This field is on the Main tab of the Customer Maintenance window.
(Optional) You can keep track of your Account codes in the Code Maintenance window, accessible from the Tools menu in Customer Maintenance.
Use the Account Codes field to categorize customers. You can use the codes to include or exclude accounts on reports.
For example:
Assign a code of P to all of your paint contractors. Then you can run sales analysis reports for those accounts to determine the profit margin for that customer group.
Assign a code of T to all your transfer accounts. Then you can exclude them from the reports you run for your regular charge accounts.
This field is alphanumeric. You can enter a combination of up to four letters and numbers. Each position of the field is independent of the other positions. For example, _P__ is not the same as P___.
