Custom bill of materials (BOM) software development
Appfront builds custom bill of materials (BOM) software for manufacturing: multi-level bills of materials, item and material management, revisions and version control, and integration with procurement, inventory and costing. This page focuses specifically on product structure, not planning. For planning, see our production planning software. This way you keep full control over exactly what your product is made of, down to the smallest part.
What is bill of materials (BOM) software?
A bill of materials (BOM) describes which components, semi-finished products and materials a product is made of, and in what quantities. BOM software manages that structure, often across multiple levels, so that an assembled product refers to subassemblies which in turn consist of components. It is the backbone of any manufacturing administration.
In standard packages, the bill of materials is often rigid or subordinate to planning. With custom software, the structure fits your products, your revision logic and the way you calculate costs and purchase. If a component changes, the change is carried through in a controlled way to all products in which it appears.
This page focuses on product structure. For planning and scheduling orders, see production planning software, and for the broader context, see software for the manufacturing industry.
Multi-level structure
Products, subassemblies, components and materials in a nested bill of materials. You expand each level and see exactly where a component is used and in what quantities.
Revisions under control
Every change to a bill of materials is recorded as a revision, with history. This way you know which version went into production and can revert to an earlier state.
From BOM to procurement
The bill of materials flows through to material requirements, so procurement and inventory know what is needed. Duplicate lists and overlooked errors disappear.
How we build your bill of materials software
We work step by step and involve your production preparation, engineering and procurement early in the process. From an exploration of your product structure and revision logic through to go-live and maintenance, every step is aimed at software your team can trust.
We map out your product structure: how your bills of materials are built, how you manage revisions, how you cost, and which integrations with procurement, inventory and CAD are needed.
We design the item and BOM model, the revision logic and the calculation rules for material requirements and costing, with a workflow that suits engineering and production preparation.
We build in short iterations with working interim versions. You test the BOM logic against real products, so the software matches your practice.
Controlled go-live with migration of existing bills of materials and parts, followed by ongoing management and further development.
What bill of materials software actually does
We tailor every application to your products and processes. Below are the features we most often deliver for BOM management in manufacturing.
Multi-level bills of materials
Management of nested bills of materials with unlimited levels, where subassemblies can be reused across multiple end products and quantities are calculated automatically.
Parts and materials management
A central parts register covering components, materials, suppliers and units, so every item is unambiguous and used consistently throughout.
Review and version control
Every change is recorded with revision number, date and reason, so you always know which version is valid and which has gone into production.
Where-used analysis
See at a glance in which products and subassemblies a component appears, so the impact of a change or phase-out is clear in advance.
Material requirements and costing
Calculate the required materials and cost price per product from the bill of materials, using current purchase prices and standard times where you record them.
Integration with procurement and inventory
The bill of materials feeds purchasing and stock management with reliable requirement figures, so you order what is needed and stock levels stay accurate.
Who we build bill of materials software for
Bill of materials management plays a role in almost every manufacturing environment, but the requirements differ by type of production. For each of these we build software that suits the complexity of the product.
Machinery and equipment manufacturing
Companies with complex, multi-level products and many variants, who need tight revision control and reliable production planning.
Suppliers and metalworking
Suppliers who manufacture to drawing and need the right materials and operations per order, with integration to warehouse management.
Electronics and assembly
Electronics manufacturers with component lists and traceability. See also our software for the electronics industry.
Configurable products
Companies that assemble products from modules, where a chosen configuration automatically produces the correct bill of materials and material requirements.

We build with a modern, maintainable web stack and connect to the systems relevant to BOM management: your production planning, a MES system, procurement and inventory, and CAD or PDM where needed. This way the product structure remains the reliable source for the entire chain.
Why choose Appfront for your bill of materials software?
Appfront builds custom software and starts with a thorough analysis of your products, your revision logic and the way you cost and purchase. A bill of materials is not a side issue but the foundation on which production, purchasing and costing rely.
We build transparently and document clearly, so your engineering and production planning teams understand and manage the software. No black box, just clear agreements on structure, revisions and integrations.

Security and privacy
Bills of materials contain valuable business knowledge about your products and costs. That is why we record the lawful basis for each data flow, apply data minimisation and set up authorisation based on role and necessity. Every access and change is logged, so it remains traceable who viewed or modified what.
We build in line with OWASP security standards and the GDPR, with encryption in transit and at rest, backups and a tested recovery process. We document data flows and authorisations so that you can demonstrably stay in control and keep your record of processing activities complete.
Discuss your situation without obligation via our contact form. We are happy to help you think through architecture, integrations and management.

Frequently asked questions about bill of materials software
Answers to the questions we are asked most often about custom bill of materials software.
Bill of materials software manages the BOM: which components, subassemblies and materials a product consists of and in what quantities, often across multiple levels. It is the foundation on which production, purchasing and costing rely. Custom software lets you set this up in line with your own product structure and revision logic.
Bill of materials software describes what a product is: its structure, components and materials. Production planning software determines when and with what capacity something is made. They complement each other: the BOM provides the material requirements, and the planning turns these into work orders. We build them so they connect seamlessly.
Yes. We build nested bills of materials with unlimited levels, where subassemblies can be reused across several end products. Quantities calculate automatically, so a change at one level flows correctly through to every product in which that subassembly appears.
We record every change to a bill of materials as a revision with number, date and reason, so the history stays complete. You can see which version is valid and which has gone into production, and if necessary revert to an earlier state. This prevents production from being run on an outdated bill of materials.
Yes. The bill of materials feeds into material requirements, which we integrate with purchasing and inventory management. This way, only what is needed gets ordered and stock levels stay accurate, without separate lists drifting out of sync.
Yes. We build imports from CAD or PDM systems, as well as from Excel or CSV, so you don't have to re-enter existing bills of materials by hand. Where you want it, we set up an ongoing integration so engineering and BOM management stay in step.
We build custom software. Product structures, revision logic and costing differ greatly between manufacturers. Custom software fits your actual situation and can grow with you. After an intake conversation, we decide together which functionality matters most and in what order we develop it.
