What is a purchase order for?

It documents exactly what a buyer is ordering from a vendor — items, quantities, prices, and delivery terms. Once accepted by the vendor, it serves as a binding agreement and a reference for checking the invoice.

How is a PO different from an invoice?

The buyer issues the purchase order before the sale; the vendor issues the invoice after fulfilling it. Matching invoice to PO is how businesses catch billing errors before paying.

Can I duplicate a PO for repeat orders?

Yes. Completed purchase orders live in your dashboard, so you can copy a previous one, update the PO number, date, and quantities, and send it in a minute or two.

Why businesses use purchase orders

A purchase order (PO) is a buyer's formal offer to purchase: it tells a vendor exactly what you want, in what quantity, at what price, delivered where and by when. Once the vendor accepts, the PO becomes a binding agreement — which is precisely its value. It replaces "I thought we agreed on fifty units" with a numbered document both sides can point to, and it gives your bookkeeper a clean way to match invoices against what was actually ordered.

The anatomy of a PO

A complete purchase order carries a unique PO number, the issue date, buyer and vendor details, a shipping address, itemized lines with descriptions, quantities, unit prices, and line totals, plus the subtotal, tax, shipping, and grand total. Delivery date, payment terms (Net 30 is common), and any special instructions round it out. The PO number matters more than it looks — it's the thread that ties the order, the delivery, and the invoice together in three-way matching.

Creating yours online

Fill in the FinishMyDocs template in your browser: add vendor details, line items, and terms, then download a polished PDF to email to your supplier. Your issued POs stay in your dashboard, giving even a one-person shop a real audit trail without procurement software. When the vendor's invoice arrives, a thirty-second comparison against the PO catches pricing and quantity errors before you pay them.
