Offline billing software for shops & counters
Bill customers even when the internet is down — fast GST invoices, barcode scanning and thermal receipts on a desktop app that never depends on the cloud.
Live product UI — sample data.
Never stops for the internet
The counter keeps running with zero connectivity — bills, stock and GST all work offline.
Counter-fast
Barcode scan-to-add, keyboard-first entry, and 80mm thermal or A4 printing in one click.
Real books behind it
Every bill posts to a proper ledger and updates stock and GST — not just a paper receipt.
What this actually means in practice
Consider the ways a counter loses its connection on a Saturday evening: the broadband is out, the router has hung, the mobile dongle has run out of data, or the tax portal itself is unwell. A till that needs a server for every bill has nothing to offer at that moment. The queue does not disperse politely; the shop writes on a pad and re-keys later, and the re-keying is precisely where quantities, rates and document numbers go wrong.
The Desktop edition never has that moment, because a bill was never a request in the first place. The document is written to the database on the machine in front of you, its number is issued from the local series, stock decrements, tax is computed and the receipt prints. When the line returns there is nothing to synchronise and nothing to re-enter: the evening’s sales are already in the books, and already in the return.
Be clear about what offline does not cure. A power cut stops the computer and the printer, so a counter that must trade through one needs the till and its printer on a UPS. And an e-invoice IRN or an e-way bill number is issued by the portal, not by us: the document is prepared and waits, then goes up when the connection is back. Everything else at the counter simply carries on.
| What has failed | What the counter can still do |
|---|---|
| Broadband or the router | Bill, scan, print, take payment, move stock — all of it |
| The mobile data pack | Everything; the app was not using it anyway |
| The GST portal | Bill normally; the e-invoice payload is prepared and queued |
| A power cut, no UPS | Nothing until power returns; bills already saved are intact |
| A power cut, till and printer on UPS | Carry on billing and printing as usual |
| Our own servers | Everything; only updates and licence checks wait |

What it does not do
- · This describes the Desktop edition. The Cloud edition is browser-based and needs a working connection by design.
- · Offline does not mean powered. Without a UPS a cut stops the PC and the printer like any other appliance in the shop.
- · IRN and e-way numbers are issued by the portal. Offline you can prepare the document; you cannot obtain the number.
Frequently asked
Will billing work if my internet is down?
Yes — LekhaPro is a desktop app; billing, stock and GST all run offline, so a dropped connection never stops the counter.
Can it print thermal receipts?
Yes — 80mm thermal receipts print silently to your chosen printer, and A4 tax invoices are also supported.
Does it track stock?
Yes — stock updates on every bill, with valuation and low-stock alerts.
After the internet returns, must I re-enter the bills I raised?
No. Each bill was saved as it was raised, into the database on the counter machine, complete with its series number, its stock effect and its tax. There is no upload queue and no reconciliation afterwards. Only the documents that genuinely need the portal — an IRN or an e-way bill — remain outstanding when the line comes back.
How should I handle e-invoicing on a day the line is down?
Bill normally. The invoice is complete, numbered and handed to the customer, and its e-invoice payload is prepared alongside it. When the connection returns, the pending documents go through your GST Suvidha Provider and carry their IRN. Where goods must move that day, follow the documentation your consultant advises for a portal outage.
What exactly is included in Billing · offline?
works fully offline, GST-correct invoices, barcode scan-to-add, 80mm thermal or A4 printing, live stock & COGS and cash / credit / UPI capture, and 1 more. Every item on that list is a working screen you can open in the trial rather than a capability described in the abstract.
How is billing · offline handled differently here?
It rests on never stops for the internet, counter-fast and real books behind it. The distinction that matters is that these are structural rather than cosmetic — the behaviour is built into how records are posted, not layered on as a report you have to remember to run.
Does Billing · offline post to the real books?
Yes, and that is the whole reason it lives in this product rather than beside it. What never stops for the internet records lands in the same posted double-entry ledger the Trial Balance, P&L and GST returns are built from — so there is no second set of billing · offline numbers to reconcile against the first.
Does Billing · offline cost extra?
No. Billing · offline is part of the accounting core rather than a paid add-on, so counter-fast is there on the entry tier exactly as it is on the highest one. What the tiers change is reach and depth — devices, multi-branch and multi-warehouse reporting, and whether the conversational AI copilots are switched on.
Can I try Billing · offline before committing?
Yes — 14 days, no card. Test billing · offline against your own masters and your own transactions rather than sample data: the questions worth answering here are about your business's edge cases, and a demo dataset is built not to have any.
