credentials and financial data never sit in the storefront itself.
