Q) Granger is a privately owned incorporated business that operates a garage which repairs and services motor vehicles. Most customers are required to pay by cash or cheque on collecting their vehicle. Credit accounts are available to business customers, These customers sign the invoice on collection of the vehicle and their business is billed monthly. Separate series of pre-numbered invoices are drawn up by the foreman for cash sales and for credit sales.

Cash sales

Collect cash or cheques from customers on collecting their vehicle. At the end of the day, check the numerical sequence of cash sales invoices, add the sales total and agree the total to the amount of cash and cheques received. Record the total cash sales in the cash receipts book.

Credit sales

Obtain the customer's signature on the copy invoice of business account customers. Enter the invoices in numerical sequence in the sales journal and post the customer's account in the accounts receivable ledger. Send monthly statements to credit account customers and follow up overdue accounts. List the balances on the accounts receivable ledger at the end of the month and reconcile the total with the control account in the general ledger. Write off uncollectible balances to bad debts.

Cash receipts

Open the mail, extract cheques from credit account customers, record them in the cash receipts book and post the accounts receivable ledger,
