The starting point

A business needed each invoice to offer the payment methods selected by its team, with successful transactions written back to its accounting system.

What we built

  • An invoice-linked checkout that validates the request and offers the configured payment methods.
  • Payment-provider integration and server-side capture handling.
  • Webhook handlers that record successful payment events in the accounting system.

What the work delivered

The checkout was implemented and a payment test was reported complete during handover. This account describes that delivered scope; it does not claim current uptime, reconciliation accuracy or commercial gains.

Client identity, invoice details and payment data are withheld. The diagram illustrates the scope and contains no client information.
