What is Proforma Invoice?

A proforma invoice, defined as an early version of a bill, follows a GST-compliant format and is sent by sellers to buyers as a preview before delivering goods or services. This document, acting like a shopping list, includes details such as product descriptions, estimated costs, and important terms. Proforma invoices are crucial for businesses, ensuring both parties agree on what’s being sold and at what cost, serving as a pre-deal agreement. The importance of proforma invoices lies in their role in avoiding misunderstandings, planning transactions, and maintaining transparency, especially in international trade. In the context of GST, proforma invoices help businesses adhere to regulations, providing estimates before the actual transaction, acting as a ‘before’ snapshot for planning and budgeting.

Understanding GST and Its Relevance to Invoices

GST, short for Goods and Services Tax, is a type of tax applied when you buy goods or services. Introduced by the government to simplify the tax system, it replaces various confusing taxes and helps prevent tax evasion. For example, if you buy a mobile phone for Rs. 10,000 with an 18% GST rate, the GST amount is Rs. 1,800, making the total cost Rs. 11,800. This GST amount is paid to the government by the seller. Invoices are relevant to GST as they show the tax component, ensuring pricing transparency and compliance with tax regulations when a business issues them for products or services.

For example, an invoice for a product costing Rs. 10,000 with an 18% GST rate would include the following:

  1. Product Cost: Rs. 10,000
  2. GST Amount: Rs. 1,800 (18% of Rs. 10,000)
  3. Total Invoice Amount: Rs. 11,800 (Product Cost + GST Amount)

Including the GST details on the invoice helps both the buyer and the seller understand the tax implications of the transaction. It also ensures that the correct amount of GST is collected by the seller for remittance to the government. 

Proforma Invoice Essentials

A proforma invoice, like a detailed shopping list before you buy something, should have:
