________________________________________
What “totally free” normally usually means (and what it doesn’t)
“Free of charge” instruments ordinarily provide core invoicing, minimal prospects/products, or regular monthly Bill caps.

three. E-way bill
For merchandise actions (typically > ₹50,000), you’ll will need EWB era and validity controls. A totally free Software really should at the least export right data regardless of whether API integration is paid out.

four. GSTR-Prepared exports
Clean GSTR-1/3B Excel/JSON exports reduce glitches—essential because 2025 improvements are tightening edits in GSTR-3B and pushing corrections upstream by way of GSTR-1A.
