GST E-Invoice in 2026: the MSME 5-minute checklist

GST · 2026-05-21 · 4 min read

If your turnover crossed ₹5 cr in any FY since 2017–18, e-invoicing is mandatory. Skipping it = ₹10,000 per missed invoice or 100% of tax, whichever is higher.

The 5-step checklist

1. Register on the IRP portal (e-invoice1.gst.gov.in). Use your GSTIN and create API credentials.
2. Drop those credentials into your ERP — in WAM ERP, Settings → Integrations → GSTN.
3. Save your first tax invoice. The system fetches the IRN + QR code in 2–3 seconds.
4. Print or share. The IRN-stamped invoice is what your customer needs for ITC.
5. That's it. No more manual portal uploads.

WAM ERP includes the e-invoice + e-way bill workflow on every paid plan. Tally charges extra for it.
