CaratOS
The modern operating system for smart jewellery businesses
What is CaratOS?
CaratOS is desktop software for running a jewellery business — billing, stock, Girvi, accounts, GST, orders, karigar work, saving schemes, reports & analytics — developed by ScalarThink Innovations PVT LTD.
It is built for the way a jewellery shop actually works. You record what happened at the counter; the software keeps the stock, the books and the GST straight behind it, so the owner sees the real picture every evening instead of at month-end.
It runs entirely on your own computer, is set up and taught by our team, and is used today by single-counter shops, large showrooms, wholesalers and Girvi businesses. The name says what we care about: Carat, for purity and precision, and OS, for the foundation a business runs on.

Our Story
How CaratOS came to be
We kept meeting the same situation: a business dealing in high value every day, run on a rough register and memory. Fine calculated by hand and repeated wrong on every bill. Stock that never tallied. Pledges in one program, sales in another, and cash that reconciled in neither. And software from another era that staff avoided because going back one screen was a struggle.
CaratOS was built to remove that — to give a jeweller one place where every gram and every rupee is accounted for, without needing an accountant to read it. We have kept the focus narrow on purpose: software that understands jewellery, and nothing else.
