🏗️ Step-by-Step: Example of `Madrid Sofa` Setup:

✅ 1. Define Raw Materials

These are the lowest-level components (foam, fabric, zippers, etc.)

Go to Products/Services > New Product:

Create entries like:
  * HR Foam 40D – Seat
  * Fabric – Outdoor Grade A
  * Polyester Thread
  * Zipper YKK 60cm
  * Velcro Tape
  * Plastic Bag (Rain Cover)
  * Loss (%) – you may represent loss in BOM quantities (see below).

For each:
  * Type: Product
  * Nature: Purchasable
  * Stock management: Enable
  * Unit: e.g., meters, pcs, kg, etc.
 
✅ 2. Define Sub-Assemblies (Components)

These are assembled from raw materials:
  * Mattress Cushion
  * Back Cushion
  * Pillow
  * Rain Cover

Create each as a Product, nature = Manufacturable, and assign a BOM (see Step 5).
 
✅ 3. Define the Finished Good

Create:
•	Madrid Sofa
  * Type: Product
  * Nature: Manufacturable
  * Stock: Managed
  * Selling: Enabled (if you sell it directly)
  * Unit: pcs
 
✅ 4. Create BOMs

Go to MRP > Bill of Materials

Click New bill of materials for each manufacturable item.

📌 A. BOM for "Mattress Cushion"

  * Component	Quantity	Note
  * HR Foam 40D – Seat	2 pcs	
  * Fabric – Outdoor	3 m	
  * Polyester Thread	50 m	
  * Zipper YKK 60cm	2 pcs	
  * Loss (built-in)	Add 5–10% to quantities if needed manually	

📌 B. BOM for "Back Cushion"

Same style – just list relevant raw materials.

📌 C. BOM for "Rain Cover"

  * Component	Quantity
  * Plastic Bag	1 pcs
  * Velcro Tape	2 m
  * Thread	10 m

📌 D. BOM for "Madrid Sofa"

  * Sub-assembly	Quantity
  * Mattress Cushion	1
  * Back Cushion	1
  * Pillow	2
  * Rain Cover	1
  * 
✅ Tip: If you need multi-level BOMs, Cushion can handle it by creating a BOM for each component, and using them inside the top-level BOM.
 
✅ 5. (Optional) Add Suppliers and Purchase Prices

For each raw material:
  * Go to Product > Suppliers
  * Add supplier reference, price, and conditions.
 
✅ 6. (Optional) Create Manufacturing Order

Once BOMs are in place, you can:
  * Go to Manufacturing > New Order
  * Select Madrid Sofa
  * It will calculate all subcomponents recursively
  * You can execute the production and deduct materials from stock
 
✅ Summary

You’ve now modeled:
  * Raw Materials → defined and stock-managed
  * Components → each has its own BOM
  * Finished Good → final BOM uses components
  * Optional: Suppliers, stock, and purchasing details
