What's Inside

Everything a growing business needs to run day to day

One installer, one local database, every core operation covered — no separate tools to stitch together.

Inventory Management
Real-time stock tracking, supplier management, and stock adjustments — built for the way each of the 43 supported business types actually operates.
Customers & Suppliers
Track customer relationships, outstanding payments, credit limits, and supplier accounts in one place — no separate CRM needed.
Reports & Analytics
Sales, inventory, and financial reports with a tax engine that covers GST as well as generalised tax and currency handling for use outside India.
Ask Your Business
An on-device AI assistant that answers questions about your own sales, inventory, and customers — fully offline, nothing ever leaves your computer.
Backup & Restore
One-click local backups with integrity verification before every restore — your records stay safe and entirely under your control.

On-Device AI

"Ask Your Business."

Sarang ships with a local AI model that runs entirely on your computer — no internet required, ever. Ask it about today's sales, low stock, or outstanding payments in plain language, and it answers from your real data using a fixed set of verified queries. It never invents numbers, and it never sends your data anywhere.

Currently available in English. CPU-only — no dedicated graphics card required.
