UK Purchase Order Template: What to Include and How to Use

A UK purchase order template is a reusable form a buyer fills in to request goods or services from a supplier. Use the blank template below to record what you are ordering, the agreed prices, delivery details and the people who need to approve it; adapt the fields to your organisation and the type of purchase.

What a purchase order does

A purchase order, often shortened to PO, is a document issued by a buyer to a supplier. It identifies the proposed purchase and gives both sides a reference for discussing, supplying and recording it. A PO commonly covers a single order, although an organisation may use other arrangements for recurring purchases.

There is no single UK government-issued layout that every business must use. The appropriate form depends on what is being bought and how the buyer and supplier work together. A small business might use a numbered spreadsheet or printable form; a larger organisation may have an approval process and a standard electronic record. In either case, the information should be clear enough for the supplier to understand the request and for the buyer to check the delivery and invoice later.

A PO is not just a note of what someone hopes to buy. Depending on the wording, the parties’ communications and the circumstances, it may form part of a contract or contribute to one. Avoid treating an issued PO as harmless paperwork: make sure the person issuing it has authority and that its terms do not conflict with agreed quotations, contracts or other purchase terms.

Copy or print this generic form and complete the relevant fields. Leave an item row unused if it is not needed, and attach a specification or quotation when the details will not fit. The sample is fictional and shows how a completed order might look.

Fields to include and why they matter

At a minimum, identify the buyer, supplier, order date, items or services and the quantities. A unique PO number makes it easier to match the order to supplier correspondence, delivery records and an invoice. Use a consistent numbering method, such as a year prefix followed by a sequence, and check that numbers are not reused.

Describe the purchase precisely. “Computer equipment” is less useful than a description that states the relevant model, specification, size or agreed service deliverable. Where a quotation or contract contains detailed specifications, name its reference and attach or retain the version agreed by both parties. For services, state the scope, dates or milestones and any expected outputs rather than relying on a vague label.

Include the delivery address, requested date, contact person and any practical instructions the supplier needs. Record the agreed price and unit of measure, such as each, hour or box. If relevant, show a subtotal, VAT amount or rate, and total as separate figures. The VAT entries are useful for communicating the agreed price, but the PO is not a substitute for a VAT invoice. Invoice and VAT record requirements depend on the transaction and the parties’ circumstances.

• State payment terms only when they have been agreed, and make the wording consistent with the relevant contract or supplier agreement.
• Identify who authorised the order, and add a cost centre, project code or internal reference if your organisation uses one.
• For delivery in stages, say what is due at each stage and how quantities or charges will be recorded.

How the purchase order process works

A useful process starts before the form is sent. The requester defines the need, checks the specification and obtains any quotation or internal approval required by the organisation. The person preparing the PO then checks that the supplier details, price, delivery arrangements and terms match what was agreed. For a significant or unusual purchase, it is sensible to resolve discrepancies before issuing the document.

1. Complete the PO with a unique reference and the agreed order details.
2. Obtain the required approval before sending it to the supplier.
3. Send it to the supplier’s appropriate contact and retain a copy with any quotation or supporting specification.
4. Ask the supplier to confirm receipt or acceptance where that is part of the process, especially if dates, stock or scope need confirmation.
5. When goods or services arrive, compare them with the PO and record any shortfall, damage, change or partial delivery.
6. When an invoice arrives, compare it with the PO and the delivery or completion record before processing it under your normal procedures.

The PO can reduce misunderstandings, but it cannot guarantee that the supplier will deliver as expected. A clear record helps the buyer identify what was ordered and gives both parties a reference if the delivered quantity, price or specification differs. If a change is agreed after issue, record it in a revised PO or a clear written variation, rather than silently changing the original file.

Choosing a format for your business

For occasional, straightforward purchases, a printable document or spreadsheet can be enough. It is easy to tailor and share, but users need to control versions, protect the file from accidental edits and keep a reliable copy of each issued order. A template should make key fields visible without forcing users to fill irrelevant boxes.

An electronic form or purchasing system may suit an organisation with many requesters, several approval levels or regular repeat orders. It can help standardise numbering and make records easier to find, but only if access, approval rules and retention practices are set up sensibly. A digital process is not automatically more accurate: check that staff can correct errors transparently and that the final issued version is preserved.

Choose a format by considering how often you order, how many people need to approve purchases, whether orders need multiple delivery lines, and how you will match invoices and receipts. Keep the template proportionate. A one-off purchase of stationery does not need the same detailed fields as commissioned work with milestones, technical requirements or several delivery locations.

