The entry plan is ₹399/month and includes GST billing, accounting and inventory with unlimited users — there are no per-user or per-seat charges. Additional modules cost ₹99 each, so you only pay for what you add. Most small businesses pay far less than per-seat tools once their team grows.

Answers: GST, accounting & billing software questions for Indian businesses
