A purchase order (PO) flows from the buyer to the supplier: it is the buyer’s official offer to buy specific goods or services at agreed quantities and prices, issued before anything is delivered, and it becomes a binding contract once the supplier accepts it. An invoice flows the other way — from the supplier to the buyer — after the goods or services have been delivered, to request payment, and it should reference the original PO number. So the typical workflow is: buyer issues a PO, supplier accepts and fulfils it, then supplier sends an invoice, and finally a receipt documents the money received. Use AnyTool’s Purchase Order Generator to issue the order, and the Invoice Generator when you are the seller requesting payment.

AnyTool’s Purchase Order Generator is completely free with no account, no watermark and no sign-up wall. The PO is assembled and the PDF is built entirely on your device using a local engine, so your buyer details, the vendor’s details, the ship-to and bill-to addresses, your line items and even your uploaded logo never leave the browser. An optional “Save draft” keeps a copy only in this browser’s local storage, which you control and can clear with Reset.

A professional purchase order usually carries a unique PO number, the buyer’s name, logo and contact details, the vendor / supplier’s details, an issue date and a required-by / delivery date, a ship-to address (where the goods are delivered) and a bill-to address (where the invoice goes), the shipping method and payment terms, an itemised list of goods or services with quantity and unit price, the subtotal, applicable tax, any shipping charge, the order total, terms and conditions, optional notes, and an authorised-signature line. AnyTool’s Purchase Order Generator provides all of these fields. It is a document generator, not procurement or tax software — confirm the rules for your country.

On its own a purchase order is the buyer’s offer to buy and is not yet a binding contract. It becomes legally binding once the supplier accepts it (by confirming, acknowledging or beginning to fulfil the order), at which point both parties are committed to the items, quantities, prices and terms on the PO. Because of this, you should verify the quantities, unit prices, ship-to / bill-to addresses, required-by date and terms before sending it. A PO is still not a demand for payment — payment is only due once the supplier delivers and issues an invoice referencing the PO number. This tool produces the document; it is not legal, procurement or tax advice.
