1) The audit work papers contain the following narrative description of the cash sales procedures of a retail clothing store. All sales are for cash; no credit cards are accepted. Each individual sale is rung up by the sales clerk on a cash register that ejects a sales slip. The sales slip is given to the customer, and a copy of the sales slip is made by the cash register on a continuous tape locked inside the machine. At the end of the day, the sales clerk presses a total key and the machine prints the total sales for the day on the continuous tape. The clerk then unlocks the cash register, removes the day's tape, makes an entry in the cash receipts book, counts the cash in the drawer, retains a change fund of $100, and turns the rest of the cash over to the cashier. The sales clerk then files the cash register tape and is ready for the next day. Required: Provide four recommendations to improve controls over cash sales. 2) The following are situations that an auditor might encounter as a result of applying year end substantive tests to accounts receivable as at 30 June 2020. a) Balances in selected individual customer accounts do not reconcile with supporting documentation. b) Sales totalling $25,000 were shipped on 2 July 2020 and recorded on 30 June 2020. c) The aged trial balance prepared by the client includes a customer account within the 30- to 60-day category that is actually 120 days old. d) Not all sales transactions are recorded. e) Actual write-offs during 2020 of receivables arising from 2019/2020 sales were greater than the 30 June 2020 allowance for doubtful accounts. f) Positive confirmations were not returned by 30 of 100 mailed receivables confirmations.
