# Material Procurement Procedure
The procurement of materials in a manufacturing organisation follows a structured sequence of steps. Understanding this flow is essential because each document generated during the process has a specific costing and control purpose.
## Sequence of Steps
### 1. Bill of Materials (BOM)
The Engineering Department prepares a complete specification of:
- Shape of the material
- Size of the material
- Quality required
- Quantity required
This acts as the master list of materials needed for a job/product.
### 2. Material Requisition Note (MRN — requisition)
Whenever the Production Department needs materials, it sends a list of required materials to the Stores Department (Godown).
- Issued by: Production Dept
- Sent to: Stores Dept
- Purpose: Internal indent of material
### 3. Purchase Requisition
If materials are about to finish in stores, the Stores Manager informs the Purchase Department to buy the material.
- Issued by: Stores Dept
- Sent to: Purchase Dept
- Purpose: Trigger for outside procurement
### 4. Inviting Tenders / Quotations
The Purchase Department invites quotations from different suppliers of the material.
### 5. Selection of the Best Tender
All tenders are analysed on the basis of:
- Quality
- Price
- Other terms (delivery, credit, etc.)
The best tender is selected and finalised.
### 6. Purchase Order Placed
After the tender is finalised, the Purchase Department places the order for the material with the selected supplier.
### 7. Receipt & Inspection of Material
Once material arrives, proper inspection is done to check whether the materials match the description, quality and quantity ordered.
### 8. Goods Received Note (GRN)
After inspection, defective units are returned and for the good quantity, a GRN is issued.
### 9. Material Return Note (MRN — return)
If defects are discovered after receipt and entry into stores, the defective goods are returned using a Material Return Note.
- Note the contrast: GRN is at inspection; Material Return Note is post-storage discovery of defect.
### 10. Payment
After all adjustments (returns, rejections, discounts), payment is made to the supplier.
