How to Create a Purchase Order for Your Vendors (Step by Step)

To create a purchase order, list your business details, the vendor's details, a unique PO number, each item with its quantity and unit price, the total, and a delivery date, then send it to the vendor before they start fulfilling the order. Leaving out any one of those six pieces usually means an email back and forth before the vendor will process it. Ask the vendor to put your PO number on their invoice, so the two documents can be checked against each other in a glance rather than a line-by-line comparison.

What Goes on a Purchase Order

A usable purchase order needs six things: your business details, the vendor's details, a unique PO number, each item with quantity and unit price, the total, and a delivery date. Anything less and the vendor is likely to email back asking for the missing piece before they'll process it.

Building One Step by Step

1. Add your company details: name, address, and a contact for order questions.
2. Add the vendor's details: the supplier you're ordering from.
3. List each item: description, quantity, and the agreed unit price.
4. Set a delivery date: the date you need the order fulfilled by.
5. Send it before work starts: a PO issued after delivery has already happened defeats the purpose.

Matching the PO to the Eventual Invoice

When the vendor's invoice arrives, check it against the original PO: same items, same quantities, same price. Ask vendors upfront to put your PO number on their invoice: it turns a manual line-by-line comparison into a quick side-by-side check.

Keeping the Process Fast

The main reason small businesses skip purchase orders is that writing one from scratch each time feels like unnecessary overhead for a routine order. A free purchase order generator that remembers your company details and auto-numbers each PO removes that friction, so issuing one takes about as long as sending a quick email.
