Growing manufacturers face a unique challenge with QuickBooks and bill of materials: QuickBooks doesn't fully support BOM management out of the box.
QuickBooks Desktop offers a basic single-level Inventory Assembly feature, but QuickBooks Online has no native BOM functionality at all.
The right software needs to handle multi-level product recipes, cost rollups, and production planning — and for most growing manufacturers, that means pairing QuickBooks with a dedicated BOM tool.
Sound familiar?
For many growing manufacturers, this scenario plays out far too often. At the heart of the problem is the lack of a proper Bill of Materials (BOM) system. QuickBooks is fantastic for managing your finances, but it wasn't designed to handle the complexities of manufacturing.
There's a way to make it work, though. Below, we'll cover what a BOM is, what QuickBooks can and can't do, and how to fill the gaps so your production floor runs smoothly.
What is a bill of materials (BOM)?
A Bill of Materials (BOM) is a document that lists all the raw materials, components, and instructions needed to manufacture a product. Think of it as your product's recipe. It's the backbone of any efficient manufacturing process, ensuring your team knows exactly what's needed to produce consistent, high-quality products.
For example, if you're a protein bar manufacturer, your BOM might include:
- Raw materials: Oats, whey protein, honey, cocoa nibs
- Packaging: Labels, foil wrappers, cartons
- Processes: Mixing, baking, cooling, sealing
Without a clear BOM, your team is left guessing. Mistakes become inevitable, timelines get derailed, and costs spiral out of control.
Why growing manufacturers need BOMs
For growing manufacturers, a BOM does more than list ingredients. It helps you:
Avoid costly production errors by giving your team a single source of truth.
- Maintain consistent product quality across batches.
- Forecast inventory needs to reduce stockouts and overstocking.
- Calculate accurate product costs, including raw materials, labor, and overhead.
- Scale operations without relying on tribal knowledge.

The short answer: it depends on which version of QuickBooks you're using. Here's how BOM support breaks down across the three main editions.
| Feature | QuickBooks Online | QuickBooks Desktop | QuickBooks Enterprise |
|---|---|---|---|
| Single-level BOM | No | Yes (Inventory Assembly) | Yes (Advanced Inventory) |
| Multi-level BOM | No | No | Limited |
| Cost rollup | No | Basic | Basic |
| Production planning | No | No | No |
| Real-time inventory tracking | Limited | Limited | Moderate |
| Best for | Accounting only | Simple assemblies | Larger single-level assemblies |
QuickBooks Online: no BOM support
If you're using QuickBooks Online, you won't find any native BOM functionality. There's no way to define an assembly, list its components, or track builds. You'll need to rely on manual workarounds like spreadsheets — which are prone to errors and impossible to scale.
This is a common pain point. Many manufacturers start on QuickBooks Online for its convenience, then realize they need a separate system once production complexity grows.
QuickBooks Desktop: basic inventory assemblies
QuickBooks Desktop offers an "Inventory Assembly" feature that lets you define a finished product and its components. You can build assemblies, and QuickBooks will deduct the component quantities from inventory.
However, it's limited:
No multi-level BOMs. If your finished product contains a sub-assembly (for example, a pre-mixed sauce that goes into a final product), QuickBooks Desktop can't handle that nesting.
No production scheduling. You can't plan when to build or allocate resources.
No real-time tracking. Inventory updates happen after the fact, not during production.
QuickBooks Enterprise: a step up, but still limited
QuickBooks Enterprise with Advanced Inventory adds features like bin tracking, serial numbers, and FIFO costing. It handles inventory assemblies better than Desktop, but it still lacks true MRP functionality — no production scheduling, no purchase order automation based on demand, and no multi-level BOM explosion.
For manufacturers doing $500K–$50M in revenue who need to plan production runs, manage complex recipes, and track materials in real time, QuickBooks alone isn't enough.
How to use bill of materials for inventory management
A BOM isn't just a production document — it's the foundation of your entire inventory management process. When your BOMs are accurate and connected to your inventory system, several things become possible.
Accurate demand forecasting
Your BOM tells you exactly how much of each raw material you need per unit of finished product. Multiply that by your sales forecast, and you have a clear picture of what to order and when. No more guessing.
For example, if your BOM says each batch of granola bars requires 50 lbs of oats, and you plan to produce 20 batches this month, you know you need 1,000 lbs of oats — before you run out.
Automated reorder points
With BOM data feeding your inventory system, you can set reorder points for every raw material. When stock drops below the threshold, a purchase order gets triggered automatically. This is especially valuable for food and beverage manufacturers managing perishable ingredients with limited shelf life.
Accurate product costing
Your BOM defines every input that goes into a product. When each of those inputs has a cost attached, you can roll up the total manufacturing cost per unit — materials, labor, and overhead. That's the kind of visibility QuickBooks alone can't give you.
Reducing waste and overstock
When BOMs are managed in spreadsheets, purchasing teams tend to over-order "just in case." A proper BOM system tied to inventory data eliminates that guesswork. You buy what you need, when you need it.
Can you manage BOMs online?
Yes — and for most growing manufacturers, a cloud-based BOM management tool is the best option. Online BOM software gives you:
Access from anywhere. Your production team, purchasing team, and management can all view the same BOMs in real time.
Automatic updates. When you change a recipe or swap a supplier, the update is reflected immediately.
Version control. Track changes over time so you know exactly what was in each version of your product.
Integration with accounting. Cloud BOM tools typically connect with QuickBooks Online or Desktop, keeping your financial data in sync.
This is especially relevant if you've outgrown QuickBooks Desktop and moved to QuickBooks Online, where there's no built-in BOM feature at all. A cloud-based BOM and MRP platform fills that gap without forcing you off QuickBooks for accounting.

