Purchase Order vs Invoice: Key Differences & Templates

Purchase orders and invoices are super important for a smooth procurement process. It’s easy to mix them up, but they serve different purposes for the buyer and seller.

Understanding the differences between purchase orders and invoices can help you stay organized and comply with legal requirements. They are also crucial when it comes to tracking sales and managing cash flow, which is important for business success.

In this guide, we’ll discuss the differences between a purchase order vs invoice, the benefits of using a purchase order and invoice, plus customizable templates to help you create one for your business.

Quick Read

  • A purchase order (PO) is a document issued by the buyer to the seller indicating interest in purchasing goods and services. It contains the details of the requested goods or services, including quantities, prices and delivery terms.
  • An invoice is a billing document issued by the seller to the buyer after the delivery of goods or services. It is used to request payment for the transaction and includes the specifics of the purchase, prices, and the total amount owed.
  • The four main types of purchase orders are Standard PO, Planned PO (PPO), Blanket PO (BPO) and Contract PO (CPO).
  • Purchase orders and invoices are crucial for documentation, procurement management, tracking cash flow and dispute resolution.
  • Visme offers a variety of customizable purchase order and invoice templates and intuitive features that allow businesses to create professional-looking purchase orders and invoices.

 

What is a Purchase Order?

The purchase order (PO) is a formal request by the buyer for the vendor to supply the specified goods or services.

This document outlines the client’s expectations for the products or services, including quantity, pricing and terms. The purchase order then goes to the supplier (or the business) for approval, at which point it becomes legally binding.

What is a Purchase Order Number?

Each purchase order (PO) is assigned a unique identifying number, which serves several important purposes, such as: The PO number helps with:

  • Managing and tracking purchases, as well as for record-keeping.
  • Ensuring that purchase orders can be quickly located, verified and reconciled with the corresponding invoices.

What’s Included in a Purchase Order?

A standard purchase order (PO) often includes the following:

  • Order date
  • Payment terms and conditions
  • Delivery date and payment deadlines
  • Applicable taxes
  • Contact information for the buyer and seller
  • Billing address
  • Unique PO number

 

Types of Purchase Order

1. Standard Purchase Order (PO)

Standard purchase orders are the most commonly used type of purchase order. They are used for sporadic, one-off purchases and include detailed information including the list of items, quantities, prices, delivery dates, and locations.

2. Planned Purchase Order (PPO)

A planned purchase order contains the same information as a standard PO, except it omits the delivery details. PPOs establish a commitment to purchase certain items at agreed quantities and prices. However, the buyer must confirm the delivery schedule later through “schedule releases” against the PPO.

3. Blanket Purchase Order (BPO)

Blanket purchase orders are similar to PPOs, but they omit the item quantities, prices and delivery details. A BPO is typically used when unexpected purchasing situations make it challenging or impossible to give specific requirements.

4. Contract Purchase Order (CPO)

A contract purchase order (CPO) does not include any specifics about the items to be purchased. Instead, it solely establishes the legal terms and conditions that will govern all future purchase orders placed between the buyer and supplier. CPOs facilitate ongoing business relationships through high-level purchasing agreements.

 

What is an Invoice?

An invoice is a document issued by a seller to a buyer to request payment for products or services provided. It includes details such as the description of services provided, total cost, due date, payment method and other relevant details.

Vendors can deliver invoices in either paper or electronic format. The vendor sends an invoice to the buyer after delivering the product or service, specifying the amount due and the payment terms. This gives the customer clarity into the outstanding balance and the timeline for completing the transaction.

What’s Included in an Invoice?

A typical invoice contains the following:

  • Unique invoice number
  • Seller’s name, address and contact information
  • Buyer’s name, address and contact information
  • Date of product/service delivery
  • Date the invoice was issued
  • Itemized list of products/services, including quantity, unit cost and total cost
  • Total amount due, including any applicable taxes
  • Payment terms
  • Available payment options
  • Purchase order number
  • Terms and conditions (e.g., late fees, return policies)

 

Purchase Order vs. Invoice: Key Differences & Benefits

Sales Order vs Purchase Order vs Invoice

A sales order is a document created by a seller when a customer places an order. This document specifies the purchased items or services, quantities, prices, and terms of the sale.

