What is e-invoicing

Under GST, e-invoicing means reporting your B2B invoices to a government portal, which validates them and returns a unique reference number and QR code. It is not a separate invoice but a way of registering your invoices with the system. It improves accuracy and reduces fraud.

Who needs to do it

e-Invoicing applies to GST-registered businesses whose turnover crosses a notified threshold. This threshold has been progressively lowered over time, bringing more businesses into its scope. If your turnover is near or above the current limit, you should check whether e-invoicing applies to you.

How the process works

  • You generate your invoice in your billing system
  • The invoice details are reported to the invoice registration portal
  • The portal validates it and returns a unique reference number and QR code
  • The validated e-invoice flows into your GST returns and the buyer's records

Why it matters

e-Invoicing reduces mismatches, makes input tax credit smoother for your buyers, and keeps you aligned with the increasingly automated GST system. With stricter ITC matching in force, correct e-invoicing helps avoid blocked credits and disputes.

Getting ready

If e-invoicing applies to you, ensure your billing software supports it, your invoice data is accurate, and your team understands the workflow. Errors in e-invoices can cause problems downstream, so getting it right matters.
