Key Differences Between the New GST Invoice Format and Old Invoice Format

Invoice formats across the world have certain universal elements that are the same as the date of invoice, name, and address of the supplier and recipient, description of goods, quantity, the total value of supply, the taxable value of supply, rate of tax, amount of tax and final value.

Under GST, GSTIN of the supplier is mandatorily required to be mentioned in the tax invoice along with a consecutive serial number that is unique for each financial year. Hence, businesses must adopt an invoice numbering format that takes into account the GST requirements. Small businesses can adopt an invoice number format starting with the financial year like 2022-XXXX, wherein the XXXX could be numerals for easily keeping track of the number of invoices issued by the business in a financial year. There is no requirement that the numbering starts from 1. Hence, the business can determine a starting number as per their requirements and consecutively number the invoices from the starting number. Large businesses, on the other hand, can adopt a serial numbering which includes alphabets to increase the number of available invoice numbers and to handle complexities like branch accounting.
