Bank reconciliation

Definition

A bank reconciliation is the process of matching a business's own cash records to its bank statement, identifying any differences — uncleared payments, unrecorded charges, errors — so the two agree. It is a basic control that keeps your cash figures trustworthy.

In plain terms

Timing differences (a cheque not yet cleared) and omissions (a bank fee not yet booked) cause the two to diverge. Reconciling regularly catches errors, fraud and forgotten transactions before they distort your view of cash.

Why it matters

You cannot manage cash you cannot measure accurately, and reconciliation is what keeps the measurement honest. See how to reconcile your bank account.

In practice

For a small UK limited company, bank reconciliation usually happens after the bookkeeper or director pulls the latest bank statement and lines it up against the cashbook or accounting software. Each entry is checked off: sales receipts, supplier payments, direct debits, standing orders. Anything on the statement that has not been recorded gets added; anything recorded that has not yet appeared, a cheque paid out but not yet presented for example, is flagged as an outstanding item rather than treated as missing money.

Where a difference cannot be explained by timing alone, that is the signal to dig further rather than force the numbers to match. It might be a duplicated entry, a payment posted to the wrong account, or a transaction the business genuinely was not aware of. Directors of growing companies often find this discipline becomes harder to sustain informally once transaction volume rises, which is usually the point at which a fixed monthly reconciliation routine gets introduced rather than doing it only when something looks wrong.

Common pitfalls

The most frequent slip is treating reconciliation as an occasional tidy-up rather than a routine check, which lets small discrepancies accumulate and become harder to trace back to their source. A related pitfall is reconciling against a statement that is already out of date by the time it is checked, rather than working from the current live balance.

Another common issue is adjusting the cashbook to match the bank figure without establishing why they differed in the first place, which can mask genuine errors, duplicate payments or unauthorised transactions rather than surface them. Keeping a clear log of outstanding items from one reconciliation to the next, and following up anything that stays unexplained for more than one cycle, is generally regarded as good practice.
