This program will be used to enter all orders and sales to customers.

An invoice may be entered directly or an order may be created and then later used to create one or more invoices as lines from the order are satisfied.

There will be two main styles for entry;  If the sale is for a  customer who has an in house accounts receivable charge account then that customer will be identified from the customer file;  If this is a cash or credit card type of sale then the operator will first search the mailing list file to see if this customer is already on file, or more likely, the name and address will be added to the list at this time.
