How to judge "cheapest" invoicing software
"Cheapest" depends on hidden costs: per-user fees, turnover caps on free tiers, per-device licenses, and add-ons for GST/e-invoicing. A tool that's free but caps users or turnover can cost more than a flat plan once you grow. Compare total cost for your team size, not just the headline price.

Prices as of June 2026; verify current. All prices exclude 18% GST. Nidhi Books: from ₹399/month (first app, unlimited users; +₹99/mo per add-on).
The honest take: if you qualify, free Zoho Books or free Vyapar mobile are cheaper than anything. Once you exceed their caps or need unlimited users on a flat fee, Nidhi Books from ₹399/month is the cheapest full GST invoicing option. We'd rather you start free if you qualify than overpay.
