Because Interface Codes deal with posting sales, revenue, accounts receivable, cash, and cost of goods sold, you will want to decide how you want to track these things. Posting for the following accounts can be controlled with Interface Codes:

When you create a Sales or Accounts Receivable transaction, Interface Keys that are attached to elements of the transaction create a combination known as the Interface Code. For example, a customer account might have the Interface Key CUST assigned to it, the Stock Item might have the Interface Key INV1, and the Sales Department might have the Interface Key DEPT1 assigned to it.

These Interface Keys are combined to determine the Interface Code and the Interface Code defines the accounts to which to post the amounts related to the sale. To put it another way, wherever an account is replaced by a GL Key, the Interface Code resulting from combining the GL Keys in the transaction will determine where the amounts will be posted.

The following Interface Keys combine to create the Interface Code. Interface Keys can be up to six alphanumeric characters and at least one character is required in every code.