Purchase orders, quotations and invoices

These documents have different roles. A quotation is normally a supplier’s statement of proposed prices and terms, subject to its wording and any agreed conditions. A purchase order is normally issued by the buyer to place or document an order. An invoice is a supplier’s request for payment for goods or services supplied, or as otherwise agreed. The exact effect of a document depends on its content and the surrounding agreement, not just its title.

For example, a supplier may quote for 20 chairs at a stated price, and the buyer may issue a PO referring to that quotation. The PO should identify the same quantity, specification and price. If it instead says 25 chairs or adds different delivery terms, the documents no longer describe the same deal. The parties should clarify which terms apply before treating the order as settled.

A PO is also not proof that goods were received, work was completed or payment was made. Keep appropriate delivery or completion evidence and the invoice alongside it. For VAT purposes, do not assume that a purchase order serves as the supplier’s VAT invoice; check the applicable requirements for the transaction and keep the relevant records.

Common mistakes and practical checks

Many problems come from small inconsistencies. A wrong delivery address can send an order to the wrong site; a missing unit can turn a price per box into an apparent price per item; and a broad description can make it difficult to decide whether a delivery meets the agreed specification. Review the document as if you were the supplier receiving it without the background conversation.

• Check names, addresses, contact details and the supplier’s reference against the quotation or agreement.
• Confirm arithmetic, quantities, units, delivery charges and any stated VAT figures before approval.
• Do not leave a material field ambiguous. Write “delivery by 30 June” rather than “soon” if a date has been agreed.
• Do not add new conditions casually if they conflict with terms already agreed or accepted.
• Mark a cancelled or superseded PO clearly, and tell the supplier so an old version is not acted on.
• Keep a record of any agreed amendment, including who approved it and when it was communicated.

One common misconception is that a PO can always be withdrawn simply because it has not yet been paid. That is not a safe assumption: the effect of an order, cancellation wording and any supplier acceptance can depend on the facts and applicable terms. If a particular purchase raises a legal or tax question, ask a qualified professional.

Approvals, numbering and record keeping

Set approval steps according to your organisation’s own policies and the nature of the purchase. A sole trader may be the requester and approver, while a larger organisation may separate requesting, approving and paying roles. Whatever the size, make it clear who can commit the buyer to an order and how an approval is recorded. A signature is one option; a dated approval in a controlled electronic process may also create a useful audit trail.

Store the issued PO with the related quotation, contract or specification, supplier confirmation, delivery evidence, invoice and any amendment. Use a predictable filing method, such as the PO number, so someone reviewing the transaction later can locate the complete record. Restrict access to records where appropriate, and follow your organisation’s retention and data-handling policies.

Review the template when your buying process changes. For example, if you begin ordering services in stages, add fields for milestones and completion dates. If recurring orders are covered by a separate agreement, make the relationship between that agreement and each PO clear. A template should support the real process rather than create the appearance of approval without the necessary checks.

Frequently Asked Questions

Is a purchase order legally required in the UK?
No single PO format is generally required for every UK purchase. Businesses often use POs as an operational control and shared record. Whether a particular order creates obligations depends on the documents, communications and circumstances, so do not rely on the form’s title alone.

Can I use this purchase order template as a sole trader?
Yes. A sole trader can adapt a simple template for business purchases, using clear supplier, item, price and delivery details. Keep the issued copy and related records, and follow any terms agreed with the supplier. Add approval fields only if they are useful for your process.

Does a purchase order need to show VAT?
There is no universal PO layout that makes a VAT field compulsory for every buyer and purchase. If VAT is relevant, showing the agreed amount or rate separately can make the order easier to check. A PO is not a substitute for a VAT invoice, and transaction-specific questions should be checked with a qualified professional.

Should I send a purchase order before or after receiving an invoice?
A PO is commonly sent when placing an order, before supply and invoicing, so the supplier can see what the buyer is requesting. Businesses may have different arrangements, but issuing an order retrospectively can make approval and matching less clear. Follow the agreed purchasing process.

Can I change or cancel a purchase order after sending it?
Contact the supplier promptly and document any proposed change or cancellation. Do not assume the original order can be withdrawn unilaterally; the outcome may depend on the terms and what the parties have agreed or done. For a disputed or significant order, seek qualified advice.

A well-used UK purchase order template is specific, consistent with the agreement, approved by the right person and kept with the records that show what happened next. Start with the blank form above, remove fields you do not need, and add detail where the goods, services or delivery arrangements require it.
