This guide distills what “cost-free” truly addresses, which features you need to have for GST, and how To guage freemium applications without having jeopardizing penalties or rework. It follows E-E-A-T principles—very clear, present-day, and source-backed.

What “cost-free” usually implies (and what it doesn’t)
“Absolutely free” tools normally present Main invoicing, limited buyers/goods, or month to month invoice caps. Important GST options —e-invoicing( IRN/ QR),e-way expenses, GSTR exports, stoner areas, backups commonly sit right before paid categories. That’s forfeiture if you realize the boundaries and when to update( e.g., when you finally hite-Bill thresholds or will need inspection trails).

The non-negotiables for GST compliance (even inside of a free plan)
1. E-invoicing readiness (IRN + QR)
If you cross the e-invoicing turnover threshold, your software program need to create schema-valid JSON, hit the IRP, and print the signed QR on invoices. (IRP basics: IRN + signed QR returned publish-validation.)
two. Dynamic B2C QR (for pretty significant enterprises)
Only demanded In the event your combination turnover > ₹500 crore—MSMEs don’t want this Unless of course they develop earlier the Restrict. Don’t purchase a function you don’t need nonetheless.
three. E-way bill
For goods actions (normally > ₹50,000), you’ll have to have EWB era and validity controls. A free of charge Instrument should not less than export proper info even when API integration is compensated.
4. GSTR-Completely ready exports
Clear GSTR-one/3B Excel/JSON exports lower mistakes—critical mainly because 2025 adjustments are tightening edits in GSTR-3B and pushing corrections upstream by using GSTR-1A.
5. Time-Restrict alerts for e-invoices
For taxpayers with AATO ≥ ₹10 crore, reporting to IRP is capped at thirty times from 1 April 2025; your Software must alert you before the window closes.
