Purchase Order Best Practices for Small Businesses

A purchase order (PO) is more than paperwork — it is a practical control tool. When your business grows beyond occasional supply runs, POs help you document what was ordered, at what price, and when it should arrive.

When Should You Use a Purchase Order?

Use a PO whenever you are buying goods or services from an external vendor and want a written record before payment. Common examples include:

• Ordering inventory or raw materials from a supplier
• Requesting equipment or office supplies
• Hiring a subcontractor for a defined scope of work

What Belongs on a Purchase Order?

A useful PO typically includes:

• Vendor details — company name, contact person, and address
• Buyer details — your business name and billing address
• PO number — a unique reference for tracking
• Line items — description, quantity, unit price, and total
• Delivery date and shipping instructions
• Payment terms — Net 30, due on receipt, etc.

Why POs Matter for Cash Flow

Without a PO, it is easy to lose track of open orders. You might receive an invoice for items you did not expect, or pay twice for the same shipment. POs create a checkpoint: you approve the order first, then match the vendor invoice against it.

Common Mistakes to Avoid

• Skipping PO numbers and relying on email threads alone
• Not specifying delivery dates, which leads to inventory gaps
• Failing to share POs with your bookkeeper or accountant
• Treating verbal agreements as sufficient for large purchases
