Let me share some information about adding inventory assembly items, @Rosewood CC.
You can add up to 499 items to the Bill of Materials (BOM) when creating an inventory assembly.
You can create an inventory assembly to track your bill of materials from the Lists menu.
Here's more information on how to set up your product’s bill of materials. From here, you can use this item to start building your product.
Also, here's an article to learn more about the maximum number of list entries you can make in QuickBooks Desktop: Maximum number of list entries (list limits and custom fields).
For other concerns or follow-up questions, let me know by leaving a comment below. I'm always here to assist.
