GST Invoice

Invoicing is a crucial activity for any business, irrespective of type and size. Businesses should be careful while generating invoices as every transaction enters into books of accounts through this activity. Further, after introducing the Goods and Services Tax (GST), registered businesses must issue GST invoices, also known as GST bills.

A registered person must issue a tax invoice before, or at the time of removal of goods for supply to the recipient. For supplying services, GST invoices can be issued before, at, or even after the time of supply. Further, e-Invoicing system is also being implemented in a phased manner that requires certain more mandatory fields.