In contrast, a purchase order is a document created by the buyer and sent to the seller. It communicates the buyer's intent to purchase goods or services and specifies the details of the transaction, such as the items, quantities, prices and delivery terms.

Finally, an invoice is a billing document issued by the seller to the buyer after the goods or services have been provided. The invoice requests payment for the transaction and includes the specifics of what was purchased, the prices and the total amount owed.

Benefits of Using a Purchase Order or Invoice?

Here are a few benefits of using a purchase order and an invoice:

Helps to Maintain Cash Flow

Cash flow issues are the reason 82% of small businesses fail. By sending out invoices promptly, sellers can decrease the chances of payments being delayed or overlooked, as well as avoid any potential cash flow problems.

Reviewing past purchase orders and invoices can also assist buyers in managing their expenses and verifying that new purchases are in line with their budgets and needs.

Crucial for Financial Records and Documentation

Your purchase orders and invoices offer thorough records of your transactions. These records are important for addressing billing discrepancies, conducting audits or claiming tax deductions.

Assists in Inventory Management

Placing a purchase order with your supplier allows you to monitor the arrival of necessary goods to your store. By doing so, you can verify that the invoice, purchase order, and products received are in sync before giving your approval and paying the invoice.

Proof of Transaction To Resolve Billing Disputes

In the event of a billing dispute between a seller and a buyer, the purchase order and invoice can give detailed evidence which can help to quickly resolve the disputes.

Invoice vs Receipt FAQs

A purchase invoice is a document that records a business transaction where a good or service has been purchased.

It typically includes details such as the items or services purchased, the quantity, the price per item, the total amount due and the payment terms. The purchase invoice serves as a record of the transaction and is used to request payment from the customer or client.

No, a purchase order and a bill are not the same. A purchase order is a document issued by a buyer to a seller, requesting the delivery of specific goods or services at an agreed-upon price.

It outlines the details of the order, such as the items, quantities and pricing, but does not represent a payment request.

In contrast, a bill is a document issued to the buyer after the goods or services have been provided. The bill requests payment from the buyer for the items or services delivered and it includes the total amount owed, payment terms and any other relevant details.

While a purchase order precedes the bill, the two documents work together to facilitate the procurement and payment process between the buyer and seller.

The purchase order typically comes before the invoice in the following sequence:

  1. The buyer issues a purchase order to the seller, requesting specific goods or services at agreed-upon terms.
  2. The seller fulfills the order by providing the requested goods or services.
  3. The seller then issues an invoice to the buyer, requesting payment for the delivered items or completed services.

Yes, it is possible to issue an invoice without a preceding purchase order. There are a few scenarios where this can occur:

  • Ongoing or Recurring Services
  • Emergency Purchases
  • When the buyer and seller have an established business relationship
  • Smaller or routine transactions.

There are a few situations where it may not be necessary or practical to use a purchase order:

  • Small, Informal Purchases: For very small, one-time purchases of low-cost items or services, the overhead of generating a purchase order may outweigh the benefits. In these cases, an invoice alone may suffice.
  • Recurring or Subscription-Based Services: For ongoing services that a business subscribes to regularly (e.g. software subscriptions, monthly retainers, etc.), it may be more efficient to simply invoice the customer rather than create a new purchase order each time.
  • Emergency or Rush Situations: When there is an urgent need for a product or service, it may not be feasible to go through the formal purchase order process. In these cases, invoicing directly is more time-efficient.
  • Established Vendor Relationships: If a business has a long-standing, trusted relationship with a particular vendor, the purchase order step may be unnecessary, especially for routine or small-scale transactions.
  • Informal or Verbal Agreements: In some cases, a purchase may be made based on a verbal agreement or informal communication with no formal, documented purchase order.

After a purchase order (PO) is sent to a vendor, the following typically happens:

  • The vendor receives the purchase order and reviews the details.
  • The vendor proceeds to fulfill the order by preparing and shipping the goods.
  • Once the order has been fulfilled, the vendor will issue an invoice to the buyer.
  • The buyer verifies that the invoiced items and amounts match the PO and then proceeds to pay the invoice.
  • The buyer makes the payment to the vendor, typically within the agreed-upon payment terms.
  • Both the buyer and vendor maintain records of the purchase order.

The purchase order is typically issued by the buyer or purchasing organization, not the seller or vendor.
