Adirondacks Classic Furniture (ACF) manufactures a range of rustic chairs, lawn furniture, and interior furnishing
including lamps, desks, and bedframes. ACF's customer base comprises both private consumers and retail outlets.
Consumer's sales 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 compy to the warehouse clerk who picks the goods and arranges shipment. He then prepares the
bill 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 advices 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 slip 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 similary to the process described here except that
checkss or credit care account numbers are submitted with the original order.
