of disputes among transacting parties, improve payment cycles, reduction of processing
costs and thereby greatly improving overall business efficiency.

No. The seller will not be able to create IRN. This will only be returned by the IRP (portal).

Will it be possible for bulk uploading of invoices to IRP?

Yes. Bulk upload will be generally required by large taxpayers. Their ERP or accounting system will be designed in such a way that user can report invoices in bulk.

  • Though the option of obtaining IRN by entering invoice data via web-based screen will be available, that mode will be used rarely, e.g. by businesses who don’t use any ERPs/Accounting/Billing Software and have very few invoices to report.
  •  Ultimately this will be replaced by mobile app-based tool for such taxpayers.

Why is an e-invoice standard/schema required?

  • Presently, businesses are preparing/generating invoices in their respective ERPs/Accounting/Billing Software. The e-invoice generated by one is not understood by the other, thereby necessitating data entry efforts and consequent errors and reconciliation problems.
  • ‘Schema’ acts as uniform standard for ERP/ Billing/Accounting software providers to build utility in their solution/package to prepare e-invoice in notified standard thereby ensuring e-invoice generated by any ERP/Accounting and Billing Software is correctly understood by another ERP/Accounting software. This is also required for ensuring uniformity in reporting to IRP.
  • Schema ensures e-invoice is ‘machine-readable’ and ‘inter-operable’, i.e. the  invoice/format can be readily ‘picked up’, ‘read’, ‘understood’ and further processed by different systems like Oracle, Tally, SAP etc.

  • Data for fields marked as ‘Mandatory’ have to be provided compulsorily.
  • A mandatory field not having any value can be reported as NIL.

Based on this report, the system will declare whether tax payer is qualified for production access or not.

Which is the algorithm used for encryption and decryption of data?

The asymmetric algorithm (RSA/ECB/PKCS1Padding) and symmetric algorithm AES256 (AES/ECB/PKCS5Padding) along with SEK is used to encrypt the request payloads of the POST API methods and to decrypt response payloads. It may be noted that SEK is generated and passed by the e-invoice system while sending the authentication token.

Whether e-invoice generated is also required to be signed again by the taxpayer?

  1. Signing of invoice is required by the rules notified by the Government of India. A placeholder for digital signature has been added in the e-invoice schema and hence if a signed e-invoice is sent to IRP, the same will be accepted.
  2. The e-invoice will be digitally signed by the IRP after it has been validated. The signed e-invoice along with QR code will be shared with creator of document as well as the recipient.
  3. Once it is registered, it will not be required to be signed by anyone else.

Can the seller place their LOGO in the e-invoice template?

  1. There will NOT be a place holder provided in the e-invoice schema for the company logo.

E-invoice system is showing my old email id or mobile number. How should I get it changed?

E-invoice system is using the email id and mobile number, registered by the taxpayer on the GST Common Portal, for communication purpose. If it is old, get is updated with latest on the common portal and communicate to us at so that we can cross-verify and update on the sandbox for accessing the credentials. If you are a GSP, then get it updated with GSTN and request them to communicate to us so that it can be updated.

My one business unit has GSTIN in each state based on same PAN. Can I use same API credentials to access to the API system?

There are two types of API credentials – Client Id and Client Secret, and Username and Password. Client Id and Client Secret is provided to the notified tax payer and the tax payer can use it for all the business units registered in different states, based on the same PAN. Whereas the Username and Password is created for each GSTIN. That is, one business, registered in different states, need to create separate username and password for each registered unit/GSTIN.

What if email id and mobile number is not matching?

Make sure you use the email id and mobile number entered by you in the GST portal.

e-Invoice/ Generate IRN API allows for maximum of 1000 line items per document whereas Generate e-Way Bill API allows maximum of 250 line items per document. Can you please confirm whether Generate e-way bill API will be changed now to sync allowing of line item count in e-way Bill APIs?

e-Invoice will have 1000 line items, and when the e-way bill generated from it, e-way bill have high value 250 items with total invoice value. This is followed in current e-way bill system also.

Could you please let us know if taxpayer system could generate the IRN on their own using the SHA256 algorithm logic (or) we need to mandatorily get the information from IRP.

Just generation of IRN is not the goal of the e-Invoice system. Registering the invoice with the IRP is the actual requirement (Given the logic of generation of IRN, anybody can generate it, but unless it is registered, it has no authenticity). As the IRP anyway has to generate the IRN (atleast to check whether tax payer generated IRN is correct), there is no need to generate IRN by tax payer.

Should there be a space provided for the QR Code in the e-invoice?

  • The QR code will be provided to the seller once he uploads the invoice into the Invoice Registration system and the same is registered there.
  • Seller must print the QR code on the printed Invoice.

Please suggest whether QR Code of signed data needs to be printed or QR Code of decoded data must be printed for B2B(Business-to-Business) E-Invoice PDF to be issued/ maintained/ shared by suppliers having turnover of more than 500 crore with their buyers?

Signed QR Code data, passed as the response of IRN generation, has to be printed along with the signature on the invoice. You can see these QR code on the web version of e-invoice system that is, going to be released shortly.
