The taxpayer will continue to generate invoices in the normal course of business. However, the reporting of these invoices electronically has criteria.

The seller has to ensure that his accounting/billing software is capable of generating a JSON file of the final invoice. The seller can create a JSON file following the e-invoice schema and mandatory parameters by using the following modes:
The IRN (also known as hash) is a unique number which is generated by the e-invoice system using a hash generation algorithm. For every document submitted, a unique 64 character IRN will be generated. At present, the e-invoice system provides the two modes to generate the IRN (Invoice Reference Number), i.e offline and API. Notified taxpayers who need to generate e-invoices, can generate them using these options:
Using the offline tool
The invoices can be uploaded in the standard format and the IRN can be generated in one go. User can visit the e-invoice portal, and view the procedure for preparing a bulk upload request for IRNs at Help -> Tools -> Bulk Generation tools. Once the bulk upload request file has been prepared, the same needs to be uploaded in order to generate the IRNs. Once generated, the IRN form will all the details can be downloaded.
Using API (Through GSPs integration
Using API through GSP integration, system integration can be done through the help of registered GSPs (GST Suvidha Providers). Before using this mode, the API integration with the identified GSP will need to be tested in a sand-box environment. After the test, the GSP will need to submit the test summary report on the sand-box portal. The GSP will need to be registered on the e-invoice portal if not already registered. If the same GSP is being used as on the e-way bill portal, there is no need to register again, and the same login credentials can be used. An API user will need to be created by entering a username and password. Using these credentials, a token and request for the IRN can be generated.
Using API (Through direct integration)
Using API through direct integration, the taxpayers’ systems can be directly integrated. The API integration will need to be tested in a sand-box environment. After the test, the taxpayer will need to submit the test summary report on the sand-box portal. The taxpayer will need to get registered on the e-invoice portal if not already registered. If registered on the e-way bill portal, the same login credentials can be used. If the taxpayer is already integrated with API on the e-way bill system, the same API credentials can be used. If not, he will need to get API registration done using IP whitelisting. If a sister concern having the same PAN has already registered for API and has had IP whitelisting done, the same client-ID credentials can be used. However, the new API user will need to be registered.
Using API (Through an enabled sister concern’s GSTIN)
Systems can be integrated using API, through the sister company of the taxpayer having the same PAN, if the same has been enabled for API. The API integration will need to be tested in a sand-box environment. After the test, the taxpayer will need to submit the test summary report on the sand-box portal. The IP used by the sister concern and the concerned taxpayer should be the same when accessing the e-way bill and e-invoice production APIs. The taxpayer will need to get registered on the e-invoice portal if not already registered on the e-way bill portal. If registered on the e-way bill portal, the same login credentials can be used. If the taxpayer is already integrated with API on the e-way bill system, the same API credentials can be used. If not, he will need to create a new API user.
E-way Bill API-enabled Taxpayers
System integration using API can be done for e-way bill-enabled taxpayers. The taxpayer will need to test the API integration in a sand-box environment. After the test, the taxpayer will need to submit the test summary report on the sand-box portal. If the taxpayer is already API-enabled on the e-way bill system, the same credentials can be used. There is no need for any further steps.
The e-invoice system will generate the IRN, and then digitally sign the e-invoice and the QR code (quick response code). The QR code will enable a quick view, and validation and access of the invoices from handheld devices. The QR code will consist of the following parameters:
The digitally signed QR code will have the unique IRN (hash) which can be verified on the central portal, as well as by offline apps. This will be helpful for tax officers who need to check invoices in places where internet connection may not be available, such as on highways.
The signed e-invoice data will be sent to the GST system where GSTR-1 of the supplier and GSTR-2B/2A of the buyer will be updated based on the details entered in the invoice. Wherever applicable, details of invoices will be used to update ‘Part A’ of the E-Way Bill. As a result, only vehicle number needs to be entered in ‘Part B’ of the E-Way Bill system to create an E-Way bill.
