What is CaratOS?
CaratOS is a complete jewellery ERP software built for Indian jewellers. Also known as CaratOS ERP, it brings billing, inventory, GST, accounting, CRM, orders, karigar job work, gold saving schemes and Girvi (gold loan) into one offline, secure system — so a jewellery business runs on one set of books instead of a billing app, a stock register and a separate accounting package.

People search for the product in different ways — CaratOS, Carat OS, CaratOS ERP, CaratOS software and caratoserp. All of these mean the same jewellery software made by ScalarThink. The name comes from the carat — the unit jewellers use for gold purity and gemstone weight — and OS, because it is meant to be the operating system for the whole jewellery business.
Who makes CaratOS
CaratOS is designed and built by ScalarThink Innovations Pvt. Ltd., a software company based in Dhanera, Banaskantha, Gujarat, India. ScalarThink builds CaratOS in-house, which is why the product follows the way Indian jewellers actually work — weights and purity on every piece, daily metal rates, old gold across the counter, karigars holding your metal and, for many shops, a Girvi book alongside retail.
