A purchase order (PO) is a legal document sent by a buyer to their supplier. It demonstrates their commitment to pay for specific products and/or services from a seller, and establishes terms for payment.
A PO communicates the buyer’s needs to the seller, and establishes their expectations for the transaction. Whether you’re making a capital investment or simply purchasing new items to add to your inventory, the transaction starts with a purchase order.
Purchase orders can be helpful as they simplify the buying process. The process of buying goods with a purchase order is typically as follows:
- The buyer identifies a need for a product or service
- A PO is issued to the seller, either electronically or by post using purchase order templates
- The supplier receives the PO and confirms they are able to fulfil the order
- If they can fill the order, the supplier gets to work allocating stock or personnel
- If the order cannot be fulfilled, buyer is notified and the order is cancelled
- Goods are shipped or services provided. A PO number is assigned so that both parties can identify the specific order
- The seller then sends an invoice for the order, matching it to the PO number
- The buyer pays the invoice in accordance with the terms established in the PO
Purchase order example
Now you know the definition of a purchase order – but what does an example look like?
Although a PO is a legal document, there is no specific format a purchase order form should take. Whether you use our templates or create your own form from scratch, your PO should contain the following information:
- A unique PO number for the transaction
- Billing and shipping addresses for the buyer
- The supplier’s address, phone number and email address
- Order and delivery dates
- Names of personnel/departments that requested and approved the order
- An itemised list of goods to be purchased (including item codes/SKU numbers and prices)
- Payment terms
- Any applicable discounts
- The total value of the order (including VAT where applicable)
Advantages and disadvantages of using a purchase order
Purchase orders can simplify the ordering process, improving visibility and accuracy when managing your company’s finances. Because funds need to be available before a PO is issued, using them encourages better budgeting to manage operating cash flow.
Because they clearly set out the buyer’s expectations, they help to insulate against unpleasant surprises, and can facilitate fast and frictionless delivery of goods.
However, they can add a layer of administration that may bottleneck efficiency for smaller companies. Using a business credit card may help smaller companies to achieve the same ends more efficiently.
