Hindi where it matters, English where it helps
The interface, the invoice and the customer messages are all available in Hindi. Some things stay in English on purpose — GSTIN, HSN codes and the tax labels on the invoice, because that is what the GST format expects and what your CA and your buyers are reading. The result is a bill that a customer understands at a glance and an accountant can file from without translation. You can switch the interface language per user, so a Hindi-reading counter assistant and an English-reading accountant use the same account comfortably.
Why this decides whether software survives in a shop
The owner usually manages either way. The staff member does not. Put a screen full of English labels in front of someone who has kept a register for fifteen years and within a week the register comes back out and the software becomes a thing that gets updated on Sundays, badly. In Hindi the same person is billing unaided after one session, which is the difference between software that is used and software that was bought.
Support in Hindi, from people who know the trade
When you call, someone answers in Hindi and they know what a challan is, why cement and steel sit at different GST rates, and what a contractor ledger looks like. That is not a small thing — most support desks are reading from a script written for a generic retail product. Phone and WhatsApp support run Monday to Saturday, and a screenshot on WhatsApp usually settles a problem in one reply.
What Hindi support means in practice
It means the person on the phone understands the question before you have finished explaining it. A support desk reading a script for a generic retail product does not know why cement and steel sit at different GST rates on the same bill, what a site challan is for, or why a shop needs to bill in kilos while buying in tons. Ours does, because the software was built in a hardware market in Patna for shops exactly like yours. Send a screenshot on WhatsApp with your registered number and most problems come back solved in the first reply rather than after three exchanges.
