How a Bill of Materials Software Improves BOM Management

Many QuickBooks Online users manage bills of materials with separate spreadsheets. This approach often leads to errors that make it difficult to understand true production costs. With bill of materials software that integrates with QuickBooks online, you can define components, quantities, and build requirements in the same place you keep inventory and production data. 

Keep reading to learn how you can get a clearer view of material usage, costs, and build activity by extending QuickBooks Online with SOS Inventory’s inventory management software.

Why Is an Accurate BOM Important for Manufacturers?

An accurate bill of materials is the foundation of your production process. It defines what goes into each product, how much of each component you need, and how those materials flow through your operation. When this information is reliable, you can plan, build, and track production with confidence. When it isn’t, small inconsistencies quickly turn into larger operational issues.

Accurate BOM supports:

• Inventory accuracy – Raw materials and finished goods stay aligned with actual production activity. 
• Cost control – Product costs reflect real material usage, so you can make better pricing decisions.
• Production efficiency – Your team can follow the same structure every time, making production more predictable and repeatable.
• Scalability – Consistent workflows will keep your operation organized as order volume increases.

Why Do Spreadsheets Fall Short for BOM Management?

Spreadsheets often work as a starting point for managing bills of materials, but they become harder to rely on as your operation grows. Every change in quantity or materials relies on someone updating the sheet. Over time, multiple versions can exist, and it becomes unclear which one reflects current production requirements. There is no real-time connection between your BOM spreadsheet and stock levels, so material usage is not automatically reflected in your inventory records.

These limitations create measurable risk. You can’t maintain accurate inventory records when material consumption is not tracked consistently, and you can’t understand product costs with outdated BOM data. Production delays are more likely to occur when builds are based on incorrect or inconsistent information.

In contrast with bill of materials software, spreadsheets

• Do not automatically adjust inventory counts based on builds
• Do not connect to real-time build activity
• Make it difficult to scale across multiple teams or locations

How Does Bill of Materials Software Improve BOM Management?

While QuickBooks Online handles accounting well, it cannot define how components, builds, and inventory interact during production. Bill of materials software like SOS Inventory provides that missing layer by connecting your BOMs directly to inventory and build activity.

Here’s how:

1. Structured BOM Reports

BOMs are stored as an extension to assemblies—not spreadsheets—with standardized components, quantities, and relationships.

2. Automated Inventory Tracking

Bill of materials software automatically reduces raw materials counts and increases finished goods counts as production occurs. Inventory levels align with actual activity without manual updates.

3. Centralized Production Visibility

Build activity is tracked in a single system, giving you a clear view of what’s been built, what’s in progress, and how production is moving.

4. Scalable Workflows

With repeatable production processes that update automatically, you get a more consistent, organized approach to BOM management that supports business at scale.
