Features
Only what you need to bill correctly.
Every screen exists to get one document out of the door faster. That's the whole test for whether a feature ships.
Gets the tax split right
Supplier state same as the place of supply? CGST and SGST. Different state? IGST. Union territories get UTGST. You pick the place of supply and the arithmetic follows.
Quote today, invoice tomorrow
Send a quotation, win the job, then turn it into a numbered tax invoice without retyping a single line.
PDFs you can send with pride
Your logo, every field Rule 46 asks for, HSN or SAC per line, the amount in words and a signature block. Share on WhatsApp, email it, or save it.
Keeps working without signal
Draft, edit and preview offline on Android, even in a basement godown. Only issuing a numbered document needs the network.
Phone and laptop, one account
Start the quotation on Android at the customer's shop, finish it in the browser back at the office. Same account, same data.
Ready for filing
Export a month as GSTR-1 JSON for the offline utility, or a flat CSV for your accountant. B2B, B2CL, B2CS, CDNR, CDNUR, HSN and DOCS.
Also inside: credit and debit notes under Section 34, GSTIN checksum validation, reverse charge, discounts and cess per line, invoice serials that restart every financial year, and staff accounts with roles.
How it works
Three steps, then it's out of your hands.
- 1
Set up your business once
Name, address, logo, and a GSTIN if you have one. Two minutes, and every document after that carries your letterhead.
- 2
Build the document
Pick a customer, pull items from your saved price list, set quantities. Totals and tax move as you type.
- 3
Issue and send
One tap assigns the legal serial number and renders the PDF. WhatsApp it on the spot.
On your phone
Big buttons, few screens, everything one tap away.
The Android app is built to stay quick on an entry-level phone, because that's what most of our users carry.

Reaching the free ceiling only blocks issuing. Your drafts stay untouched, and the count resets on 1 April.
Do I need a GSTIN to use BahiSathi?
No. Leave the GSTIN blank while setting up your business and you can raise quotations and bills without one. Add it later in Settings and the tax columns appear on your documents.
Where is my data kept?
On servers in the Mumbai region, encrypted in transit. Only you and the people you invite to your business can see it. The privacy policy has the full detail.
What happens when I reach 50 documents?
Drafting carries on exactly as before, so you won't lose work. Only issuing pauses. The count resets on 1 April with the new financial year, and Pro will lift the ceiling entirely.
Is there an iPhone app?
Not yet. In the meantime the web app runs in any modern mobile browser, on the same account and the same data.
Do you support e-invoice (IRN) and e-way bills?
Not yet, but both are planned. If your turnover already crosses the e-invoice threshold, BahiSathi isn't the right tool for those invoices today.
Your next invoice is a minute away.
