Do I need a GSTIN to use HSR Billbook?

No. You can run the whole product — billing, stock, purchases, reports — without one, and add a GSTIN later from your business settings. A GSTIN is only required for the compliance features that genuinely need one, such as e-invoicing.

What happens after the 7-day free trial?

Nothing is deleted and nothing is locked. The trial starts the moment you create your business, no card required. When it lapses you get a reminder on your dashboard and a prompt to pick a plan — your data stays exactly where it is.

Can I run more than one business from one login?

Yes. Each business keeps its own GSTIN, numbering series, branding, team and books, and each can have as many branches as you need. You switch between them from the top bar without signing out.

Will my invoice numbers stay sequential?

Yes, and this is enforced rather than assumed. Every document number is issued by the server inside a database transaction, scoped to the business, branch, series and financial year. Two people billing at the same instant cannot be given the same number, and the series never develops a gap.

Can I edit an invoice after issuing it?

No, by design. An issued tax invoice is frozen. To reverse or reduce one you raise a credit note against it, which is what the GST law expects and what your GSTR-1 reflects. It keeps your books defensible in an audit.

Does it work on a phone?

Yes. The app is fully responsive and installs to your home screen as a progressive web app, with a bottom bar for the things you do most — dashboard, POS, invoices, purchase bills and parties.

What happens if the internet drops mid-bill?

Data you have already loaded stays readable, because the app keeps a local cache on the device and reconnects on its own. Issuing a new invoice does need a connection, since the number and the tax have to be settled by the server.

Can I control what my staff can see?

Yes. Four ready-made roles cover most teams — owner, manager, accountant and cashier — and you can build your own across eleven modules with separate view, create, edit and delete switches. Permissions are checked on the server, so a restricted user cannot get past them.

Why teams switch

Four things that break every month, and what replaces them

Most businesses do not lose time to billing. They lose it to fixing billing afterwards.

Your GSTR-1 is rebuilt by hand every month from an Excel file nobody trusts.

Registers build themselves as you bill. Export the workbook, or the portal JSON, for any period — in seconds, not an evening.

Invoice numbers skip, repeat, or get edited after they have gone out.

Numbers come from the server inside a transaction, per branch and financial year, and the document freezes the moment it is issued.

Stock on the system stopped matching stock on the shelf months ago.

Every sale and receipt writes a ledger entry against the document that caused it, so any discrepancy has a paper trail you can walk back.

Nobody can say exactly how much is owed to you right now.

Receivables and payables per party, oldest first, with the unpaid documents behind each balance — netted into one number.

One app, four jobs

Deep enough for your accountant, quick enough for the counter

Each area below is a full module, not a checkbox on a feature list.

Every document you bill with, in one place

Tax invoices, counter sales, quotations, credit notes and delivery challans — all numbered, taxed and locked by the server, not by whoever is at the keyboard.

Gap-free invoice numbers per branch, per financial year
GST split calculated server-side — CGST/SGST or IGST, automatically
Invoices freeze the moment they are issued
Five print themes across seven page sizes

Tax invoices that pass a Rule 46 check

Place of supply, reverse charge, consignee, PO reference, LUT, shipping bill — every particular the CGST Rules ask for has a field, and the PDF prints it where an officer expects to see it.

A POS counter that keeps up

Search, scan, add, take cash or UPI and print — without leaving the keyboard. Counter sales land in the same books as everything else, tagged so you can still tell them apart.

Quotations that become invoices

Send a quote, track whether it was accepted, then convert it to a tax invoice in one click. The original stays linked to the invoice it produced.

Recurring invoices that run themselves

Set a schedule — daily through yearly, every N periods, with an end date or a cap. A scheduler raises each invoice on time, with real numbering and real stock movement.

Credit notes tied to the original

Raise a credit note against a specific invoice for a return, a post-sale discount or a service shortfall. It carries into GSTR-1 as CDNR or CDNUR on its own.

Delivery challans for non-supply movement

Job work, approval sales, samples, exhibitions. Vehicle and transporter captured, value recorded for reference — without treating the movement as a taxable supply.

Built to be audited

The boring guarantees that matter three years later

Billing software earns its keep the day someone asks you to prove a number. These are the design decisions that make that day uneventful.

Documents cannot be quietly edited

An invoice freezes the instant it is issued. Changing what a customer already received means raising a credit note — the same trail an assessing officer would expect to find.

Permissions hold on the server

Hiding a button is not access control. Every action is re-checked server-side against the role, so a restricted user cannot reach a screen or an API they should not.

Your GSP credentials stay sealed

IRP credentials are write-only from the app and are never readable by any browser, including yours. Submissions are signed server-side under your own GSP account.

Numbers are issued once, in order

Document numbering runs through a database transaction scoped to the branch, series and financial year — so two tills billing at once can never be handed the same number.

Card details never touch us

Subscription payments run through Razorpay. Every payment is verified by signature on our side and reconciled by webhook, so a dropped connection cannot lose your renewal.

A weak connection is not a dead shop

The app caches on the device and reconnects on its own, so browsing your books keeps working through a patchy line rather than showing an error page.
