You will find on the next page a series of audit procedures. For each one, I ask you to:

• identify the main account or class of transactions that is involved
• describe the main potential error that is targeted by this procedure
• identify the main consequence that such error would have on the FS
• identify the most relevant audit assertion that is involved (if you identify more than one assertion, I will consider only the first as the most relevant)

1) Draw a sample of shipping documents and examine each one to make sure that a duplicate sales invoice is attached.

2) Draw a sample of duplicate sales invoices and examine each one to make sure that a shipping document is attached

3) Obtain an aging of accounts receivables and compare with managers estimation of the Allowance for doubtful accounts

4) Draw a sample of receiving reports and compare dates with suppliers invoices and the acquisitions journal

5) Select a sample of accounts receivable balances from the accounts receivable subledger and mail a letter to each selected customer asking them to confirm the balance

[1] With double-entry accounting, you can always identify a second account. Audit procedures aim at a precise account or class of transactions though.
