Fundamentally, invoices are documents which notify a buyer of the legal obligation to pay money against buying of goods/services
 
Credit matching and reconciliation depends on the invoices uploaded by tax payers. Businesses have to make sure that invoice formats obey the GST guidelines. The government has notified invoicing rules along with a template of invoice GST INV-01. It covers the elements such as supplier’s details, GST tax rates etc that one should include in a bill.

In the GST regime, a trader has to issue two types of invoices.

1. Tax Invoices

A registered taxable person issues tax invoice on supply of taxable goods and/or services. The tax invoice is issued to registered dealer. The registered dealer can use it to claim Input Tax Credit.
 
Number of Copies:
The supplier has to issue three copies of the invoices on supply of goods.

 *IRN stands for Invoice reference Number. The supplier can get an IRN from the common portal (GSTN) by uploading a tax invoice issued by him. The IRN will be valid for 30 days from the date of uploading.
A service provider has to issue only two copies of a bill. An original copy is for the recipient of service and a duplicate copy is for the supplier’s record.

2. Bill of Supply

Tax invoices are generally issued when tax is charged. In GST there are some instances where the supplier is not allowed to charge any tax. In such a case, a supplier cannot issue a tax invoice. Instead, the supplier will issue a Bill of Supply. If the bill amount is less than 200, it isn’t necessary to issue a Bill of Supply. The shopkeeper should prepare a combined bill of supply at the end of the business day for such supplies.
