Arcontica Classic Furniture (ACF) manufactures a range of rustic chairs, lawn furniture, and interior furnishing including lamps, desks, and bed frames. ACF's customer base comprises both private customers and retail outlets. Consumer's sales are for cash or by credit card, but business customers are for cash or by credit card, but business customers are extended a line of credit. New business customers undergo a credit check before receiving a credit line. All sales are made online, by fax or mailed in hard copy order. When a credit order is received, the sales clerk verifies inventory availability, prepares a sales order, and sends the stock release copy to the warehouse clerk who picks the goods and arranges shipment. He then prepares the bills of lading and sends copies of the shipping notices to the billing department and inventory control. The billing department updates the sales journal and sends an invoice to the customer. The clerk then sends the shipping notice to the AR department, where the AR clerk updates the AR subsidiary ledger. Customers submit checks and remittance advices to the mail room. A clerk sends the remittance advances to the AR department and the checks to the cash receipts department. At the end of the day, the cash receipts clerk prepares a deposit sip and deposits the checks into the company's bank account, files the bank receipt, and updates the cash receipts journal. The physical aspects of cash sales transactions are handled similar to the process described here except that checks or credit card account numbers are submitted with the original order.
