Learn how to create professional purchase orders
A purchase order is the backbone of organized procurement. Whether you are ordering raw materials for manufacturing, supplies for your office, or services from a contractor, a formal purchase order creates a clear, documented agreement between buyer and supplier. It eliminates the ambiguity of verbal agreements and email threads by putting quantities, prices, and terms into a single authoritative document.
For growing businesses, purchase orders are essential for maintaining budget control and accountability. They create an approval trail that prevents unauthorized spending and make it easy to reconcile what was ordered against what was delivered and invoiced. Without purchase orders, businesses often face disputes over pricing, receive incorrect quantities, or discover budget overruns only after the fact.
Bilto's free invoice generator makes it easy to create purchase order-style documents without specialized procurement software. Enter your company as the sender and the supplier as the recipient, list the items you need with quantities and prices, add your PO number and delivery terms in the notes field, and download a clean PDF to send to your supplier.
What is a Purchase Order?
A purchase order (PO) is a commercial document issued by a buyer to a seller, indicating the types, quantities, and agreed prices for products or services. It is a formal offer to purchase that, once accepted by the supplier, becomes a legally binding contract between the two parties.
Purchase orders serve multiple purposes in a business. They authorize the supplier to deliver goods, establish the price that the buyer has agreed to pay, and create a reference document that both parties can use to track the transaction from order through delivery and payment. When the supplier sends an invoice, it typically references the PO number, making it straightforward to match invoices against original orders during the accounts payable process.
The legal significance of purchase orders should not be understated. In many jurisdictions, an accepted purchase order constitutes a binding agreement. This means that if a supplier accepts your PO, they are obligated to deliver the specified goods at the agreed price, and you are obligated to pay for them upon satisfactory delivery. This mutual commitment protects both parties and provides a foundation for resolving any disputes that may arise.
Key Components of a Purchase Order
A complete purchase order should contain sufficient detail to leave no room for misunderstanding. Include the following elements:
- PO number — a unique sequential identifier used for tracking across your organization and with the supplier
- Date of issue — when the purchase order was created and sent to the supplier
- Buyer information — your company name, address, contact person, and billing details
- Seller/supplier information — the vendor's business name, address, and contact details
- Item descriptions — clear, specific descriptions of each product or service being ordered, including part numbers or SKUs where applicable
- Quantities and units of measure — the exact amount of each item required, specified in appropriate units (pieces, kilograms, hours, etc.)
- Unit prices and line totals — the agreed price per unit and the extended total for each line item
- Delivery terms — the required delivery date, shipping method, and any specific delivery instructions
- Payment terms — when and how payment will be made (e.g., Net 30, Net 60, upon delivery)
- Shipping address — the physical location where goods should be delivered, which may differ from the billing address
- Authorization — the name and signature of the person authorized to approve the purchase on behalf of the buying organization

Purchase Order vs Invoice
Purchase orders and invoices are two sides of the same transaction, but they originate from different parties and serve different purposes. Understanding this distinction is key to maintaining clean financial records.
A purchase order is created by the buyer and sent to the supplier. It says: "We want to buy these items at these prices. Please confirm and deliver." It initiates the transaction and establishes the terms before any goods change hands.
An invoice is created by the supplier and sent to the buyer after the goods or services have been delivered. It says: "Here is what we provided and what you owe." The invoice typically references the PO number so the buyer's accounts payable team can verify that the invoice matches the original order.
This PO-to-invoice workflow creates a three-way match that is fundamental to sound procurement practices: the purchase order (what was ordered), the delivery receipt (what was received), and the invoice (what was billed). When all three documents agree, the payment can be processed with confidence. Discrepancies trigger a review process that catches errors, overcharges, and fraud before money leaves your account.
Types of Purchase Orders
Standard Purchase Order
The most common type. A standard PO is a one-time order for specific goods or services with defined quantities, prices, and delivery dates. It is used for non-recurring purchases where the buyer knows exactly what they need.
Blanket Purchase Order
A blanket PO covers recurring purchases from the same supplier over a set period, typically a quarter or a year. It establishes agreed pricing and terms but allows the buyer to place individual delivery orders (releases) as needed. This is common for office supplies, raw materials, and maintenance services.
Contract Purchase Order
A contract PO establishes terms and conditions for future purchases without specifying exact quantities or delivery dates. It functions as a framework agreement that is referenced by subsequent standard POs. Large organizations often use contract POs to lock in pricing with strategic suppliers.
Planned Purchase Order
A planned PO is similar to a standard PO but with tentative delivery dates and quantities. It signals the buyer's intent to purchase and allows the supplier to begin preparation, but the final details are confirmed closer to the delivery date. This is useful in manufacturing environments where production schedules drive procurement timing.
Benefits of Using Purchase Orders
Budget Control
Purchase orders commit spending before it happens, giving finance teams visibility into upcoming expenses. This prevents budget overruns and ensures that all purchases align with approved budgets.
Dispute Prevention
When both parties have a documented agreement on quantities and prices, disputes about what was ordered and at what cost become rare. The PO serves as the single source of truth for the transaction.
Audit Trail
Purchase orders create a verifiable paper trail from requisition to payment. This is invaluable during financial audits and helps demonstrate compliance with internal procurement policies and external regulations.
Inventory Planning
By documenting what has been ordered and when it is expected to arrive, purchase orders help warehouse and operations teams plan storage, staffing, and production schedules around incoming deliveries.
Streamlined Accounts Payable
When invoices reference PO numbers, the accounts payable team can quickly verify that charges match the original order. This three-way matching process speeds up payment approvals and catches billing errors before they result in overpayments.
Frequently Asked Questions

Yes, Bilto is completely free to use. You can use the invoice generator to create purchase order-style documents and download them as PDFs at no cost.
Is a purchase order legally binding?
A purchase order becomes a legally binding contract once the supplier accepts it. Before acceptance, it is a formal offer from the buyer. Once accepted, both parties are obligated to fulfill the terms outlined in the PO, including quantities, prices, and delivery timelines.
What is the difference between a purchase order and an invoice?
A purchase order is created by the buyer and sent to the supplier to authorize a purchase. An invoice is created by the supplier and sent to the buyer to request payment after goods or services have been delivered. The PO comes first and the invoice follows, often referencing the original PO number.
Do small businesses need purchase orders?
While not legally required for most small businesses, purchase orders bring significant benefits even at small scale. They create clear documentation of what was ordered and at what price, reducing the risk of disputes, duplicate orders, and budget overruns. They also simplify bookkeeping and tax preparation.
