An amount mismatch is a reconciliation exception where two entries that likely represent the same transaction show different amounts in the two files being reconciled.
An amount mismatch occurs when two candidate entries — which appear to represent the same financial event based on date, reference, and party — show different amounts across the two files. Common causes include processing fees deducted from one side, currency conversion differences, rounding, partial payments, tax treatment differences, and data entry errors. Amount mismatches require investigation to determine the source of the difference and whether an adjustment is needed.
Amount mismatches can signal errors in either file, unexpected fee deductions, partial payment situations, or currency conversion issues. Left unresolved, they can cause reconciled balances to appear accurate while underlying amounts are incorrect.
A supplier invoice in the payables ledger shows $10,200. The bank statement shows a debit of $9,996. The difference is $204 — which investigation reveals was a prompt-payment discount applied by the supplier that was not reflected in the original invoice.
