I'll share details about the inventory builds in QuickBooks Desktop (QBDT), Mark.
When setting up inventory assembly, COGS will show as $0. The part costs won't add up to the finished build cost. This is because the program will recognize it as a new item. You have to manually enter the cost of the assembly.
The same goes with classes. Parts that are assigned to assembly won't automatically assigned to the same class. You still have to select the class appropriate to this build.
Additionally, you can assign the class to an inventory item by modifying the preferences in the Company Preferences menu. Here's how:
- Go to the Preferences menu by clicking the Edit tab.
- Next, click the Accounting tab and select Company Preferences.
- In the Class section, check the Use class tracking for transactions box.
- Then, check Assign classes to and select Items.
- Click OK.
For reference, read this article: Combine your inventory items to build finished goods (assemblies).
I also suggest reaching out to your accountant for additional guidance in managing your build assembly.
