The problem

Reconciliation is tedious matching across bank lines, invoices, and payouts.

How the agent works

The agent proposes matches between bank lines and ledger entries (including split payouts from Stripe or PayPal), explains each match, and lists unmatched items.

Setup steps
  1. Export bank and ledger data
  2. Define matching rules (amount, date window, reference)
  3. Have the agent propose matches with reasoning
  4. Accountant accepts or rejects
  5. Investigate the unmatched list

  • Custom Python agent

Human in the loop

Accountant posts all entries.

Risks and guardrails

Never let an agent post journal entries unsupervised.

ROI notes

Reduces reconciliation time; most value comes from the unmatched list.
