Account Closure is the process by which an existing bank account or facility is closed after repayment, transfer, settlement, or internal decision. For balance transfer cases, it is used to verify that the old lender’s exposure is extinguished. Capture closure date, closure proof, and pending dues where applicable. In MSME credit workflows, it mainly supports clean account mapping, workflow routing, audit trails, reporting and post-disbursement servicing rather than acting as a standalone credit-strength indicator. For example, if the value is captured incorrectly in the loan-origination system, approvals, account mapping, reporting or customer servicing may later fail even when the credit decision is sound. It matters because the credit, operations and monitoring teams must all work from the same borrower, facility and account record. The common mistake is to treat it casually as a back-office field; wrong, duplicate or unmasked data can create privacy risk, reconciliation errors and avoidable rework.
