When do you need this document
A purchase order is a commercial procurement document sent by a buyer to a seller authorizing the purchase of goods or services at agreed prices and quantities. You need a purchase order whenever your business commits to acquiring supplies, raw materials, software licenses, or contracting services from an outside vendor. Once accepted by the vendor, the purchase order establishes a binding contract between buyer and seller.
It is vital to distinguish between a purchase order and a tax invoice. A purchase order is initiated by the buyer to order items and specify commercial delivery terms. A tax invoice is issued subsequently by the seller under Section 31 of the CGST Act to demand payment after fulfilling the order. A purchase order is an authorization to supply, whereas an invoice is an accounting demand for payment.
What the document must contain
To prevent commercial misunderstandings and procurement errors, a purchase order must clearly document key transaction terms:
- Purchase order serial number and calendar date of issue
- Buyer legal business name, registered address, and GSTIN
- Vendor legal trading name, facility address, and contact representative
- Billing address and distinct physical shipping destination address if different
- Detailed item descriptions, specifications, part codes, and HSN codes
- Ordered quantities, agreed unit rates, and total contracted financial value
- Expected delivery date and transportation terms such as freight on board
- Commercial payment terms specifying advance deposits or credit periods such as net 30 days

Common mistakes
Avoid these common operational pitfalls in procurement documentation:
- Ambiguous item descriptions: Ordering items without specific model numbers, grades, or specifications leads to vendor fulfillment errors.
- Missing shipping destination details: If your warehouse location differs from your corporate head office, failing to state a separate shipping address creates freight delays.
- Omitting payment credit terms: Not stating whether payment is due on delivery or on a net 30 day credit window causes commercial friction upon invoice receipt.
- Unsigned purchase orders: An unapproved purchase order without an authorized signature line may not be recognized as a valid procurement commitment.
