its the answer for the first one but you can use it as an example to answer the others.

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

1) inventory

2) The main potential error that is targeted by this procedure is the accuracy of the sales making sure that the packing ships match the sales invoice and that they are all properly recorded and none are missing

3) If there was an error between the shipping document and the invoice it could affect the sales and inventory count. Furthermore, the company could have the incentive to not properly record the sales so as to not pay taxes.

4) Completeness because you are verifying that all packing slips have a sales invoice and all sales transactions are documented.

• identify the main account or class of transactions that is involved[1]
• 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)

My main goal is that you become familiar with assertions and see how the auditor choose audit procedures. Dont think that auditor will test everything with the same weight, it is more strategic than that. If he/she considers that the manager is being pressured to hide debts, the completeness of debts will be considered more important than their existence and tests will be designed accordingly.

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

Early February: the auditor started the process by making sure that amounts presented in the FS correspond to the balances in the General Ledger as of December 31 and, as a second step, that these balances correspond to totals of journals, subledgers, lists, etc. that give the details of the accounts. There was no error and, so, the auditor can use these documents for testing.

1) Draw a sample of shipping documents and examine each one to make sure that a duplicate sales invoice[1] 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

6) Obtain the bank statement for January, select a sample of payments made to suppliers, trace suppliers invoices and compare to individual accounts payable

7) Obtain the invoice for municipal taxes and redo calculation of Prepaid expenses

8) Obtain the list of suppliers that the entity normally does business with, identify the ones with a zero balance on year-end and mail a letter asking for a confirmation

9) Visit the clients warehouse, select a few items from the shelves and check if they appear on the inventory list

10) Visit the clients warehouse, select a few items from the inventory list and check if they are on the shelves

11) Go around the clients warehouse and observe if some items are in a bad condition (broken, dusty, etc.)

12) Select a few sales invoices and redo the calculation of the total and sales taxes

[1] The original sales invoices were given to customers
