What billing app means in practice, what each option costs you when something goes wrong, and a free plan to test the answer on rather than take anyone's word for it.
The question that decides it for most businesses
Not features. Two things: how reliable is your internet, and how many people bill?
If your connection drops for hours at a time and one person does all the billing at one counter, installed software is genuinely the better engineering choice, and no amount of enthusiasm about the cloud changes that. If more than one person bills, or you need the figures from somewhere other than the shop, the cloud wins on the thing that actually breaks — two copies of a file and two numbering series.
Everything else is preference. These two are consequences.
Billing from a phone
Billing from a phone is genuinely useful in some trades and awkward in others. It suits anyone who bills where the work is — a service visit, a delivery, a site, a market stall. It does not suit a counter with a queue, where a physical keyboard, a scanner and a real printer are faster than any phone.
This works on a phone browser rather than as an app from a store. There is no listing to install; you open the site, sign in, and the screens are built to work at that size. You can add it to your home screen so it opens like an app.
The question worth asking about any billing app, including the ones that are real apps, is where the data lives. If it lives on the phone, a lost or wiped phone is a lost set of records, and app-only products that keep a local database are a genuine risk for a business. Here the records are on the server, so the phone is just a window — losing it costs you a phone.
Printing from a phone is the real limitation. Sharing the PDF on WhatsApp usually works better than trying to print, and for many service businesses that is what the customer wanted anyway.
What the free plan actually includes
- Complete GST tax invoices, every legally required field, tax split per line.
- Nothing to install — a browser on any computer, tablet or phone.
- Customers and items stored once, with GSTIN, state, HSN or SAC and rate.
- One numbering series, issued centrally and consecutive within the financial year.
- Stock that moves as you bill.
- A receivables position — what is unpaid, aged, per customer.
- PDF invoices to print, email or send on WhatsApp.
- Full export to CSV, Excel and JSON, on every plan including this one.
- ₹0 — no card, no expiry, not a trial.
Trying it in five minutes
- Start free now — an email address and a password. No card, no download.
- Enter your business name, address and GSTIN.
- Add two or three of your own items with their HSN codes and rates — ideally at two different rates.
- Raise a real invoice and check the tax computed per line.
- Print it on the printer you actually use, or share the PDF to your own phone.
- Raise a second one and confirm the number advanced by itself.
- Export everything and open the file, so you know you can leave.
Where your data is, and how to stay able to leave
With installed software the data is on your machine, and the risk is losing it — a failed disk, a theft, a reformat. With a hosted system the data is on a server, and the risk is different: not losing it, but not being able to take it with you.
The protection against the second is export, and it is worth being specific about what good export looks like. Everything, not a summary. A format you can actually open — CSV, Excel or JSON rather than a proprietary archive. Available whenever you want it rather than on request. And on every plan, because an export that requires a payment to use is a lock.
The question to ask any vendor is what happens to your records if you stop paying. "They are deleted" and "the account is locked" are both answers that should end the conversation for a business keeping statutory records.
Here, export is on every plan including the free one, and the free plan does not expire — so an account cannot lapse into a state where your own records are unreachable.
The hardware question, answered honestly
Browser-based billing works with ordinary hardware, with one real caveat worth knowing before you buy anything.
Printers work the way they work for any web page: if your computer can print to it, this can print to it, including a thermal roll printer with the right paper size set. A USB barcode scanner behaves as a keyboard, so it types the code into the field — nothing special is needed. A phone or tablet works for billing but is poor for printing.
The caveat is deep hardware integration. A browser cannot talk directly to a weighing scale, a fuel dispenser, a cash drawer on a serial port or a card terminal. If your counter depends on the scale posting a weight into the bill, that needs installed software with a driver, and no web application will do it.
So the test is not "will it work with my printer" — it almost certainly will. It is "does anything at my counter need to speak to the software directly". If something does, that decides it.
Reverse charge, exports and the supplies that behave differently
Not every supply is a straightforward taxable sale. Some notified supplies put the tax liability on the recipient rather than the supplier. Exports and supplies to an SEZ can be made under a bond or LUT without payment of tax, or with tax and a refund claimed afterwards. Composition dealers cannot charge tax at all and must say so on the bill.
