Ledgerloop

Organisations taking card payments frequently reconcile payouts manually: processor dashboard against accounting ledger, line by line, with variances caused by fees, refunds, and disputes. The work is slow, quietly error-prone, and a mismatch discovered weeks later is expensive to unwind.

• A webhook receiver ingesting payout, charge, refund, and dispute events with signature verification and replay-safe, idempotent writes.
• A reconciliation engine that groups transactions into payout batches and attributes each variance line to fee, refund, dispute, or unmatched.
• A ledger review view surfacing only exception rows for human attention, with a controlled export back into the accounting system.

Across a 12,000-transaction dataset spanning 90 payout batches, the engine attributed every variance except deliberately corrupted control rows, reducing human review from every line to exceptions only. A month of data reconciles in under a minute against a full manual pass.
