What is a Purchase Order?
A purchase order is a commercial source document that is issued by a business’ purchasing department when placing an order with its vendors or suppliers. The document indicates the details on the items that are to be purchased, such as the types of goods, quantity, and price. In simple terms, it is the contract drafted by the buyer when purchasing goods from the seller.
Steps in Ordering
1. Buyer creates a purchase requisition
Before sending out the purchase order to the supplier, the first step is to create a purchase requisition. This is a document issued within the company to the purchasing department to keep track of the goods ordered.
The purchase requisition also helps the company keep an account of their expenses. The PO is created only after the purchase requisition is approved by the authorized manager.
2. Buyer creates a purchase order
When the goods that need to be purchased are agreed upon, the purchase order is created. The PO lists the date of the order, FOB shipping information, discount terms, names of the buyer and seller, description of the goods being purchased, item number, price, quantity, and the PO number.
The PO number is a unique number associated with a certain order. It serves two purposes. One is to ensure that the goods ordered match the ones that are received. Secondly, the PO number is matched to the invoice to make sure the buyer is charged the right amount for the goods.
3. Seller accepts (or rejects) purchase order
At the bottom of the purchase order is a dotted line for the authorized manager of the seller to sign off on the order. The PO includes all the details about the transaction and what the buyer expects to receive. Once the seller receives the PO, they have the right to either accept or reject the document. However, once the PO is accepted, it becomes a legally binding contract for both parties involved.
4. Buyer records purchase order
Once the order has been placed, the purchase order remains “open.” An open purchase order is a PO where the order is placed but the goods have not yet been received, or it can mean that only part of the order has been received. Either way, it signifies that the delivery of the goods is not complete.
Benefits of Purchase Orders
1. Avoids duplicate orders
Purchase orders bring several benefits to a company. The most important is that it helps avoid duplicate orders. When a company decides to scale the business, POs can help keep track of what has been ordered and from whom.
Also, when a buyer orders similar products, matching the invoices can be difficult. The PO serves as a check for the invoices that need to be paid.
2. Keeps track of incoming orders
In addition, POs help keep track of incoming orders, and a well-organized purchase order system can help simplify the inventory and shipping process.
3. Serves as legal documents
Purchase orders serve as legal documents and help avoid any future disputes regarding the transaction.
How Does the Supplier Use the Purchase Order?
Purchase orders play a major role in the inventory management process. When the supplier receives the PO, they will take the items listed in the PO from their inventory. The PO helps keep a record of the inventory on hand and identify any discrepancies between the values shown in the records and the actual stock.
Additionally, the supplier needs the PO to fill the order correctly. The buyer will also be charged by the supplier based on the payment terms agreed upon in the PO.
Purchase Order vs. Invoice
The purchase order is a document generated by the buyer and serves the purpose of ordering goods from the supplier. The invoice, on the other hand, is generated by the supplier and shows how much the buyer needs to pay for goods bought from the supplier. The PO is a contract of the sale while the invoice is the confirmation of the sale.
Purchase Order vs. Sales Order
While the purchase order shows what goods were ordered from the supplier, the sales order is generated by the supplier and sent to the buyer. It signifies the confirmation or approval of the sale. Nowadays, the PO process is no longer paper-based, and the buyer usually sends its suppliers an electronic PO. This is done using the PO module in ERP software. It helps speed up the purchasing process while decreasing the chance of error.