Each of these changes what the invoice has to say — the reverse charge marking, the LUT reference, the "composition taxable person" declaration. They are not exotic cases; most businesses hit at least one.
The fields are on the invoice in Billixo whether or not you use them, so the day you need one you are not looking for a workaround.
What a GST invoice legally has to carry
Rule 46 of the CGST Rules sets out what a tax invoice must show, and it is a longer list than most invoice templates carry. Getting one field wrong does not usually cost you anything the day you raise it — it costs your customer their input credit months later, which is a harder conversation.
The fields are:
- Your name, address and GSTIN
- A consecutive invoice number, unique within the financial year
- The date of issue
- The customer's name, address and GSTIN where they are registered
- Place of supply, and the state code, for inter-state supplies
- HSN or SAC against every line
- Description, quantity, unit, rate and taxable value per line
- Rate and amount of CGST, SGST/UTGST, IGST and cess, shown separately
- Whether tax is payable on reverse charge
- Signature or digital signature of the supplier or an authorised person
Billixo fills these in from the customer and product records rather than asking you to remember them, which is the only reliable way a busy counter gets them all right every time.
Bill scanning, in practice
The single largest time cost in most small businesses is not raising invoices — it is entering purchases. A photograph of a supplier bill goes in and a structured draft comes out: supplier, GSTIN, line items, rates, tax split and total.
You check it. That is the workflow, and it is deliberate: an extraction you did not read is a liability, not a saving. But checking a filled form takes fifteen seconds and typing one takes three minutes, and that difference compounds over a month of purchases.
Who it is built for
Small and mid-sized Indian businesses that are registered under GST and bill regularly. One person doing everything, or a counter with three people billing at once and an accountant who needs the month to close cleanly.
The design assumption throughout is that whoever raises the invoice is busy and is not a tax specialist. So the tax is computed rather than asked for, the compliance fields are populated rather than presented as questions, and the report the accountant wants is a download rather than a request.
Try it free — the free plan needs no card and does not expire.
Free, and what it costs you instead
Free software usually costs you something that is not money: your data held hostage, an export that does not work, ads inside your invoice, or a "free" tier so narrow it is a demo with a login screen.
The line here is drawn differently. Export works on the free plan — CSV, Excel and JSON — because data you cannot get out is not data you own. The invoice is a real compliant invoice, not a sample. The limits are on volume and on the conveniences, not on whether the thing works.
Start free now. If it does not suit you, take your data with you.
Reliability, backups and getting your data out
Cloud billing software is only as good as its worst day. Two things matter more than any feature list: that your data is backed up somewhere you can reach, and that you can export it in a format something else can read.
Exports here are CSV, Excel and JSON, on every plan including the free one, covering customers, products, invoices and payments. That is the honest test of whether software respects you — not what it promises, but what it lets you take when you leave.
Frequently asked questions
What happens to my data if I stop using it?
It stays exportable. Export to CSV, Excel and JSON is on every plan including the free one, which does not expire — so you are never in a position where your own records are locked behind a payment.
Is there an installer or a setup file to download?
No. It runs in a browser, so there is nothing to install, nothing to update and nothing tied to one machine. If you specifically need installed software with a local database, this is not the right product and installed alternatives are a reasonable choice.
Does it work offline?
No. It needs a working internet connection to issue a bill. If your counter loses internet for hours at a time that is a genuine reason to choose local software instead — better to know before you move your data than after.
What happens to my data if I stop paying?
Nothing is deleted. The account settles back onto the Free plan: the paid conveniences switch off, the volume limits return, and every invoice, customer and product you created stays exactly where it is — including the export.
Does it work on a phone?
Yes. It is a browser application that adapts to the screen, so the same account works from a desktop at the counter and a phone in the market. There is no separate app to keep in step.
Start free, decide later
You do not have to choose a plan to begin. Start on Free, use it for as long as it suits you, and upgrade only when a limit actually gets in your way — never automatically, and never because a countdown ran out.
