You can create inventory assembly items in QuickBooks to track assembled goods that you produce, keep in inventory, and sell.
What is an inventory assembly item?
An inventory assembly item is one of the types of line items you can use when you are filling out a sales or purchase form. An assembly item lets you combine inventory part items and other assembly items (subassemblies) into a single item by defining a Bill of Materials, which lists the assembly item's component parts. You can also include the costs associated with building the assembly item by adding non-inventory part items, service items, and "other charge" items to the Bill of Materials.
Creating and adding assembly items to inventory is a two-step process. You first define the Bill of Materials that specifies what components go into making the assembly item, and then you build a certain quantity of the assembly item so QuickBooks can deduct the component parts from inventory and add new quantities of the assembled item. In other words, 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 assembly.

upgrade your edition of QuickBooks.
The following information is important for using inventory assembly items.
The two-step creation process for inventory assembly items
Creating an inventory assembly item is a two-step process. First, you create (define) the assembly item by listing what goes into the assembly. This list is called the Bill of Materials. When you define the assembly item, you also indicate how many of this assembly (if any) already exist in inventory.
After you define an assembly item, the way you add assembly items to inventory is by "building" them. An assembly build is necessary to keep your inventory quantities accurate. Each time you build an assembly item in QuickBooks, the inventory parts and other assembly items (subassemblies) in the Bill of Materials are deducted from inventory, and the assembly item's quantity is increased appropriately.
How QuickBooks tracks the cost of inventory assembly items
The cost of an inventory assembly item is calculated by adding together the cost of each item on the Bill of Materials. For inventory part items and inventory assembly items (subassemblies) on the Bill of Materials, the current average cost is used. The cost listed in the Bill of Materials is used for all other items.
Building vs. buying an inventory assembly item
Even though you create an inventory assembly item and normally build that assembly item yourself, there may be times when you need to buy it. In that case, the cost of the item is simply the price you paid for it.
What do I need to know about pending builds?
When you create a build and there are not enough of one or more inventory part items or inventory assembly items (subassemblies) to complete the build, you can mark the build as pending and then later, when you have enough inventory items, mark the build as final.
You can also mark a build as pending even if you have enough inventory on hand to complete it. This is useful for scheduling future builds and reserving the necessary inventory items until you're ready to complete the build. If you want to use pending builds in this way, make sure you set your inventory preferences to deduct inventory quantities on pending builds when showing available quantities.
Important: There are times when QuickBooks may change the status of a completed build from final to pending. That is because the ability to complete the build is directly tied to the build date and the inventory quantities available on that date. So if you change a transaction, such as an item receipt or bill, that reduces inventory levels on or before the build date, the build may be changed to pending status. We recommend you run the pending build report periodically to check if any completed builds were unintentionally changed to pending status. Once QuickBooks changes a build to pending status, you must manually change it back to final to make the assembly item quantities in QuickBooks inventory correct again.
Understanding the difference between an inventory assembly item and a group
You must have the Premier or Enterprise Solutions edition to create inventory assembly items. Learn how to upgrade your version of
Group items and inventory assembly items are similar in that they both let you record a group of items as a single entry on purchase or sales forms, but they also have some important differences.
Group items are useful for quickly entering a group of individual items that you often purchase or sell together.
Why use group items?
If you often enter the same group of items when you record a
sale or purchase, you can set up the items as a group item. Instead
of entering each item individually when you fill out a form, you
enter the name of the group item. QuickBooks then fills in the
details for the items in the group.
More reasons to use group items:
More detailed reports: Group items enable you to track the
items that you sell in greater detail. For example, a construction firm that
remodels houses could set up a group item that lists the significant components
of a remodeling job: lumber, carpentry hours, markup, and so on. Sales reports
for the company would then show income broken down by each component instead of
a single lump sum for all remodeling jobs.
Less detail for customers: If you need to track a lot of
detail about your items but you also want to give your customers simple,
uncluttered invoices, you can use group items to do both. You can set up a
group item so that the printed version of an invoice reduces a group item to a
single line item and one amount. Yet when you view the invoice on your screen,
you see a separate line entry and amount for each item in the group.
Fast data entry: Group items also give you a way to enter a
great amount of line item detail quickly. On a sales or purchase form, all you
do is enter the name of the group item—QuickBooks fills in all the
details about the items in the group.
Assembly items let you combine inventory items and assembly costs into new, separately trackable items that represent the finished goods you produce and sell.
Why use assembly items?
Track finished goods separately from individual inventory
items: When you build an assembly, an assembled unit is automatically
added to quantity on hand, and its component parts (inventory items or other
assembly items) are automatically deducted from quantity on hand. By using
assembly items, you always know how many assembled and component items you
actually have in stock.
Customize the price of assembled items: You can specify a
price for an assembly that's different from the sum of its component
Quick access to information about finished goods: You can
easily access the date that items were assembled, the quantity and cost of
assembled items, and a detailed list of component items.
Set reminders for future builds: You can set a build point,
and QuickBooks will remind you to build finished goods when stock is running
low. At build time, QuickBooks will verify that you have enough component items
in stock to build the specified number of assembly items.
The following table compares group and assembly items to help you decide
which item type is appropriate for your situation.

Quantity on hand of each item included in the group is adjusted in inventory

Quantity on hand of component items is adjusted in inventory when the

Sales tax is calculated by individual items included in the sales tax group item.

group, not the group itself.
QuickBooks tracks assembly items in inventory.
Price of a group item is the sum of the items in the group (although you can
include an item in the group for a discount or additional charge to adjust the
