Notebooks and Excel were never built to run a factory
If any of this sounds like your week, you already know the cost. Grevity fixes it on day one.

Local first
Built in Rajkot, for Rajkot
Grevity did not start in a boardroom. It started with casting units, forging shops, engineering works, auto-parts traders and textile businesses around Rajkot telling us the same thing: the software available was either too heavy, too costly, or built for somebody else’s business.
So we built for how work actually happens here — job-work realities, BOM-based production, party ledgers, and support in Gujarati on the phone when you need it. Rajkot first, then all of Gujarat, then India.
- Support in Gujarati, Hindi and English
- On-site setup and training in Rajkot
- Built around casting, forging and engineering workflows
- Priced for small and medium businesses, not enterprises

Questions we get every week
Is my business data safe?
Safer than most software, because nothing ever leaves your premises. Your entire database sits on your own USB pendrive — it is never uploaded to any server and we cannot see it. Access is protected by secure login and role-based control, every change is recorded in audit logs, and one-click backup and restore let you keep copies wherever you want them.
Do I need internet to use it?
Never. Grevity is offline software only — it runs from the USB pendrive with its own local database on any Windows computer. No connection, no server, no login to a website. Power cuts and network problems on the shop floor stop being your problem.
Are the invoices tax compliant?
Grevity generates tax invoices with HSN codes, correct tax breakups, your own invoice prefix and financial-year-wise numbering, exported as clean PDFs. Your reports and Excel exports are formatted so your CA can work with them directly.
Can I run more than one firm?
Yes. Multi-company management lets you switch between businesses from one login, each with its own products, parties, invoice numbering, capital accounts and reports.
Do you support Gujarati and Hindi?
Our team supports you in Gujarati, Hindi and English on phone and WhatsApp, and this website is fully available in Gujarati. Ask about interface language options during your demo.
I already have data in Excel or Tally. Can I move it?
Yes. We help you import your item master, HSN codes, customers, suppliers and opening balances during setup, so you start with your real numbers instead of a blank screen.
How long does setup take?
Most Rajkot businesses raise their first invoice on the same day. If your item list is large, we finish the import within two working days — with on-site help wherever we can reach.
Is there an AMC or hidden charge?
Nothing hidden. Grevity is ₹7,000 for the first year — pendrive, setup, data import, training and support included — and ₹5,000 a year after that. That yearly renewal is the only recurring charge and it covers your licence, all updates and support. No monthly fee, no per-invoice charge, no separate AMC on top. Tax applies as per law.
