The most important duties that should be segregated in the sales and collection cycle are::
Receiving orders for sales
Granting credit (credit approval)
Shipping goods
Maintaining inventory records
Billing customers and recording sales
Maintaining general accounting records
Maintaining detailed accounts receivable records
Processing cash receipts
Pursuing unpaid accounts
Segregation of duties should be used extensively in the sales and collection cycle for two reasons. First, cash receipts are subject to easy manipulation. second, the large number and nature of transactions within the cycle make the procedure of cross-checking, where one employees duties automatically serve to verify the accuracy of anothers, highly desirable.
