CaratOS vs Jwelly ERP: a side-by-side for jewellers

The two in one look

Jwelly ERP is jewellery software from MMI Softwares Pvt. Ltd. in Mathura, Uttar Pradesh. Its website describes versions for retail jewellers, wholesalers, manufacturers, multi-branch owners and money lenders. CaratOS is jewellery billing and shop management software made by Izara Gems Pvt. Ltd. in Delhi, for retail jewellers who want billing, old gold, stock, GST and dues in one place, in English or Hindi.

Everything about Jwelly below comes from jwelly.com, checked on 2 November 2026. Where their website doesn’t say something, we write “not published on their website” rather than guess. Software changes, so ask them in a demo before you rely on any line here.

Where Jwelly does more

It is only fair to start here, because some shops should stop reading and call Jwelly.

Girvi. Jwelly has a version for money lenders. Their website describes interest worked out on both Hindi and English calendars, KYC with customer documents, receipts with due dates, and moving pledged items between branches. CaratOS has no girvi at all.

RFID. Their retail page talks of RFID-powered tracking and counting stock in minutes with RFID scanners. CaratOS has no RFID; stock checks use barcode or QR tags.

Offline desktop. Their FAQ says Jwelly has a cloud version and a desktop version, and that the desktop version works completely offline on Windows 7 or higher. CaratOS needs a connection today; CaratOS Desktop is coming soon, with no date yet.

Manufacturing. Their manufacturing version covers job cards, metal issued to and received from karigars, weight checks of input against output, wastage and wages. CaratOS has karigar jobs, and production stages on Growth, but no manufacturing bill of materials.

Phone apps and more. Jwelly lists an owner mobile app, and links its Jewel Konnect app on Google Play and the App Store. It also lists weighing scale links, biometric attendance with salaries, and digital gold. CaratOS has no Android app; you use it in the phone’s browser.

Where CaratOS does more

Jwelly also lists GST reports, Tally integration and WhatsApp sharing, and may cover more of what follows; ask in a demo.

A price you can read before you call. CaratOS Starter is ₹1,199 a month and Growth is ₹3,999 a month, or ₹42,999 a year, with GST included. Everything each plan has is written on pricing. Jwelly doesn’t publish a price on its website, so you learn the cost after talking to them.

A trial without a card. Request 15 days of Starter. The trial starts when CaratOS approves it, and no card is needed.

Nothing to install. CaratOS runs in the browser at app.caratos.co.in, on a laptop, tablet or phone. There are no setup files.

Old gold on the same bill. Weigh the customer’s old gold, enter the tested purity, and CaratOS works out the fine weight, values it at your old-gold rate and takes it off what they pay, on every plan. See billing and old gold.

Your CA and Tally. Your CA gets a free read-only login. Reports give GSTR-1 and GSTR-3B figures with the HSN summary. Tally export is on Starter, and Growth adds live sync.

Hindi for each person. Your salesperson can bill in Hindi while you read reports in English, and each person can switch any time.

What CaratOS doesn’t do today

So you don’t find out after paying: CaratOS has no girvi, no RFID, no Android app and no manufacturing bill of materials. It works online only until CaratOS Desktop arrives. Production stages, karigar pay and wastage, approval memo, savings schemes, discount limits and e-invoices are on Growth, not Starter. Starter has one login plus your CA; Growth has five.

Price: what we could and couldn’t check

For CaratOS the sums are simple. Starter at ₹1,199 a month is ₹14,388 over 12 months. Growth at ₹3,999 a month is ₹47,988 over 12 months, or ₹42,999 if you pay for the year. GST is already inside these figures.

For Jwelly we couldn’t find a price on jwelly.com. Their FAQ says they offer AMC packages with updates and support, and to contact them for AMC plans and pricing. Ask them for the full first-year cost and the yearly cost after that, both with GST, for the version and features you need.

Compare like with like. If you need girvi, RFID or manufacturing, CaratOS can’t give you those at any price, so the cheaper line isn’t the useful one. If you don’t, compare the cost for billing, stock, old gold and GST alone. Our price guide explains what jewellery software usually costs in India.

Who each one suits

• Jwelly suits you if girvi is part of your business, or you want RFID scanners for stock.
• Jwelly suits you if your shop’s internet is unreliable and you want a desktop version that works offline today.
• Jwelly suits you if you manufacture, and want job cards and metal issued and received for each karigar in one system.
• CaratOS suits you if you sell from one counter or a few, and want billing, old gold, stock with HUID, GST and dues in one browser app.
• CaratOS suits you if you want to know the full price before a sales call, and try it for 15 days without a card.
• CaratOS suits you if your staff are more comfortable in Hindi and you read reports in English.
• Use both, or neither, honestly. Some shops keep girvi in one tool and the counter in another. If you need manufacturing with a bill of materials, ask Jwelly directly; CaratOS doesn’t do it.

Moving from Jwelly to CaratOS

If you decide to move, this is how it usually goes. CaratOS helps you move on every plan.

Steps to move across

• Take your data out first. Ask Jwelly for an Excel export of your stock, customers and dues. Their website doesn’t say what formats it exports, so ask in writing.
• Keep girvi where it is. CaratOS has no girvi, so leave your gold loan records in Jwelly or your existing register. Don’t close that account until every loan is settled.
• Send us the files. Send us the export or your Excel sheets, and we bring your stock, customers and dues into CaratOS. You check every row before anything is added.
• Set your rates and print tags. Enter the day’s gold and silver rates, then print barcode or QR tags for your pieces, with the HUID carried on each one.
• Run both for a week. Make each bill in CaratOS and check it against your old software, until you trust the totals.
• Give your CA a login. Your CA checks the GST figures and the Tally export before the next return.

Questions to ask both in a demo

• Make a bill for a 22K chain with making charges and an old gold bangle in exchange, and show me every line.
• Does the HUID print on the bill? Hallmarked gold jewellery must carry a 6-character HUID under BIS rules.
• Is GST 3% on the bill, split as CGST and SGST in my state and IGST for a customer from another state?
• What is the full price for the first year and each year after, with GST?
• Does it work without internet, and what happens to bills when the connection comes back?
• Can my CA log in, and how do the figures reach Tally?
• How do I take all my data out in Excel if I leave?

See CaratOS with your own sale

Book a demo and bring a real bill from last week: the pieces, the making, the old gold and how the customer paid. We’ll make that bill in CaratOS in front of you. Or request the 15-day trial and try it at your own counter. To see every comparison in one place, read jewellery software alternatives compared.
