The challenge
A financial services business needed to accept and reconcile payments across several different payment gateways and bank channels, but each integration had been built separately over time by different teams, with its own data format, its own retry logic, and its own way of reporting failures. Finance staff had to log into multiple dashboards and manually cross-reference transactions to confirm a payment had actually settled, which was slow and left room for reconciliation errors.
The business also needed every transaction to be auditable — a clear, unchangeable record of what was charged, when, through which channel, and what its final status was — to satisfy both internal controls and external compliance requirements.
Our approach
We designed a unified payments integration layer that sits between the business's internal systems and its payment gateways, normalizing every transaction — regardless of which gateway processed it — into one consistent data model. Retry logic, webhook handling, and failure classification are handled centrally instead of being reimplemented per gateway, and every transaction event is written to an append-only audit log so the full lifecycle of a payment is traceable after the fact.
Reconciliation moved from a manual, multi-dashboard process to a single internal view where finance staff can see a transaction's status across every channel it touched, with automated matching against bank settlement files. Role-based access and detailed logging were built in from the start, since a payments system carries a higher bar for security and auditability than most internal tools.
Outcome
Finance staff now reconcile transactions from one internal view instead of cross-referencing multiple gateway dashboards, and every transaction has a complete, auditable record of its lifecycle. Adding a new payment channel became a configuration step within the existing integration layer rather than a separate development project.
