Trying to find absolutely free GST billing software package that’s truly compliant and dependable? This guideline distills what “cost-free” really addresses, which features you have to have for GST, and how to evaluate freemium instruments with out jeopardizing penalties or rework.

What “free of charge” commonly means (and what it doesn’t)
“Cost-free” applications usually offer you Main invoicing, confined clients/things, or every month invoice caps.

That’s forfeiture if you already know the bounds and when to enhance( e.g., once you hite-Bill thresholds or need inspection trails).
________________________________________
The non-negotiables for GST compliance (even in a totally free strategy)
1. E-invoicing readiness (IRN + QR)
In the event you cross the e-invoicing turnover threshold, your computer software need to create schema-valid JSON, hit the IRP, and print the signed QR on invoices. (IRP basics: IRN + signed QR returned post-validation.)

two. Dynamic B2C QR (for incredibly substantial corporations)
Only essential When your mixture turnover > ₹500 crore—MSMEs don’t need this Except they improve previous the limit. Don’t buy a attribute you don’t want however.

three. E-way Invoice
For items actions (commonly > ₹50,000), you’ll need EWB technology and validity controls. A cost-free Instrument should no less than export proper information even if API integration is paid out.

4. GSTR-All set exports
Thoroughly clean GSTR-one/3B Excel/JSON exports minimize faults—crucial simply because 2025 variations are tightening edits in GSTR-3B and pushing corrections upstream through GSTR-1A.

five. Time-limit alerts for e-invoices
For taxpayers with AATO ≥ ₹ten crore, reporting to IRP is capped at 30 days from one April 2025; your Instrument should really warn you prior to the window closes.
