When making and estimate for a Product made up of multiple items, the TOP LINE MUST HAVE A QUANTITY ENTRY, AND A DESCRIPTION OF THE PRODUCT. The other lines (sub-item lines) can be completed fully, be blank, or contain information only in the Description field. When you make an entry in a sub-item quantity block, enter the number of sub-items needed to make up one top line Product. Enter the price for one sub-item. The price and sub-item quantity will be multiplied to get the total cost for each sub-item. The sub-item price and sub-item cost will show on the screen, but they won't print on estimates or invoices. The cost of all sub-items will be totaled and added to the top line as the price for one-complete-product. That price will be multiplied by the quantity to get the total cost of all Products. The top line price and the total cost of all Products will print on estimates and invoices. Press Enter to continue.
