What are other types of invoices?

Debit and Credit Note

In the event of the return of the goods, the purchaser makes a debit note if they have been purchased on credit. which means, at the time of sale on credit, the seller informs the buyer of the current outstanding debt. The reasons for raising the debit note include when:

  • The amount charged is higher than the taxable value in tax invoice.
  • Tax invoice has a lower tax value than the amount to have been charged.


A credit note is a commercial document issued by the supplier to inform the purchaser that a credit has been granted to the customer. Normally, the reasons for such credit include:

  • Error in the price mentioned in the invoice.
  • The buyer is overpaid.
  • Customers returned the goods or refused the service for some reason.
  • The goods were damaged during transit.

Bill of Supply

If the registered person either sells exempt goods / services or has opted for a composition scheme, the seller will issue a bill of supply instead of the GST invoice. The only difference between the GST bill and the bill of supply is that one has tax details and the other does not have a tax amount. i.e . bill of supply does not contain any tax amount as the seller cannot charge the GST to the buyer.

Aggregate Invoice

If multiple invoices are issued, the amount of which is less than Rs . 200, and the purchaser is unregistered, then an aggregate invoice may be issued by the seller instead of multiple invoices per day.
For Example, if 3 invoices amounting to Rs. 60, Rs. 105, and Rs. 80 have been issued. Then, a single invoice amounting to Rs. 245 can be issued.
