A proof of cash is used to reconcile the cash receipts and disbursements recorded on the client’s books with the cash deposited into and disbursed from the client’s bank account for a specific time period. The purposes of the proof of cash are to ensure:
(a) All cash receipts recorded in the client’s accounting records were deposited in the client’s bank account.
(b) All cash payments recorded in the client’s accounting records have been cleared.
(c) No bank transactions have been omitted from the client’s accounting records.
6.2.2 However, a proof of cash cannot detect a theft of cash when the cash was stolen before being recorded in the client’s books. If the auditor suspects that cash was stolen before being recorded in the client’s books, the audit procedures for testing the completeness in recording cash receipt transactions should be performed.
