difference between pi & po

Among the everyday business transactions, the two most essential invoices that every business has to deal with, regularly, include the purchase invoice and the sales invoice. A sales invoice is given by a seller to its customers when the business makes a sale, and it is the proof of the amount due to the company by the customers. On the other hand, the purchase invoice is its complete opposite. 

Let’s understand it in detail. 

What is a Purchase invoice? 

A purchase invoice is an invoice issued by the buyer of goods. It is a financial document that indicates the details of a purchase that has been made, including the items, amount, date of payment, etc. While its contents are similar to that of a sales invoice, it indicates that a purchase has been made for a particular amount.

A purchase invoice is usually issued after the purchase order. This means that you can generate a purchase invoice for the purchases you make from your supplier once the transaction is complete. 

Components of a purchase invoice

Invoice number: Much like the sales invoice, a purchase invoice also has a unique number to identify and relate it to a purchase order. 

Purchase order number: Every purchase invoice is generated as a fulfilment of a purchase order and has the associated Purchase Order number. Through the invoice, the transaction details can be traced back to the order to make sure that the transaction is completed correctly. 

Date of issue: The date on which the purchase order was fulfilled, and the invoice was generated is present on the purchase invoice. 

Vendor/Supplier details: The invoice also includes the details of the seller or the party that the goods are being purchased from, including their name, address, contact details and unique identification or GST number if available. 

Items description: The quantity, unit price, and the product code of the items purchased are the vital components of the purchase invoice. 

Total and tax: The total amount due by the buyer to the seller, including the taxes as applicable (GST), is also included in the issuance of a purchase invoice. 

What is a purchase order? 

A purchase order is a document used by the buyer to place an order with the suppliers as per his/her inventory requirements. A purchase order usually initiates a transaction. In some cases, when a business has regular customers, the buyer can issue a Standing Purchase Order (SPO) to ensure regular orders replenish inventory at regular intervals. 

Purchase Invoice (PI) vs Purchase Order (PO)

Here are some of the major differences between a PI and a PO: 

  • A PO is issued first in the chronological order of the documents. It is only once the order is placed, fulfilled, and payment settled (paid or settled to be paid in future), that the buyer issues a PI. 
  • A PO indicates the beginning of a business transaction. A PI indicates the end of the transaction. 
  • A PO may not have the price of the products or items involved in the transaction. On the other hand, a PI always contains the cost of the items and the total amount due by the buyer to the seller.
