Reconciliation
A control process that confirms consistency between multiple financial records, such as ledgers, bank statements, or payment rails. Finance and operations teams use it to surface discrepancies and ensure completeness, resulting in reliable data that supports both accuracy and regulatory trust.
Why it Matters
Reconciliation is fundamental to maintaining trust and regulatory compliance in financial operations. Without it, discrepancies between internal records and external accounts can accumulate rapidly, becoming increasingly difficult to resolve over time. For fintech companies, effective reconciliation serves multiple critical purposes:
