The supplier shall issue the GST invoice for all the supply of goods and services on exceeding the value of Rs.200. If the supplier registered with GST for providing goods and services, then, the supplier must provide invoice irrespective of the taxable value, if demanded by the customer.

The time for issuing GST invoice differs based on the type of supply, i.e., goods or services.

However, in some cases, the supplier shall issue a tax invoice at the time of delivery of goods or while making the goods available to the recipient. In such cases, a delivery challan can be issued by the supplier to generate GST Eway bill and transport the goods to the recipient without a tax invoice.

For services, the supplier shall issue the tax invoice before or after providing the service, but not later than thirty days from the date of providing of service.
