Straight answers.

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.

Yes, on one account. Sign up on either, then open app.bahisathi.com in any browser and the same business is there. Most people bill from the phone at the counter and do month-end work on a laptop.

Not yet. In the meantime the web app runs in any modern mobile browser, including Safari, on the same account and the same data.

There is no bulk import yet, so customers and price-list items are added as you first bill them. After that they are saved and you pick them from a list.

It compares your state against the place of supply on the document. Same state means the tax splits evenly into CGST and SGST; different states mean the whole amount is IGST. Within a union territory the SGST half is UTGST instead.

The tax invoice carries the fields Rule 46 lists: both GSTINs, a serial number within the 16-character limit, the date, HSN or SAC per line, taxable value, the rate and amount of each tax head, place of supply, the total in words and a signature block.

The series restarts at 1 for the new financial year, which is what the rules require, and the old year’s documents keep their numbers. Each document type has its own series.

Not directly. You export the month as GSTR-1 JSON and upload it to the government offline utility, or export CSV for your accountant. The export covers B2B, B2CL, B2CS, credit and debit notes, the HSN summary and the document series. Check the figures against your books before you file.

Not yet, though both are planned. If your turnover already crosses the e-invoice threshold, BahiSathi is not the right tool for those invoices today.

Drafting carries on exactly as before, so you will not lose work, and nothing already issued is touched. Only issuing pauses, and the count resets on the 1st of the next month. If you are hitting it every month, that is the point at which a paid plan is worth it.

No. It is free for as long as you want it, with no card and no expiry date. The only ceiling is 20 issued documents in a calendar month, and it refills on the 1st. Plenty of people will never need more than that, and that is fine by us.

Pro is ₹1,499 a year for unlimited documents, up to 3 businesses and staff logins. Practice is ₹4,999 a year for CAs and consultants, covering up to 25 client businesses with one combined GSTR-1 export. Both are inclusive of all taxes and are a single payment for 12 months — no autopay, no mandate on your card, nothing that renews itself. When the year is up you decide whether to pay again.

The first 100 customers can pay ₹999 once and keep Pro for good — no annual renewal, ever, including the features we add later. It is capped at 100 and will not reopen once those are taken. It exists to fund the next six months of work and to find the early customers who will tell us honestly what to build.

Because it does less, on purpose. BahiSathi makes GST documents and does that part properly; it is not accounting software with ledgers, inventory and payroll. Comparable mobile-plus-desktop billing software in India runs around ₹4,000 a year. If you need full accounting, buy that instead — we will not pretend to replace it.

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.

Drafting, editing, browsing and previewing all work offline on Android, and your changes sync when you are back on a network. The one thing that needs a connection is issuing, because the serial number has to be reserved centrally so that no two devices can produce the same one.

Yes, from Settings in the Android app, or by writing to us from your registered email address. Export your issued documents first — GST law expects you to keep them, and deletion is permanent.
