When a shop gets busy
- On Pay-as-you-bill: when your shop makes more than 20,000 bills in a calendar month, it moves to the Busy plan automatically. For that month you pay ₹1,099 in total: the fees you already paid that month are taken off.
- On the Annual plan: it moves to the Busy annual plan for the rest of your year. You pay the difference for the months left: (₹12,000 − ₹6,200) × months left ÷ 12. With 6 months left, that is ₹2,900.
- Billing never stops at the moment of the move. You get 7 days to recharge any amount due.
- When a year ends, the shop goes back to monthly billing: Pay-as-you-bill, or the Busy plan if it is still busy. You can buy another year any time.
Prices are in Indian rupees, plus applicable taxes. A cancelled bill gets its ₹1 back. Fees are taken from your prepaid service balance, which you top up by UPI to inaivu IT.
FAQ
Questions shopkeepers ask.
Do I need a computer?
No. KanakkuPaar runs in the browser on any Android phone or tablet. You can add it to your home screen like an app.
What happens if the internet goes off?
You can keep billing. Bills are saved on the phone and sent automatically when the connection returns.
How do I pay the fees?
You keep a prepaid service balance. Recharge by UPI to inaivu IT and enter the reference in the app; we confirm it, usually the same day. The ₹99 monthly fee and ₹1 bill fees are taken from that balance.
Is there a free trial?
Yes. Your first 30 days are completely free: no monthly fee, no bill fees and unlimited bills. Before the trial ends you choose a plan; nothing is charged until you do.
What if I make a lot of bills?
Bill fees stop at ₹500 in a calendar month, so up to 20,000 bills the most you pay is ₹599 a month plus taxes. Above 20,000 bills in a month, your shop moves to the Busy plan automatically: ₹1,099 a month or ₹12,000 a year, unlimited bills.
Can I pay for a year at once?
Yes. The Annual plan is ₹6,200 for 12 months with no monthly or bill fees, instead of ₹7,188 (12 × ₹599): you save ₹988. The Busy plan is ₹12,000 a year instead of ₹13,188, saving ₹1,188. If your shop goes above 20,000 bills in a month during that year, it moves to the Busy annual plan and you pay only the difference for the months left.
Can my counter staff bill without seeing my accounts?
Yes. Add a biller with their own login (email or mobile number). Billers can make bills, manage products and close the cash drawer by counting the cash blind. Reports, the credit book, your balance and settings stay with you, the owner.
Does KanakkuPaar take a cut of my UPI payments?
No. Customers pay your own UPI ID. We never touch that money and charge no percentage.
Can I use it on more than one phone?
Yes. Sign in with the same account on another phone or tablet. Bills from both are kept together, and cancelled bills and price changes are recorded.
Can I stop any time?
Yes. There is no contract and no auto-debit. If you stop recharging, nothing more is charged.
