Purchase order vs. invoice: Roles and differences

In an overwhelming domain of business transactions, understanding the differences between purchase orders and invoices are crucial for efficient operations. Both documents play distinct roles within the procurement and payment processes. A purchase order initiates a transaction detailing the buyer's requirements, while an invoice follows, requesting payment for the goods or services provided.

Knowing how a purchase order is different from an invoice can help businesses maintain financial control, avoid discrepancies and ensure smooth transactions. In this blog, we will explore purchase order vs. invoice and clarify how a purchase order differs from an invoice.

What is a purchase order?

A purchase order (PO) is a document made by a buyer to request services or goods from a seller formally. It outlines specific details such as the types of products or services, quantities, agreed-upon prices, delivery dates and payment terms.

The purchase order acts as a contractual agreement between the buyer and the seller initiating the purchasing process. When comparing a purchase order with invoices, it's essential to understand that a purchase order comes first in the sequence, setting the stage for the entire transaction.

Key features of a purchase order

• Authorisation: A PO is typically generated by the buyer's procurement department and is an official authorisation for the seller to provide the goods or services.
• Clarity in transactions: It clearly defines what is being purchased, reducing the chances of disputes or misunderstandings.
• Budget management: Purchase orders help businesses manage budgets and forecast expenses by clearly documenting anticipated costs.
• Legal protection: Since it's a formal agreement, a PO provides legal protection for both parties by outlining the terms of the purchase

What is an invoice?

An invoice, on the other hand, is a document sent by the seller to the buyer after the goods or services have been delivered. It serves as a request for payment, mentioning the amount owed by the buyer. In the context of purchase orders vs. invoices, the invoice follows the PO and completes the transaction by requesting the agreed-upon payment. Invoices typically include the list of goods or services provided, the total amount due, payment terms and the due date.

Key features of an invoice

• Billing document: It acts as a formal request for money from the seller to the buyer, often including details such as tax information and payment methods.
• Record keeping: Invoices are essential for maintaining accurate financial records, which are crucial for audits and tax purposes.
• Payment terms: They specify the payment terms agreed upon, which could include discounts for early payment or penalties for late payment.
• Proof of transaction: An invoice serves as proof that the goods or services were provided, which can be used for financial reconciliation.

How is a purchase order different from an invoice?

While both documents are pivotal in the purchasing and payment processes, their roles and timing are quite different. Here's a breakdown of how a purchase order is different from an invoice:

• Purpose: A purchase order initiates a purchase, whereas an invoice requests payment.
• Timing: POs are issued before the goods or services are delivered, while invoices are sent after delivery.
• Content: A PO includes details about the order, such as quantities and prices, while an invoice details the payment required for delivered goods or services.
• Use in business processes: Purchase orders help with order tracking and budget management invoices are crucial for accounts payable processes.

The workflow: From purchase order to invoice

Understanding the workflow that connects these two documents can help streamline business operations and enhance the understanding of purchase orders vs. invoices:

1. Creating a purchase order: The process begins with the buyer identifying a need for goods or services and creating a purchase order to communicate this need to the supplier.
2. Acceptance by supplier: Once the supplier accepts the purchase order, it becomes a binding contract. The supplier then proceeds to fulfil the order.
3. Delivery of goods or services: The supplier provides the goods or services as per the terms outlined in the purchase order
4. Issuing an invoice: After delivery, the supplier issues an invoice requesting money for the goods or services provided.
5. Payment processing: The buyer reviews the invoice against the initial purchase order and the delivery receipt. If everything matches, the buyer proceeds with the payment as per the agreed terms.

Benefits of using purchase orders and invoices

Both purchase orders and invoices offer numerous benefits to businesses. When comparing purchase orders vs. invoices, it's clear that both play integral roles in ensuring smooth and accountable transactions:

• Enhanced accountability: They provide a clear paper trail, helping to avoid disputes and misunderstandings.
• Improved financial management: These documents help businesses manage cash flow by clearly outlining incoming and outgoing payments.
• Efficiency in operations: Automated systems can use POs and invoices to streamline the procurement and payment processes, reducing manual errors and saving time.
