What Is a Purchase Order and Types of Purchase Orders?
A purchase order (PO) is a formal document sent by a buyer to a seller to confirm a purchase. It outlines what's being ordered, in what quantity, and at what price.
There are several types of purchase orders:
- Standard POs – Used for routine, one-off purchases.
- Blanket POs – Used for recurring orders over a longer period.
- Contract POs – Created for legal agreement purposes without item details yet.
- Planned POs – Include estimated dates and quantities for future deliveries.
Creating a professional PDF PO helps clarify expectations and protects both parties in case of disputes.
Information You Should Include in a Purchase Order
Before you begin, make sure your purchase order includes:
- Purchase order number
- Buyer and seller details
- Order date
- Item descriptions and quantities
- Unit prices and total amount
- Shipping method and terms
- Billing and delivery addresses
- Signature or approval area
How to Create a Purchase Order
There are a few easy ways to create a purchase order, depending on what tools you're using.
If you're starting from scratch, you can:
- Use Microsoft Word to build a basic PO with tables for items and totals.
- Use Excel to calculate prices and taxes automatically with built-in formulas.
- Use Google Docs or Sheets if you need to collaborate with others.
Make sure to include all key sections we mentioned above. If you want to save time, you can also start with a purchase order template; many free ones are available online.
Just customize the fields to match your needs, then you're ready to convert it to PDF for sharing or printing.
