2. Dynamic B2C QR (for really massive enterprises)
Only needed If the combination turnover > ₹five hundred crore—MSMEs don’t have to have this unless they increase earlier the Restrict. Don’t purchase a aspect you don’t have to have however.
3. E-way Monthly bill
For merchandise actions (generally > ₹fifty,000), you’ll will need EWB technology and validity controls. A no cost tool ought to no less than export suitable data regardless of whether API integration is paid out.
4. GSTR-ready exports
Clean GSTR-one/3B Excel/JSON exports decrease errors—vital since 2025 adjustments are tightening edits in GSTR-3B and pushing corrections upstream by way of GSTR-1A.
