A GST invoice is an essential document that includes important information related to a transaction between two parties. The invoice assesses the amount of GST payable on a particular sale and serves as proof of supply. The GST invoice should include essential details such as the name, address, and GSTIN of the supplier and recipient, the date of the transaction, a unique invoice number, a description of the goods or services supplied, the quantity and value of the goods or services, and the applicable GST rate and amount. 

In addition to these details, there are certain specific requirements for different types of transactions, such as export invoices, invoices for supplies to SEZs, and invoices for reverse charge transactions. Failure to include the required information in a GST invoice can lead to penalties and interest charges. Therefore, it is important for businesses to ensure that their invoices are complete and accurate to avoid any compliance issues.
