Important Update: E-Invoicing & The Strict 30-Day Reporting Rule

The government has tightened E-Invoicing regulations. If your turnover exceeds ₹5 Crore, e-invoicing is mandatory, and businesses over ₹10 Crore now face strict 30-day reporting deadlines.

The ₹5 Crore Mandate

Staying compliant is getting stricter. Since August 1, 2023, generating Invoice Reference Numbers (IRNs) for B2B and B2G transactions is legally mandatory for any business with an Aggregate Annual Turnover (AATO) of ₹5 Crore or more in any financial year since 2017-18.

Pro Tip:

Waves ERP eliminates the stress of 30-day deadlines. Just click 'Save' on your bill, and the software automatically communicates with the portal to generate your IRN and QR code in milliseconds.

The New 30-Day Deadline

Additionally, a massive change regarding time limits is now actively enforced. As of April 1, 2025, firms with an annual turnover of ₹10 Crore or more must report their invoices to the government portal within 30 days of the invoice date. You can no longer hold onto invoices; missing this window blocks the portal upload and risks heavy penalties.

Key Takeaways

  • Verify your Aggregate Annual Turnover (AATO) to see if these rules apply to you.
  • Stop manual uploads: ensure you are not holding onto B2B invoices past the 30-day limit.
  • Enable automated E-Invoicing directly inside your Waves ERP settings to avoid blocked IRNs.
