The invoice writes itself.
And it is correct.

Type the line items. HISAAB picks CGST and SGST or IGST from the buyer's state, rounds the way the rules say, writes the amount in words, and puts the HSN in the right column. Try it below with a real invoice; nothing is saved.

Type on the left.
Watch the right.

Change the buyer's state and the tax columns switch between CGST/SGST and IGST as they should. Change a slab and everything recalculates. This is the actual arithmetic, not a picture of an invoice.

Signature two: the dashboard

Who owes you,
and for how long.

Most small businesses do not have a cash-flow problem, they have a collections problem. The ageing bars are the first screen you see when you log in, and the overdue list has a chase button next to every name.

Anything past 60 days needs a phone call, not another email. The list below is sorted by how long it has been sitting.

Signature three: GST returns

GSTR-1, built
from your invoices.

You already typed the invoices. Typing them again into a return form is somebody's bad idea. This table is generated, checked against your books, and exports in the portal's own JSON format.

Pricing

Per business.
Not per user.

Your accountant, your partner and your staff all get logins on every plan. Charging per seat for a five-person firm is how software gets used by one person and resented by four.

Everything exports to Excel and to Tally-compatible XML, on every plan including the free one, with one button and no support ticket. Data sits in Mumbai, encrypted at rest, backed up daily with a 30-day window. We have never sold or shared customer data and there is no line in our revenue where that could hide.

FAQ

Business owner
questions.

Yes, from the place of supply against your own registered state. Same state gives CGST and SGST at half the slab each; different state gives IGST at the full slab. Union territories without a legislature use UTGST, which we handle too. This single rule is where most spreadsheet invoices go wrong.

Yes, with their own login on every paid plan, and a CA can hold multiple client accounts under one dashboard for free. About 900 CAs use HISAAB purely on the client side.

Invoicing does. The app keeps working offline, queues everything, and syncs when the connection returns. E-way bills and portal exports need a connection, since they talk to a government server.

Included on Business and Books for turnover above the e-invoicing threshold. We generate the IRN and QR code through a registered IRP and print them on the invoice automatically. Below the threshold it stays off so your invoices are not cluttered.

Three templates, your logo, your colour, your terms and your bank details, plus a UPI QR if you want one. Beyond that we do not build a page designer, because every invoice still has to satisfy Rule 46 and freedom there causes more problems than it solves.

Twenty-five invoices a month, forever, with the full tax logic and unlimited users. No card, no trial clock. About a third of our accounts have never paid us anything and that is fine; they tell other people about us.
