Bank reconciliation explained: how to know your books match the bank

A bank reconciliation is not the same as downloading bank transactions into accounting software. It demonstrates that the ending cash balance in the books can be reconciled to the ending balance on the bank statement after legitimate timing differences are identified.

Use the bank's official monthly statement, not a live online balance that changes during the day. Confirm the opening balance agrees to the prior reconciliation, match cleared deposits and withdrawals, identify outstanding items, and investigate transactions that exist on one side but not the other.

A suspense or reconciliation adjustment can hide the very problem the process is meant to identify. If the bank and ledger differ, find the cause, document the treatment, and leave unresolved items on an exception list with an owner.

Keep the bank statement, reconciliation report, and support for material reconciling items with the monthly close. That turns the cash number from 'what the software says' into a balance another reviewer can independently verify.

Complete the reconciliation on a predictable schedule and assign a reviewer when the business needs separation between preparation and approval. Repeated exceptions should become process fixes: a duplicate bank-feed rule should be corrected, a processor clearing account should have a defined settlement workflow, and transfers should use consistent counterpart accounts.

Watch old outstanding items. A payment or deposit that remains unresolved for several periods may no longer be a normal timing difference and should be investigated. Keep notes for material reconciling items so the next month's preparer knows whether the balance is expected to clear or needs action.

The same discipline extends beyond cash. Credit cards, payment processors, loans, payroll liabilities, receivables, and other balance-sheet accounts need their own source-to-ledger reconciliations when they are material to the business.
