For claiming input tax credit it is important to issue and receive GST compliant invoices.

What is Bill Of Supply ?

In some cases the supplier is not allowed to charge any taxes hence he won’t be able to generate a normal tax invoice, in such cases a Bill of Supply is issued.

Debit Note

When there is an increase in the price of Service /Goods provided before GST and the same is applicable to GST then the supplier needs to issue a supplementary invoice to the recipient within 30 days from the date of price increase. The format of debit note is similar to tax invoice only the nature of invoice need to be mentioned such as Debit Note etc.

Credit Note

If there is a price reduction and GST needs to be charged in other past transactions a credit note is issued, and as mentioned above it needs to be issued on or before 30th of September following the end of the financial year or on the date of filing the annual return for that financial year.
