Cancellation & Modifications

• Can an e-invoice be canceled partially/fully?

  You cannot cancel an e-invoice partially. If you must cancel the e-invoice, then it must be done completely or fully. 
  
  When you do this, you must report it to the IRN within 24 hours of the cancellation. If you try to cancel an e-invoice after that period, then you cannot use the IRN. Instead, you need to use the GST portal for cancellation, and it must be done manually. This has to be done prior to filing the returns.  When you cancel, you cannot re-use the invoice number, and a new one must be generated else the IRP will reject it. 

• How e-invoice works?

  e-Invoicing works in two parts - first is the interaction between the business and IRP, and the second is the interaction between the IRP, the GST/E-Way Bill Systems, and the Buyer. 
  
  The seller generates e-invoice and uploads it on the IRP. Once the IRP has verified the e-invoice, and IRN and QR code gets generated it is sent back to the seller and also gets updated in the e-way bill and GST system. The sellers sends the invoice attached with the IRN and QR code to the buyer. 

• How to modify e-invoice in GST portal?
  

  You cannot make any modification on the IRP. However, you can make required changes for the invoice details reported on the IRP through the GST portal when filing GSTR-1. As the IRP systems are interconnected with the GST system, as soon as the e-invoice is generated, the invoice details will be auto-populated in GSTR-1, which can be modified.

Business Benefits

• How does e-invoicing benefit businesses?

  Thanks to the complete interoperability of e-invoice data with the GST system, businesses can enjoy a range of benefits. For instance, the system pre-populates invoice details in GSTR-1returns and e-way bills, which helps to reduce reconciliation challenges. Additionally, it provides real-time visibility of invoices, allowing businesses to confirm their eligibility for Input Tax Credit (ITC) and eliminate the possibility of fake invoices. 

• How will e-invoicing curb tax evasion?
  

  Many benefits of e-invoicing exist and one of them is its ability to curb tax evasion. 
  
  With an e-invoice, the chances of editing invoices will be low because before any transaction is done, the invoice gets generated. Another reason why e-invoice system is helpful is that it ensures the authorities have information about all the transactions in real-time.  e-Invoicing greatly minimizes fake GST invoices and ensures that input tax credit is claimed on real GST invoices due to automation and thorough checks. If someone tries to claim a fake tax credit, then it is easy for GSTN to track them.
