Purchase Order vs. Invoice: What's the Difference?
A purchase order is a buyer's official request to a seller for goods or services, while an invoice is the seller's bill for those goods or services after they've been delivered or performed.
A purchase order is a document issued by a buyer to a seller, indicating the types, quantities, and agreed prices for products or services. An invoice, on the other hand, is a document issued by the seller to the buyer, listing the goods or services provided and stating the amount due.
The main objective of a purchase order is to provide clear communication and specifics to the seller about what the buyer wants. The invoice serves as a demand for payment, confirming the sale and indicating the amount the buyer owes.
From a transaction flow perspective, the purchase order typically comes before the delivery of goods or services, while the invoice is presented after the delivery. Essentially, a purchase order sets the expectations for the transaction, and the invoice confirms that those expectations were met.
In terms of legal implications, a purchase order is a formal offer to buy and can become a binding contract once accepted by the seller. An invoice, in contrast, is a record of the sale and is used as a basis for payment.
While both documents contain details about items, quantity, and price, a purchase order might also include delivery dates, payment terms, and other conditions. An invoice will typically have payment terms, due dates, and information related to discounts or late fees.
