Advanced BOM Management System | BOM Manager

Stop managing product structures and cost calculations with complex spreadsheets and disconnected systems. Build multi-level Bills of Materials, track raw material costs, calculate product costs automatically, and visualize hierarchical product structures—all in one powerful, fully offline manufacturing management system.

Managing Bills of Materials involves countless complexities—multi-level product structures, raw material costs, assembly dependencies, quantity calculations, and accurate cost roll-ups. Manufacturing engineers, product designers, cost accountants, and production managers need a clear, professional way to build BOM structures, track material costs, and understand product profitability.

The BOM Management System Pro is a comprehensive Single Page Application (SPA) designed for manufacturing engineers, product designers, cost accountants, production managers, and supply chain professionals who need a practical, sophisticated BOM management solution. It helps you define products and raw materials, build multi-level BOM structures with unlimited depth, automatically calculate cost roll-ups, visualize product hierarchies, and generate detailed cost reports—all from a single, intuitive dashboard.

Best of all, it runs 100% offline in your web browser. No SaaS subscriptions, no monthly fees, and no risk of your sensitive product cost data being uploaded to third-party servers. Your BOM structures, material costs, and product configurations stay stored locally in your browser’s IndexedDB, giving you full control over your confidential manufacturing data.

🚀 Key Features for Manufacturing & Engineering Professionals

• 100% Offline & Secure: Store all your BOM data locally in your browser with no cloud dependency or recurring SaaS costs. Uses IndexedDB for persistent, secure storage.
• Product Management: Define and manage finished products with unique identifiers.
• Raw Materials Inventory: Maintain a complete inventory of raw materials with item codes, names, units of measure, and unit costs.
• Multi-Level BOM Builder: Build unlimited-depth Bills of Materials with assemblies and sub-assemblies. Add root assemblies, sub-assemblies, and link raw materials at any level.
• Visual BOM Tree: View your complete product structure as an interactive hierarchical tree diagram. Perfect for presentations and documentation.
• Automatic Cost Roll-Up: System automatically calculates total product costs by traversing the entire BOM tree, multiplying quantities by unit costs.
• Unit Cost Calculation: Each component’s unit cost is calculated recursively—assemblies derive cost from their child components; materials use their defined unit price.
• Cost Summary Dashboard: View the total computed cost for any product with a detailed breakdown by root assembly.
• Product Cost Comparison: See all products’ total costs on a bar chart for quick comparison.
• Advanced Analytics: Analyze cost distribution by BOM level, component type composition, and top expensive materials.
• Interactive Cost Reports: View cost breakdowns with doughnut, pie, or bar charts. Filter by minimum cost threshold.
• Top Materials List: Identify the most expensive materials in your product structure with quantity usage and total cost.
• BOM Level Analysis: Understand how costs are distributed across different BOM hierarchy levels.
• Component Type Composition: Visualize the balance between assemblies and raw materials in your product structure.
• Dashboard Overview: Monitor total products, raw materials, and BOM components at a glance.
• Data Management: Backup your entire BOM database to JSON, restore from previous backups, load sample data (Mountain Bike example), or wipe all data when needed.
• Modern Dark & Light Interface: Work comfortably in a clean, professional manufacturing dashboard with theme switching.
• Responsive Design: Access your BOM management system from any device—desktop, tablet, or mobile.
