Narrative:

The Lansdowne Company operates stores at many locations throughout New England. The company's headquarters are in Boston. The company accepts cash and its own Lansdowne charge card (LCC). LCC billing and the treasury function are located at headquarters.

All cash receipts from the company's proprietary charge cards (LCCs) are received in Boston at the cash receipts section. The company uses a turnaround document, so the company receives a check and a portion of the monthly LCC statement (on which the customer has filled in the amount remitted). The cash receipts clerk compares the check to the amount written on the document, and, in a space reserved, enters on the document the amount received so that it can be computer scanned.

Checks and turnaround documents are batched. The documents are sent to data processing. The cash receipts clerk prepares the deposit slip, photocopies the deposit slip (two copies made), and deposits the checks with a copy of the deposit slips to the bank. The batch totals and the deposit slips are filed separately by date. A copy of the deposit slip is sent to the treasurer's office.

Data processing uses an optical scanner to process the turnaround documents. The scanner is online and reads the turnaround documents directly into the computer. This run occurs each evening at 10:00 p.m. Customer's accounts are posted, and a cash receipts listing is produced and is sent to cash receipts each morning, where it is checked against and filed with the related batch totals. A copy of the cash receipts listing is sent from the computer to the treasurer's office.
