Frequently Asked Questions

What is a purchase order?

A purchase order (PO) is a commercial document issued by a buyer to a seller, indicating the type, quantity, and agreed price for products or services. It becomes a legally binding contract once the seller accepts it.

What is the difference between a purchase order and an invoice?

A purchase order is created by the buyer before goods or services are delivered — it authorizes the purchase. An invoice is created by the seller after delivery — it requests payment. The PO comes first, the invoice follows.

Is a purchase order legally binding?

A purchase order becomes a legally binding contract once the seller accepts it. It commits the buyer to pay for the specified goods or services at the agreed price and terms.

What should a purchase order include?

A standard purchase order includes: PO number, buyer and vendor details, item descriptions with quantities and unit prices, delivery date, payment terms, shipping instructions, and authorized signatures.

Can I convert a purchase order to an invoice?

Yes. Once goods are delivered and accepted, the vendor can reference the PO number to create a matching invoice. Eonebill makes this seamless with PO-to-invoice conversion.
