In a nutshell, proforma invoices are issued to commit to supplying to a buyer goods or services at certain prices. A proforma is like a replica or a sample of an invoice that is going to be issued in the future for the same products / services. When you issue a proforma you will not need to actually pay GST for this document alone, as it will be paid for the GST invoice that you generate from it.
What is the meaning of proforma invoice?
A proforma invoice is a preliminary invoice of sales that a business sends to buyers in advance of a shipment or delivery of goods / services. This type of invoice typically declares the description, quantity, value, shipping details and charges of the products / services that will be purchased. Since most proforma invoices provide the buyer with a precise sale price, it also estimates any commissions or fees such as applicable taxes. Generally this document represents good faith and avoids exposing the buyer to unexpected or significant charges once the transaction has occurred.
What are the differences between invoice and proforma invoice?
An invoice (GST tax invoice) refers to a non-negotiable document raised by a seller and delivered to a buyer, containing details of products and services that are provided to him. This document is used as a payment request from the buyer and shows the indebtedness of the buyer towards the seller.

Some individuals might be confused by the difference between a proforma invoice and a regular tax invoice. To make it easier to understand and remember: a tax invoice demands payment from the buyer for the goods or services provided to him, while a proforma invoice is sent to a buyer on his request, before any shipment of goods might happen.
