Purchase Order vs Invoice: Main differences

Besides some common details, Purchase orders and Invoices are two separate terms with many differences.
Difference Between Purchase Order and Invoice

Function

A purchase order’s primary purpose is to outline the parameters of the agreement between the buyer and seller and to authorize a purchase. In addition, if approved by the seller, it becomes a binding legal document. An invoice, on the other hand, is a bill for products or services delivered and is employed to demand payment for those products or services.

Contents

A purchase order often includes information like the buyer’s contact details, the product or service being bought, the quantity being bought, the price of each item, the shipping date, and any unique requirements or conditions.

An invoice lists the goods or services that were delivered and accepted by the buyers, their respective costs, and the overall sum that is owed. Besides, sellers’ account details are crucial.

Formats

A purchase order is often a printed document that is signed by the buyer and the seller. While an invoice is issued from sellers with the seller’s signature. An invoice can be an electronic document sent to the customer by email or purchase order software.

Created time

A purchase order is created before the delivery of the goods or services. An invoice, on the other hand, is made following the completion of the delivery of the goods or services.

Payment

Unlike an invoice, which ensures payment for the products or services stated on it, a purchase order does not guarantee payment.

Tax

Taxes are not included in a purchase order, but they are on an invoice. Besides, an invoice will be legally used to prove a tax declaration.

How to manage your company’s Purchase Orders and Invoices?

In the beginning, when a business is still tiny and the volume of transactions is minimal, manually managing purchase orders and invoices are straightforward. But as the company expands, it becomes more difficult. It won’t help you much if you just understand how purchase orders and invoices differ from one another. Even with the use of an invoice template, manually producing numerous papers of this nature can be laborious and error-prone. Additionally, manual documents frequently become jumbled or, even worse, vanish, creating problems during disputes or audits.
Purchase order management

Luckily, nowadays, you can make your procurement a centralized, automated process with purchasing management software or application. Thanks to the advancement in technology, retailers of all sizes can streamline and improve the performance of these crucial procurement operations by integrating their procurement procedures into POS or ERP systems. These systems allow you to create digital purchase orders and invoices and send them to your clients in the quickest way as well as help you save a lot of money and time on papers. Besides, all data are linked in one single system so you will not be worried about making any mistakes.

Why are purchase orders and invoices important?

As a business, both documents are necessary for the purchasing process. You can’t just choose one when it comes to choosing between a purchase order and an invoice because both documents are equally crucial. Purchase orders provide much-needed explanation and help avoid disputes, although invoices appear to be crucial from a legal perspective.

The PO specifies the items that have been requested, the price, the anticipated delivery date, and the terms of payment for both the buyer and the supplier. The route of the PO includes approval, dispatch, delivery of the products or services, billing, matching, and closing from the time it is created. It becomes a legally binding document once it has been approved by the company and acknowledged by the vendor. POs give the vendor all specific instructions and assist purchasers in keeping track of budgets and a reliable paper trail. Without POs, the contract between the buyer and the supplier may be disputed and vulnerable to misunderstanding.

Whereas, invoices are needed to guarantee payment from clients after the goods are delivered. They specify exactly what you are paying for and how much you are spending. Companies can track payments and do official expense analyses using this data. In addition, an invoice by itself does not constitute a contract that is enforceable in court. But if the other requirements of a contract are satisfied, it can be a part of a binding agreement. In the event of an audit, invoices serve as tangible evidence of what your company paid for.

Purchase Order vs Invoice: Conclusion

In short, purchase orders and invoices are two important documents to any business in the long term. Although they may share some same information, they are quite different. Understanding them and knowing how to use them together with your current system will help you achieve a successful business.
