The accounting system and internal controls were reviewed, and the audit completed within the time frame of two weeks.   At the commencement of the audit the following accounting systems were recorded.   (a).  Income Recognition  Income is recognised by the client based on the amount in the sales invoices issued for the goods supplied. The amounts of the sales orders are recognised as income for all the pending suppliers as at 31 December of each year. Commissions are paid to the sales executives in the first week of January following the year end. This is based on the turnover figure in the management accounts prepared by the chief accountant before the year-end audit is done by the external auditors.   (b)  Salary Payment  Staff salaries are prepared in a register maintained by the accountant from where the salary summary sheet is prepared and submitted to the chief accountant for approval. The cashier subsequently withdraws cash needed for the salary payment and pays the staff members Staff members are not required to sign for the payment. This is because Management believes that the payment process is witnessed by another staff  from the  sales department  At the end of the payment , the cashier  stamps  the salary  summary sheets  with “Paid Stamp” as evidence  of  the salary payment.  (c). Directors’ Drawings  The Chief Accountant gives approval for personal drawings requested by the Directors based on the telephone discussion with the Director. No drawings account is maintained for each of the directors in the general ledger. The accountant only has the consolidated outstanding balance in the Directors’ Drawings account without showing the amount drawn by each of the Directors.  The engagement partner discovered during his review of the audit file that the following adjustments were passed by the audit manager which made some of the  figures  in the drafts accounts  to be  different  from those  of the management  accounts  prepared  by the client.  (i).

(d). The managing director disagreed with the firm on the above audit journals passed and gave the following reasons to support his argument.  (i).  The turnover of £250,000 that was adjusted represented the sales orders received on 30 December 2019 for new supplies to be made in the following year. He said that their decision to recognise the amount as income in the year 2019 was to help the company reach a turnover benchmark of £1million required to completely bid for government contacts.  He also said that commission on sales has been paid to the sales executives on the basis of the turnover  of £1million  disclosed  in the management  accounts .   (ii).  Staff salaries of £24,000 was included in the cost of sales so as to reduce the  PAYE tax to be paid by the company.   (iii).
