________________________________________
What “free of charge” usually implies (and what it doesn’t)
“Cost-free” equipment commonly give Main invoicing, confined shoppers/objects, or regular monthly invoice caps. Significant GST options —e-invoicing( IRN/ QR),e-way charges, GSTR exports, stoner areas, backups often sit before paid out categories. That’s forfeiture if you know the bounds and when to improve( e.g., as you hite-invoice thresholds or will need inspection trails).
________________________________________
The non-negotiables for GST compliance (even within a free system)
one. E-invoicing readiness (IRN + QR)
Should you cross the e-invoicing turnover threshold, your software have to deliver schema-valid JSON, hit the IRP, and print the signed QR on invoices. (IRP Fundamental principles: IRN + signed QR returned publish-validation.)

2. Dynamic B2C QR (for incredibly large firms)
Only demanded In case your mixture turnover > ₹five hundred crore—MSMEs don’t will need this unless they develop previous the limit. Don’t purchase a attribute you don’t will need nonetheless.

three. E-way Monthly bill
For goods actions (usually > ₹50,000), you’ll need EWB generation and validity controls. A totally free Instrument must at the least export proper knowledge whether or not API integration is paid out.
