Jenna is working on the audit of a clients accounts receivable. During the last few weeks she has conducted interviews with the accounts receivable manager, the chief financial officer and staff working in the accounts receivable department. She has also overseen the external confirmations of accounts receivable, 30 per cent of which required the recipient to respond whether or not the amount stated was correct. Jenna also conducted a review of subsequent cash receipts from the clients customers. She vouched a sample of accounts receivable balances back to the underlying invoices, cash receipts and sales returns, and traced a sample of these documents to the accounts receivable ledger.
