A purchase order is a buyer-issued document that tells a vendor what you want to buy, at what price, and under which delivery and payment terms. It is distinct from an invoice, which the seller issues to request payment after goods or services are supplied. It is also distinct from a receipt, which proves payment received, and from a quote or estimate, which usually comes before approval.
A simple purchase order template gives you a repeatable way to record the buyer, seller, item description, quantity, unit price, expected delivery date, shipping address, billing address, payment terms, and approver. Small teams use it to avoid loose email approvals, missing quantities, and vendor disputes over what was ordered. The finished document should be clear enough for the vendor to fulfill without asking for the same details again.
Start with a purchase order number, issue date, buyer name, buyer contact, vendor name, and vendor contact. Add each item or service on its own line with a description, quantity, unit price, and extended amount. Include delivery terms, shipping address, billing address, requested delivery date, payment terms, and any internal project, department, or cost code that your approval process requires.
Tax treatment belongs in the purchase order only when it helps the buyer and seller agree on the expected amount. The United States does not use a national VAT or GST invoice regime, and there is no single national sales tax rate. State and local sales and use tax rules depend on the jurisdiction, nexus, product or service taxability, and place of sale, so a purchase order should avoid pretending that one flat tax rule applies everywhere.
A simple template should remove friction, not remove the fields that prevent mistakes. Keep the layout to one header, one vendor block, one buyer block, one line-item table, one totals area, and one approval area. Optional fields belong only where they support the purchase, such as a project code for client work, a delivery contact for shipped goods, or a contract reference for recurring vendor orders.
The biggest mistake is treating a purchase order like a finished invoice. A purchase order authorizes or requests a purchase; it does not prove that the seller delivered the work or that payment is due. For federal procurement, a later proper invoice has its own FAR-defined fields, including contractor details, invoice date and number, contract or order references, line items, terms, payee details, and required TIN or EFT data when agency procedures require them.
A free template is enough for a one-time vendor order, a small equipment purchase, or a simple service request where one person approves the spend. It gives you a downloadable record and a clear document to send before the vendor starts work. It also works when the buyer already has a separate accounting system that controls approvals, payments, and vendor records.
A managed workflow is better when purchase orders connect to client projects, billable work, internal cost rates, or recurring vendor spend. Everhour separates cost and billable rates, supports per-person defaults and per-project overrides, and preserves dated rate history, so teams can compare internal cost against client-facing billing before work reaches the invoice stage.

A purchase order is not the same as an invoice. The buyer sends a purchase order to request or authorize goods or services. The seller sends an invoice to request payment after providing those goods or services. A receipt comes after payment and proves that payment was received.
A usable purchase order includes a PO number, issue date, buyer and vendor details, item or service descriptions, quantities, unit prices, totals, delivery details, payment terms, and approval information. A project code, department, or contract reference also helps when the buyer needs internal tracking.
A purchase order can include an estimated tax line when the buyer and seller need an expected total, but United States sales and use tax is not a national VAT or GST system. State and local rules control whether tax applies, which rate applies, and whether a product or service is taxable.
A PDF purchase order is acceptable for ordinary private-sector buying when both parties accept that process. United States federal tax recordkeeping does not prescribe one private-sector invoice or purchase order form. Businesses need records that clearly show income, expenses, and transaction support.
Missing line-item detail causes the most avoidable delays. A vendor needs the exact item or service description, quantity, unit price, delivery address, requested date, and buyer contact. A vague line such as "consulting services" or "office supplies" forces the vendor to confirm details before fulfilling the order.
Everhour separates internal cost rates from client-facing billable rates, with per-person defaults and per-project overrides. Teams can price work by project, member, or task and preserve dated rate history, so project cost and client billing stay aligned when vendor or labor costs change.
Track project costs, dated rates, and billable work in Everhour so purchase decisions connect to cleaner project margins and more accurate invoicing.
