Now that sales departments have been specified, you might want to identify new customers according to the department they are introduced in and then post all the revenue accordingly. Now you are posting transactions depending on the item selected or sold, the department it is sold in, and the customer.

As a result, a single stock item could post to ten different sales accounts depending on where it is sold, if it is sold as cash or to a customer charging to their account, who the customer is, and what category the stock item is in.
