Bargain Family Company Limited ("BF") operates over 100 bargain shops in Hong Kong and the Mainland China selling general household merchandise. BF has a strong team who are very experienced in this industry and knowledgeable on cost management and financial planning. The success of BF has relied heavily on this sophisticated team. BF uses a self-developed point-of-sales ("POS") system, which is called "CheckOut," in all bargain shops. The management believes that an efficient system can serve the customers better. CheckOut was tested in prior years' audits with no significant deficiency from the information technology aspect reported. At every day end, the cashier reconciles the cash receipts of the day with the sales records in CheckOut. Each bargain shop is required to bank in its surplus cash by 10pm every day. At every month end, the accountant performs bank reconciliation. He reconciles the daily deposit to the bank statement. The last year's audit results indicated that the relevant controls in place on revenue were operated effectively throughout the year.

Another senior associate in the audit team considers that for these controls, it is not necessary to perform validation tests again in this year audit.