The problem: why QuickBooks alone isn't enough for manufacturing
QuickBooks excels at what it was designed for — accounting, invoicing, payroll, and financial reporting. But manufacturing requires a different set of tools.
Here's where the friction shows up:
No production planning. QuickBooks can't tell you what to produce, when to produce it, or whether you have enough materials on hand. You need production planning software for that.
No MRP logic. Material requirements planning — calculating what to buy based on what you need to build — doesn't exist in QuickBooks.
No lot tracking. If you're in a regulated industry (food, supplements, cosmetics), you need forward and backward traceability. QuickBooks doesn't offer lot tracking.
No multi-level BOMs. Complex products with sub-assemblies require BOM nesting that QuickBooks can't handle.
Relying on QuickBooks alone can lead to missed deadlines, inventory mismatches, and frustrated teams. The good news is that you don't have to replace QuickBooks — you just need to pair it with a purpose-built manufacturing system.

Frequently asked questions
Does QuickBooks do bill of materials?
QuickBooks Desktop and QuickBooks Enterprise offer a basic Inventory Assembly feature that supports single-level BOMs. QuickBooks Online has no native BOM functionality. For multi-level BOMs, production planning, or MRP, you'll need a dedicated manufacturing platform that integrates with QuickBooks.
What is BOM data entry?
BOM data entry is the process of inputting your product's components, quantities, units of measure, and assembly instructions into a software system. Accurate BOM data entry ensures your inventory counts, cost calculations, and production plans are all based on the correct recipe. Most manufacturers start with manual entry and eventually import BOMs from spreadsheets into a dedicated BOM tool.
Can you use QuickBooks Online for manufacturing?
QuickBooks Online handles accounting, invoicing, and basic inventory counts, but it lacks manufacturing-specific features like BOMs, production scheduling, MRP, and lot tracking. Growing manufacturers typically keep QuickBooks Online for financials and add a cloud-based manufacturing platform for operations.
What is the difference between a single-level and multi-level BOM?
A single-level BOM lists only the direct components of a finished product — one layer deep. A multi-level BOM includes sub-assemblies and their components, creating a nested structure. For example, a single-level BOM for a bottled sauce might list "sauce" and "bottle." A multi-level BOM would also break down the sauce into its individual ingredients. QuickBooks only supports single-level BOMs.
How Brahmin Solutions works with QuickBooks
The core problem this article identifies — QuickBooks only supports single-level assemblies — is exactly what Brahmin was designed to solve. QuickBooks is excellent accounting software, but it was never built for manufacturing. You can't create multi-level bills of materials, can't manage sub-assemblies, can't version BOMs when engineering changes happen, and can't automatically roll up costs across multiple levels of a product tree.
Brahmin adds the full BOM layer that QuickBooks lacks. You define multi-level bills of materials with sub-assemblies, variants, and configurable components. When you change a BOM — swapping a material, adjusting a quantity, adding a new sub-assembly — Brahmin tracks the revision history and automatically recalculates costs at every level. The cost rollup flows from raw materials through sub-assemblies to finished goods without manual calculation.
Here's the important part: Brahmin syncs with QuickBooks, so you keep your books where they are. Product costs, inventory values, purchase orders, and sales orders flow between the two systems. You're not replacing QuickBooks — you're adding the manufacturing capabilities it was never designed to have. Starting at $199/month with unlimited users, and most manufacturers are live in 3-6 weeks. Book a demo and bring a product with a multi-level BOM — we'll build it in the system live.
