After e invoice login

Below is the main menu screen of NIC’s einvoice portal after a successful login:


From the above it is observed that there are five main options available:


The e-invoice menu on GST e invoice login contains the following sub-menus:

Upon successful cancellation, the system displays the message ‘e-invoice cancelled successfully!!’.

  • Bulk Upload: Rather than uploading details of each invoice one by one, an option has also been made available to upload multiple invoices in one single JSON file. The JSON can be generated by using the bulk converter tool that is also available on the website. Every invoice contained in the JSON will be assigned separate IRNs.
  • Cancel IRN: Where any mistake has been made in uploading details of an invoice, the generated IRN can also be cancelled within 24 hours of generating the same. Note that the IRN cannot be deleted and hence even the IRN of a cancelled invoice remains unique. The invoice that is to be cancelled can be found by entering the acknowledgement number.



  • Print e-invoice: The IRN/e-invoice number of the invoice that is required needs to be entered.


A sample of the print can be seen below:


MIS Reports

This option can be used to generate an MIS report. A list of invoices uploaded would be provided based on selected parameters and selected dates. This list can also be exported in excel format using the ‘Export to Excel’ tab.

User Management

A large business entity may have different people performing different roles in relation to invoices in an organisation. This portal allows controlling access of such users depending on their role.


As can be seen from the above figure, the various options provided are ‘Create Sub-User’, ‘Freeze Sub-User’, ‘Update Sub-User’ and ‘Change password’.  Each such sub-user will be given the following type of permissions:

  • Generate Invoice Reference Number
  • Cancel Invoice Reference Number
  • Report Generation of Invoice Reference Number


The sub-users would each be provided separate login credentials with their user ID being the same as that of the main user, except for the addition of a suffix. 

API Registration

In case the taxpayer chooses to directly integrate his ERP system or through GSP with the e-Invoicing system, click on ‘API Registration’ option > IP whitelisting to register your IP address with the portal.


Thereafter, select ‘Create API User’ under the ‘User Credentials’ option to register the GSTIN for the API interface and set the login credentials. In case the sister concern of your GSTIN has already registered for the API interface then the details thereof will be displayed. Enter the client ID and client secret to set the login credentials for your concern.

Change Password

The user can frequently change the password using this option.



It may be a tedious task to enter business details every time an e-invoice is prepared. Hence, it is possible to use this option to auto-populate certain fields while creating the e-invoice by pulling the data from the GST common portal.


E-Way Bill

The ‘e-way bill’ option can be used to fill up Part A of the e-way bill with only the vehicle number remaining to be entered in Part B.


Frequently Asked Questions

I am already registered on the GST common portal. Do I have to register separately on the e-invoice portal?

Yes, a separate GSTIN-based registration will need to be made on the e-invoice portal. However, the taxpayers who are registered on the e-way bill portal need not take separate registration on the e-invoice portal.

Should I compulsorily use einvoice portal?

If you are the applicable taxpayer notified to generate e-invoices, then you must compulsorily use einvoice portal.

Is partial cancellation of e-invoice possible?

No, e-invoices can only be fully cancelled within 24 hours of their generation.

What is the maximum number of sub-users that I can have?

Is it compulsory to assign sub-users?

No, it is not compulsory to assign sub-users. The decision regarding the number of sub-users, if any, must be taken by the taxpayer himself based on his business needs.

Why am I not able to generate reports for a particular period, i.e., select a start period and an end period?

Reports can only be generated for a particular day to ensure that the system does not take any additional burden and continues to perform smoothly. Hence, it is advisable to generate a report for each day separately if so needed.
