If you offer services to your customers that they pay for in advance, you can track them on this tab. Prepaid services are set up as Non-Inventory Codes in Sales, and when you post sales that contain a prepaid service code, the information appears here. To adjust the quantity for any prepaid service, perform a type 8 transaction in the Enter Payments/Adjustments window.

If you selected the Show Prepaid Quantity Amount check box in Module Preferences, the quantity remaining will also appear in the top section of this window. The amount in the field in the top of the window is based on saved transactions, not posted transactions, so it might differ than the amount that appears in the Quantity field on this tab.
