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.
