MAKE YOUR FREE Purchase order

A purchase order, also known as a work order, confirms an order of goods or services by a purchasing company (the client) from the provider (supplier). It sets out types and quantities of goods purchased, specifies any services requested, and includes the details of agreed costs. Purchase orders are used by many businesses as part of their standard purchasing processes to clarify terms of transactions, prior to services being carried out or goods being delivered by the supplier.

Whether you're a purchaser or seller, use this purchase order template when buying, ordering or providing goods and services. In addition to the existing terms and conditions, this purchase order template will act as a formal offer for the supply of goods and/or services in return for payment.

A purchase order forms part of the overall contract, explicitly stating what has been requested by the client or purchaser and setting out additional terms. It helps the buyer by ensuring that all costs are specified in advance, and it also serves as proof to the seller of what has been ordered. As such, it can be used by both businesses during a transaction.

As well as serving as proof of intentions, purchase orders can also improve the streamlining of purchasing processes and help ensure that accurate records are kept for accounting and auditing purposes.

A purchase order should include the following:

• The word 'Purchase Order' should be clearly displayed;
• A unique purchase order (PO) identification number;
• The date the purchase order was created;
• Agreed dates for delivery of goods and/or services;
• The company name (individual name if sole trader) of both vendor and purchaser and contact details;
• A description of the goods or services ordered and individual costs/fees;
• The total cost, any agreed delivery fees and VAT if applicable; and
• Any agreed payment terms.

A purchase order requests the provision of specific goods or services; the invoice requests payment for the supply of these goods or services.

Purchase orders should always precede invoices. A purchase order may be used as the basis of an invoice, and invoices should always reflect the details contained in a purchase order (in particular the agreed fees/amounts). Many purchasers require the relevant purchase order number to be included in any invoice in order to streamline their processing and ensure that everything tallies up.

A purchase order can include a note of any payment period, if agreed, or a preferred payment period if one was not discussed (although this may not be binding). The standard payment period is within 30 calendar days of receipt of invoice, beyond which the payment is considered late (unless otherwise agreed) and a statutory demand can be made.

If you only deal with a handful of contractors and prefer to keep things informal, you might choose to omit purchase orders from your transactions. However, some contractors will demand a purchase order before starting work. Also, having a formal contracting system in place, which includes purchase orders, can help to prove the status of contractors - so they are not classified as employees for purposes of IR35.
