Is a Purchase Order the Same as an Invoice?
Uncover the fundamental differences and collaborative roles of purchase orders and invoices in managing business transactions.
Businesses use various documents for transactions. Two common documents, the purchase order and the invoice, are key to these processes. Both track goods and services, but serve distinct functions in the procurement and payment cycle. Understanding their roles and interaction is important for business operations.
What is a Purchase Order?
A purchase order (PO) is a commercial document issued by a buyer to a seller, indicating types, quantities, and agreed prices for products or services. Its purpose is to formalize a buyer’s intent to purchase before goods or services are provided. The buyer creates and sends the purchase order to the seller after negotiating terms.
A purchase order includes a unique PO number, date of issue, and details for both buyer and seller. It specifies item descriptions, quantities, and agreed-upon unit and total prices. A PO outlines delivery dates, shipping instructions, and payment terms, such as “Net 30,” meaning payment is due 30 days after the invoice date. Once the seller accepts the purchase order, it becomes a legally binding contract between the buyer and the seller.
What is an Invoice?
An invoice is a commercial document issued by a seller to a buyer, requesting payment for goods or services that have already been provided. Its purpose is to demand payment and itemize the financial transaction. The seller creates and sends the invoice to the buyer after the goods have been shipped or the services have been rendered.
An invoice includes a unique invoice number, date of issue, and due date for payment. It lists seller’s and buyer’s contact information, an itemized breakdown of goods or services, quantities, unit prices, and the total amount due. Payment terms, such as “Net 30” or “due upon receipt,” are stated on the invoice.
How Purchase Orders and Invoices Differ
Purchase orders and invoices, while both part of the transaction process, differ in their purpose, creator, timing, and legal implications. A purchase order is an authorization to buy, originating from the buyer, and is issued before the transaction occurs. It serves as the buyer’s commitment to purchase specific items at agreed prices. In contrast, an invoice is a request for payment, created by the seller, and is issued after the goods or services have been delivered.
The direction of flow distinguishes these documents. A purchase order flows from the buyer to the seller, initiating the procurement process. An invoice, however, flows from the seller to the buyer, signaling the completion of the sale and the obligation to pay. Legally, a purchase order represents a commitment to buy, establishing the terms of the sale. An invoice, on the other hand, is a demand for payment based on the fulfillment of those terms, documenting the amount owed for services rendered or products supplied.
How Purchase Orders and Invoices Work Together
Purchase orders and invoices are interconnected in a business transaction workflow. The process begins with the buyer issuing a purchase order to the seller, outlining the intended acquisition. After the seller accepts this purchase order and fulfills the request, they then generate an invoice.
This invoice references the original purchase order number for cross-referencing. Businesses use both documents in a reconciliation process, commonly known as a “three-way match.” This involves comparing the purchase order, the invoice, and the receiving report (which confirms goods were received) to ensure that the order was correctly placed, the goods were received, and the invoice accurately reflects the agreed-upon terms before payment is released.
