A fintech product moves money and has to explain every movement. Operations reconcile the ledger against the payment provider each morning, chase the items that do not match, and answer a customer who sees a balance they did not expect. Compliance asks for the evidence later.
The system we build keeps that record. Every transaction has a state and a source, reconciliation runs on a schedule with exceptions listed, and access to account data is logged so a review is an export rather than a search through email.
