What do you want to do?
Buy a licence and activate it
After the fifteen days, nothing is deleted and nothing is locked away. Everything you entered stays readable, printable and exportable — you simply cannot enter anything new until a licence code is put in. Activation is offline; no internet is needed for any part of it.
Where to click
- Open Settings › Licence. It shows this computer’s installation code.
- Send us the code — on the order form, or by WhatsApp to +91 85532 01741 — and say which edition you want. We confirm the price with you.
- Pay by UPI or bank transfer.
- We send back a licence code. Paste it into the same screen. Activated.
Good to know
- The licence is perpetual: you buy it once and it keeps working. No renewal, no per-bill charge, no fee for a second user.
- It is tied to the computer it was activated on. If you change machines, send us the installation code the new machine shows and we send back a fresh code — free.
- inbilling.in appears in small type at the foot of bills on the trial and for thirty days after activation; after that, Settings › Licence has a box to turn it off.
