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. Only issuing pauses. The count resets on 1 April with the new financial year, and Pro will lift the ceiling entirely.

No. It is free for as long as you want it, with no card and no expiry date. The only ceiling is 50 issued documents in a financial year.

It is still being built and the price will be announced before it goes live. Nothing that is free today is moving behind it — Pro adds unlimited documents, more than one business, and staff accounts.

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.
