Invoicing Under GST


As a GST registered dealer, you are required to provide GST Invoices, also known as GST bill to your clients.

Here, we will be covering the following aspects of GST Invoices:

What is a GST Invoice?

An invoice or a GST bill is a list of goods sent or services provided, along with the amount due for payment.

Under the GST regime, an “invoice” or “tax invoice” means the tax invoice referred to in section 31 of the CGST Act, 2017. This section mandates issuance of invoice or a bill of supply for every supply of goods or services. It is not necessary that only a person supplying goods or services need to issue invoice. 

Who should issue GST Invoice?

If you are a GST registered business, you need to provide GST-complaint invoices to your clients for sale of good and/or services.

Your GST registered vendors will provide GST-compliant purchase invoices to you

What are the mandatory fields a GST Invoice should have?

A tax invoice is generally issued to charge the tax and pass on the input tax credit. A GST Invoice must have the following mandatory fields-

  1. Invoice number and date
  2. Customer name
  3. Shipping and billing address
  4. Customer and taxpayer’s GSTIN (if registered)**
  5. Place of supply
  6. HSN code/ SAC code
  7. Item details i.e. description, quantity (number), unit (meter, kg etc.), total value
  8. Taxable value and discounts
  9. Rate and amount of taxes i.e. CGST/ SGST/ IGST
  10. Whether GST is payable on reverse charge basis
  11. Signature of the supplier

**If the recipient is not registered AND the value is more than Rs. 50,000 then the invoice should carry:

  • name and address of the recipient,
  • address of delivery,
  • state name and state code

By when should you issue invoices?




The GST Act has defined time limit to issue GST tax invoice, revised GST bill, debit note, and credit note. Following are the due dates for issuing an invoice to customers:

What are other types of invoices?

a. Bill of Supply

A bill of supply is similar to a GST invoice except for that bill of supply does not contain any tax amount as the seller cannot charge GST to the buyer.

A bill of supply is issued in cases where tax cannot be charged:

  • Registered person is selling exempted goods/services,
  • Registered person has opted for composition scheme

Invoice-cum-bill of supply

As per Notification No. 45/2017 – Central Tax dated 13th October 2017 If a registered person is supplying taxable as well as exempted goods/ services to an unregistered person, then he can issue a single “invoice-cum-bill of supply” for all such supplies.

b. Aggregate Invoice

If the value of multiple invoices is less than Rs. 200 and the buyer are unregistered, the seller can issue an aggregate or bulk invoice for the multiple invoices on a daily basis.

For example, you may have issued 3 invoices in a day of Rs.80, Rs.90 and Rs. 120. In such a case, you can issue a single invoice, totaling Rs.290, to be called an aggregate invoice.

c. Reverse Charge Invoice

A taxpayer liable to pay tax under Reverse Charge Mechanism (RCM) has to issue an invoice for goods or services or both received by him. The receiver shall mention the fact that the tax is paid under RCM. In addition, they have to issue a payment voucher while making payment to the supplier.

d. Debit and credit note

A debit note is issued by the seller when the amount payable by the buyer to seller increases:

  1. Tax invoice has a lower taxable value than the amount that should have been charged
  2. Tax invoice has a lower tax value than the amount that should have been charged

A credit note is issued by the seller when the value of invoice decreases:

  1. Tax invoice has a higher taxable value than the amount that should have been charged
  2. Tax invoice has a higher tax value than the amount that should have been charged
  3. Buyer refunds the goods to the supplier
  4. Services are found to be deficient

Can you revise invoices issued before GST?

Yes. You can revise invoices issued before GST. Under the GST regime, all the dealers must apply for provisional registration before getting the permanent registration certificate.

This applies to all the invoices issued between the date of implementation of GST and the date your registration certificate has been issued.

As a dealer, you must issue a revised invoice against the invoices already issued. The revised invoice has to be issued within 1 month from the date of issue of the registration certificate.
