The Interface Codes function in a similar fashion in Accounts Receivable transactions except the third position (sales department) is not used and the cost of goods sold account is not used.

You might use Interface Codes in Accounts Receivable because you want to track the discounts customers are getting as a result of the terms you’ve set up for them.

Accounts Receivable Interface Codes only require two GL Keys; one GL Key is attached to the customers and the other is for any cash or non-customer transactions. The customer is the first position and the Terms Code GL Key or the AR Transaction Code GL Key is the second position.

The Interface Codes list for accounts receivable is much shorter than the list for sales. However, even though fewer variables keep it smaller and simpler, it can also be made larger if necessary.

The following list of Interface Codes would allow you to specify transactions for each transaction option. However, you could expand on this.
