A purchase order (PO) is a formal document from a buyer to a supplier that commits to purchasing specific goods or services at agreed terms. It becomes a legally binding contract when the supplier accepts it. Use POs when you need a paper trail for approval processes, when ordering from new vendors, or when your accounting requires matching POs to invoices before payment.

A PO is created by the buyer and sent to the supplier before goods are delivered — it's a commitment to buy. An invoice is created by the supplier and sent to the buyer after delivery — it's a request for payment. In a typical purchase cycle: you send a PO → supplier delivers and sends an invoice → you match the invoice to your PO → you pay.

Net 30 means the invoice is due 30 days after the invoice date. Net 15 = 15 days, Net 60 = 60 days. "2/10 Net 30" means you get a 2% discount if you pay within 10 days, otherwise full amount is due in 30 days. "Due on Receipt" means payment is expected immediately upon delivery.

Tip: open More settings in the print dialog and turn off "Headers and footers" — otherwise the date and foxmargin.com URL will appear at the top/bottom of your saved PO.
