The Build-to plugin saves a pre-seller a considerable amount of time while entering orders using a handheld. Within eoStar, desired inventory quantities can be entered for each product. When a pre-seller enters a count for a customer via their handheld, the appropriate field will suggest an order quantity by using the build-to value that was entered for the product. For example, if the build-to value for product # 8764 is 5 and the customer has a count of 3, then the quantity field will be populated with a suggested order quantity of 2 when the Auto-Calc QTY menu option is selected. The suggested order quantity can be overridden.
