🏗️ Bill of Materials (BOM)
A Bill of Materials (BOM) is a list of components and raw materials needed to produce a finished product.
The BOM feature in CushionsERP is built on top of Dolibarr ERP/CRM, offering flexible structure and multi-level BOM support for manufacturing workflows.
🔍 What is a BOM?
A BOM defines:
- The components (materials, semi-finished goods) required
- The quantity of each component
- The finished product being built
It’s used during Manufacturing Orders (MO) to consume raw materials and generate finished stock.
🛠️ A product can have one or more BOMs, which lets you define variants or alternate production methods.
🛒 BOM Components
Each BOM line includes:
- 🆔 Component – A registered product or material
- 🔢 Quantity – Amount needed per unit of finished good
- 📉 Loss (%) – Optional wastage or production loss
- 🏷️ Notes – Optional remarks per line item
📐 Simple vs Nested BOMs
- Simple BOM — A flat list of components used to make a product
- Multi-level BOM — A BOM where some components are themselves finished goods with their own BOM
📦 Example: “Madrid Sofa” may include *Mattress Cushion*, which itself has a BOM of foam + fabric + label.
⚙️ How to Create a BOM
1. Go to Products & Services 2. Select a Finished Product you want to assemble 3. Click on the BOM tab 4. Click Create a New BOM 5. Add components and their quantities 6. Save the BOM
💡 Make sure all components are already registered as products/components in the system.
🔁 BOM in Manufacturing
When you generate a Manufacturing Order, Cushions will:
- Automatically fetch the BOM linked to the product
- Reserve or consume component stock
- Produce finished goods into inventory
You can choose to:
- Manually validate and adjust component usage
- Use Workstation modules (if enabled in Dolibarr) for time tracking and efficiency
📎 Key Considerations
- A product can only have one active default BOM
- Components should have Stock Management enabled
- BOMs can be duplicated or revised for version control
- BOM cost estimation is based on component cost + loss %
🧠 Best Practices
- Always check component availability before production
- Document loss factors clearly in the BOM
- Group BOMs by category or production type
- Review cost breakdown to analyze profitability
📘 Case BOM Study: Madrid Sofa
The “Madrid Sofa” is a finished good composed of multiple subcomponents, each with their own BOM:
* 🛋️ Madrid Sofa (Finished Product)
- 🧩 Mattress Cushions — BOM: Foam + Fabric + Zipper
- 🧩 Back Cushions — BOM: Hollow Fibre + Fabric
- 🧩 Pillows — BOM: Hollow Fibre + Fabric
- 🧩 Raincover — BOM: PVC Sheet + Label
Each of these subcomponents must be defined as products with their own BOMs, so that when manufacturing a Madrid Sofa, all child items and raw materials are automatically accounted for.
🔄 This structure enables multi-level manufacturing with detailed cost and material control.
