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.

Billing & Invoicing
Fast billing with barcode support, loose/weight-based items, and invoices with GST, VAT, or sales-tax handling — including GSTR-1, HSN Summary, and GSTR-3B Preview reports. Credit notes, returns and exchanges are built in, and a saved bill can be edited or revised.
Inventory Management
Real-time stock tracking, supplier management, and stock adjustments — built for the way each of the 50 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.
Ledger & Books
A real Chart of Accounts, journal entries, bank reconciliation, and fixed-asset tracking — automatically kept in sync with every sale, purchase, and payment. For your own records — not a substitute for your CA.
Sales & Purchase Orders
Quotations, sales orders, and purchase orders as real commitments before they're billed — convert to invoice with one click when the sale is confirmed. Preview a quotation exactly as it prints and edit it until it is accepted.
Warranty Tracking
Set a warranty on any product and every sale prints “Warranty until…” under the item. Search by phone, customer, bill, product, or serial number, see what ends in the next 30 days, send a WhatsApp reminder, and keep a claim log of what was repaired, replaced, or refunded.
Know Who Changed What
Every login, sale, cancellation, payment, stock change, and setting change is recorded with who did it and when. A one-click integrity check shows your history has not been altered — a quiet safeguard when more than one person uses the software.
Bank & Cash You Can Trust
Every payment and expense moves the right bank or cash balance, so you always know what is actually in each account. Upload a bank statement (PDF, Excel, or CSV) and Sarang matches it against your books, line by line, entirely on your own computer.
Expiry, Batch & Serial Tracking
Sell medicines and other dated goods oldest-first with expiry alerts, and track electronics by serial or IMEI number with the warranty on each unit — built for pharmacies, mobile and electronics shops, and anyone who needs to know exactly which item went to whom.
Offers, Loyalty & Special Prices
Run “buy 2 get 1 free” and quantity-discount offers that apply at checkout, give regular customers a loyalty punch card, and keep special price lists for wholesale or favourite customers — all without a calculator.
WhatsApp & Email Sharing
Share any bill or report to WhatsApp or email — Sarang saves the PDF, opens its folder, and pre-fills the message; you attach the file and press send. Nothing goes out without you.
Doctor Pad
A tablet on the clinic's own Wi-Fi lets a doctor hand-write a diagnosis or prescription instead of typing — the note prints and attaches straight to the patient's record. Available for GP, Specialist, Dental, Vet, and Physio clinics.
Owner View — Check In From Your Phone
See today's sales, outstanding, inventory value, and core reports from your own phone over your shop Wi-Fi — read-only by design, so nothing can be changed or billed by mistake.
HR: Staff, Attendance & Payroll
Track employees, attendance, and leave, then run payroll straight from the same records — one system instead of stitching together separate HR software.
Roles & Permissions
Give a cashier billing access without letting them see profit margins, or an accountant full financial access without letting them touch inventory — every action in Sarang is permission-gated.
Multi-User — More Than One PC At Once
A cashier billing at the counter, you checking today's reports from the back office, both live on the same real data at the same time — over your own Wi-Fi, no cloud, no separate accounts to manage. Starts with 1 PC; add more any time for ₹2,999/$59 per extra PC per year.
Bring Your Existing Data In
Already tracking products, customers, or opening balances in Excel or another system? A guided import wizard brings them in in bulk — no manual re-entry, no lost history.
Phone & Tablet Tools On Your Own Wi-Fi
Diners scan a QR code to order at the table, kitchen staff see live tickets on a phone, field reps capture orders on the road, and patients check themselves into the queue — all offline, all on your own network.

Frequently Asked Questions

Common questions about Sarang

What is Sarang Business OS Lite?

Sarang is a free, fully offline business management app for Windows built by AszureX. It covers billing, inventory, CRM, HR/payroll, ledger and books, and reporting in one installer, with a setup wizard that configures itself for your specific business type — retail, restaurant, clinic, distributor, and 46 others.

Is Sarang really free?

Yes — Sarang is free to use with full functionality for your first 100 days, not a limited trial. After that, keeping it running costs ₹6,999/year in India or $149/year internationally, billed once a year per device. There are no other fees, no forced ads, and no paywalled features during or after the free period.

Does Sarang work without an internet connection?

Yes. Sarang is fully offline by design — billing, inventory, reports, and even its built-in AI assistant all run entirely on your computer with no internet connection required. This is different from most billing and ERP software, which depends on a live cloud connection to function.

What kind of businesses can use Sarang?

Sarang supports 50 business types out of the box, including restaurants and cafés, retail and general stores, pharmacies, distributors, clothing and footwear stores, hardware stores, jewellery shops, hotels, manufacturers, clinics and other healthcare practices, and a range of professional and service businesses. You pick your business type during setup and Sarang configures the right fields, workflows, and reports automatically.

Is my business data safe with Sarang?

Your business data stays on your own device — Sarang stores everything in a local database and AszureX has no access to it. There's no cloud sync and no server your data passes through. Sarang does send a small anonymous usage signal (aggregate, not tied to your business data) — full details are in the Privacy Policy.

How is Sarang different from cloud-based billing or ERP software?

The core difference is that Sarang runs entirely offline on your own device instead of depending on a live internet connection and a vendor's cloud servers. That means no monthly cloud subscription, no downtime if your internet goes out, and your data never leaves your computer. Sarang is priced as one small annual license per device rather than a recurring per-user cloud subscription.

What languages does Sarang support?

13 languages, switchable any time from Settings with no reinstall: English, Hindi, Marathi, Gujarati, Kannada, Tamil, Telugu, Malayalam, Spanish, French, Portuguese, Indonesian, and Arabic (right-to-left supported). Some specialised service-vertical templates run English-only; every retail and product-based business gets the full language set.

What is Sarang's built-in AI assistant?

Sarang ships with a local AI model that runs entirely on your computer, with no internet connection and no data sent anywhere. You can 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. It's currently available in English and runs CPU-only, with no dedicated graphics card required.

What are the system requirements for Sarang?

Sarang runs on Windows 10 or 11 (64-bit) and works comfortably on modest hardware. 8GB of RAM is recommended if you plan to use the on-device AI assistant.

Can I get a refund on a Sarang license?

License payments are non-refundable. Full details are in the Refund & Cancellation Policy.

How do I get started with Sarang?

Download the installer from this page — it's a single installer with no sign-up required beyond your download details, and full functionality is available from day one. See the Download section above for the direct link.

Who makes Sarang?

Sarang is built by AszureX, a software development and technical support company. Sarang is AszureX's own free product, built with the same engineering standards the company applies to client work.
