An Inventory Assembly item is one type of line items used when creating a sale or purchase form. Creating and adding assembly items to inventory is a two-step process:
- First, define the Bill of Materials (BOM) to specify what components go into making the assembly item, then build a quantity of the assembly item so QuickBooks Desktop can deduct the component parts from the inventory and add new quantities of the assembled item.
Note: As soon as you build an assembly item, its component parts no longer exist as separate parts in inventory because they have become part of a new inventory item called an inventory assembly.
- After assembly items are defined, they are added to inventory by "building" them. An assembly build is necessary to keep inventory quantities accurate.
Note: Each time an assembly item is built in QuickBooks Desktop, the inventory parts and other assembly items (sub-assemblies) in the BOM are deducted from inventory, and the quantity of the assembly item increases.
