Purchase Discount

Suppliers grant percentage or fixed discounts, but standard purchase orders have no discount column. This module adds line discounts and a global discount on the order with a type selector. Totals show the amount before discount and the discount amount, and the discount carries to vendor bill lines and stock cost. It is used by purchasing and accounting and plugs into Purchase, Inventory and Accounting.
