Suspense account
A suspense account is a temporary holding account used to park a transaction when it cannot immediately be allocated to the correct nominal code — keeping the books in balance while the right treatment is worked out.
A suspense account acts as a waiting room in your chart of accounts. When money arrives or leaves the bank and you are not yet certain how to categorise it — perhaps a £1,200 payment with no remittance advice, or a bank line that does not match any open invoice — posting it to suspense keeps your double-entry intact without forcing a premature decision on the nominal code.
How it works in practice
Suppose £950 lands in your business account with the reference “Settlement — see email”. You cannot immediately match it to an invoice, so you reconcile the bank line to a suspense account rather than leaving it unreconciled. The books balance and month-end can proceed. Once you identify the payment as a partial settlement against two invoices, you raise a manual journal to move the £950 out of suspense and allocate it correctly: say £600 to Invoice 1042 and £350 to Invoice 1043.
A well-managed suspense account clears to zero before every month-end close. An account with a persistent balance is a warning sign: it may mean unresolved bank lines, misposted transactions, or a reconciliation that was closed prematurely. Accountants typically review the suspense account as one of their first checks when preparing year-end adjustments.
