Buyers management allows you to generate a shopping list while viewing MIN & MAX requirements. SBI lets you set min and max by dates so that you can carry high quantities during the right eason for that product and let it drop to minimum when it is out of season. Also view previous sales history and margin of that product. After generating the shopping list then efficiently broadcast fax and email price and availability requests from vendors who had it in the past. System shows all purchase history from vendors in the past so you can make quick decisions on who to try first. As you get confirmation on pricing and availability generate POs and whittle away that shopping list as you generate POs by vendor. Nothing is more efficient for managing purchasing.
