01 — Challenge

Six banking partners, one month-end scramble: reconciliation done by hand against a growing volume of transactions.

Treasury had real-time transaction data but no real-time view of it — visibility arrived days later, in a spreadsheet someone built manually.

Discrepancies surfaced at month-end, when they were hardest and most expensive to trace back to their source.

02 — Approach

PHASE 01 Research Mapped the reconciliation workflow across all six banking partners and where it broke down.

PHASE 02 Architecture Designed an event-driven pipeline that could reconcile transactions as they happened, not after.

PHASE 03 Development Built the dashboards, reconciliation engine, and audit trail as one integrated system.

PHASE 04 Rollout Parallel-run against the manual process for one full close cycle before cutover.

03 — Solution

Built for the workflow

Real-time treasury dashboards

Live position across all six partners, replacing a report that used to take days.

Automated reconciliation

Transactions matched against bank data as they arrive, with exceptions flagged immediately.

Payment integration layer

Audit-ready reporting

Every reconciliation decision logged and traceable, ready for regulatory review.
