Bank reconciliation

The process of matching every line on a bank statement to a corresponding record in the accounting software — an invoice, bill, or journal entry — so that the bank balance and the books agree to the penny.

Also: reconciling, reconciliation

Bank reconciliation is the bookkeeping checkpoint that confirms your records match reality. You take each line from your bank statement — a supplier payment, a customer receipt, a bank charge — and find (or create) the matching entry on the other side of the ledger. When every line is accounted for, the bank balance in your software equals the balance the bank reports, and reconciliation is complete.

In Xero, this happens on the Reconcile tab. Xero pulls transactions from your bank via a live bank feed, then suggests matches against open invoices and bills. Simple cases — a single payment for a single invoice — resolve in one click. More complex cases require judgement: a £3,750 receipt that part-pays two invoices and leaves £250 as a prepayment needs four separate postings before the line will clear.

Why it matters at month-end

Reconciliation is the gate before any other month-end task. An unreconciled balance means your profit and loss and balance sheet figures are unreliable, VAT totals may be wrong, and aged debtors or creditors may be overstated. Most accountants will not sign off management accounts until the bank is fully reconciled. Done weekly rather than monthly, it reduces the pile-up and surfaces errors — a duplicate payment, a missed direct debit — while the detail is still fresh.
