In QuickBooks an inventory assembly item is a specific type of Item that is the result of putting together a new inventory part out of a bundle of individual items to enable tracking finished goods separately from individual components. Normally, an inventory assembly item is used when separate raw materials are assembled, packaged, and sold as an inventory item that is separate from the component parts.
See our article on all of the Item types supported by QuickBooks for more information.
The inventory assembly item type is only available in QuickBooks Premier and Enterprise Solutions. It’s not available in QuickBooks Pro.
It is similar to – but different from – a group item, another approach to managing a bundle of individual items. A group item is a way to quickly add a bundle of items to a form while preserving the ability to track those items individually. Where an inventory assembly item functions like a pre-assembled kit, a group item functions like an “on the fly” kit.
An inventory assembly item is made up of a Bill of Materials (visible by clicking the Full View… button) which can contain a range of item types: service, inventory part, another inventory assembly, non-inventory part, and other charge. Note that a subassembly can be nested within an inventory assembly. However, the Bill of Materials cannot contain these item types: subtotal, group, discount, payment, sales tax item, or sales tax group. Further, there’s a limit of 100 items in the Bill of Materials for an inventory assembly in QuickBooks Premier; for Enterprise Solutions, that limit is 500 items.
The Cost shown for an inventory assembly item should normally not be entered. When a Cost is not entered, QuickBooks will use the Bill of Materials Cost that appears at the bottom of the table.
An inventory assembly is built from its components parts by clicking on the Vendors->Inventory Activities->Build Assemblies menu selection. During the build process, the Quantity on Hand of the inventory assembly item is increased by the Quantity to Build, and the Quantity on Hand of each component is reduced by the product of that item’s Qty in the Bill of Materials and the Quantity to Build.
Builds in QuickBooks can be either pending or final. If there are insufficient quantities of the component parts, a build will automatically be marked as Pending. You can also manually mark a build as pending by clicking on the Edit->Mark Build As Pending menu selection while the Build Assemblies window is displayed. The Pending Builds report (Reports->Inventory->Pending Builds) supports managing future build requirements.
Here’s an example of invoicing for the inventory assembly item Interior Door kit shown above. Unlike a group item, which automatically adds other items to a form and controls whether these other items are printed, the inventory assembly item appears as a single line item on a form.
The price of an inventory assembly item is specified, just like the price of an inventory item, and can be changed directly on a form.
Sales tax for an inventory assembly item is calculated based on the single Tax Code assigned to the inventory assembly.
