If you searched free gst bill software, you have probably already found three products where "free" meant fourteen days. Here is what free means on this one, what it includes, and exactly where it stops.
Free software, and the part nobody mentions
The question with free gst bill software is never really "is it free". It is "what happens when it stops being enough".
With a downloaded free tool, usually nothing good: no export path, a database file on one machine, and a rebuild from scratch when you outgrow it. With a free plan on a real platform, the answer is that you change a plan and keep everything.
That is the difference worth caring about, and it is invisible on the day you sign up.
How to tell an honest free plan from a trap
- Can you export everything, in full, on the free plan? This is the only question that really matters. Records you cannot take out are not records you own.
- Does it expire? A trial that calls itself a plan is the most common sleight of hand here.
- Is the document a real tax invoice — place of supply, HSN or SAC per line, the tax heads shown separately — or a watermarked sample?
- Are the limits readable? A stated volume cap and one login are honest limits. "Fair use" is not a limit, it is a reservation.
- What happens to your data if you stop using it? "Locked" and "deleted" are both answers worth knowing before you start.
- Are there ads or someone else's branding on the invoice your customer receives?
- What does the next tier cost, and is it the tier you will need within a year?
What the free plan includes
- Real GST invoices — GSTIN, HSN/SAC on every line, place of supply, the correct CGST/SGST or IGST split, and a consecutive series that restarts each financial year.
- Customers and products, with GSTIN, state, HSN and default rates stored once and reused.
- A daily and monthly invoice allowance sized for a small operation.
- One login, which suits a one-person business.
- Payments recorded against invoices, with an outstanding list.
- Full data export — CSV, Excel and JSON — on the free plan, not just the paid ones.
- Nothing to install. It runs in a browser, on a laptop or a phone.
- Fourteen days of the complete paid product on every new account, then it settles onto Free.
What the free plan does not include
- A watermark-free PDF. The free invoice carries a small mark.
- GSTR-1 and GSTR-3B export. The invoices are compliant; the return summaries are a paid feature.
- The AI features — bill scanning, HSN lookup, the assistant, written reminders.
- Extra team logins. Free is a single user.
- Bulk import from CSV or Excel. Export is free; import is not.
- Recurring invoices and payment reminders.
- WhatsApp sharing and custom invoice branding.
- These are the conveniences, not the compliance. Nothing on this list affects whether your invoice is valid.
Getting started on the free plan
- Open the free account — an email address and a password, no card.
- Enter your business name, GSTIN and state. This is what the tax logic works from, so it is worth getting right.
- Add your first customer with their GSTIN and state.
- Add a few products with HSN codes and rates.
- Raise an invoice. Check the tax split — it should already be correct.
- Send the PDF, and carry on. Nothing expires and nothing needs deciding today.
When free stops being enough
The free plan usually runs out in one of three recognisable ways, and none of them are sudden.
You hire someone and need a second login. You start needing the GST return export every month instead of assembling it by hand. Or you hit the invoice ceiling in the last week of a good month.
At that point upgrading takes a minute and nothing moves — same data, same invoices, same customers, with the caps lifted. And because the plans are bought for a term with no auto-renewal, the decision is never made for you by a card on file.
Is there free GST billing software from the government?
This comes up constantly, so: the GST portal is where returns are filed, and there have been accounting and billing offerings made available to small taxpayers through GSTN-empanelled providers over the years. What the portal itself is not is a day-to-day billing system for your counter.
The practical position for most businesses is that filing happens on the portal and billing happens somewhere else. The job of your billing software is to hand the portal — or your CA — clean, complete numbers.
That is a job a free plan can do perfectly well, which is why the free plan here produces full compliant invoices rather than a limited sample.
Invoice numbering: one unbroken series per year
The invoice number has to be consecutive, unique within the financial year, and no more than sixteen characters of letters, numbers, slashes and hyphens. Gaps invite questions. Duplicates cause them.
This is the single most common reason a spreadsheet-based billing setup fails an audit: two people billing on two machines, both starting from the last number they remember. A system that issues the number centrally cannot make that mistake.
The series restarts on 1 April, and Billixo restarts it for you rather than waiting to be told.
Credit notes, debit notes, and fixing a wrong invoice
An issued tax invoice is not something to edit. If the value was too high, or goods came back, the correction is a credit note that references the original invoice. If it was too low, a debit note. Both carry their own numbers and both appear in your return.
There is a deadline on the credit note that matters: the adjustment has to be declared by the return for the relevant month of the following financial year, or by the annual return, whichever comes first. Past that, the note exists commercially but the tax cannot be adjusted.
Software that lets you quietly retype an invoice raised last month is not doing you a favour.
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.
A note for accountants and CAs
If you are the person who has to make sense of a client’s billing at the end of the month, what you need from their software is narrow and specific: a complete outward supply summary, correct place-of-supply treatment, HSN present on every line, and an export you can open without repair.
Billixo produces GSTR-1 and GSTR-3B summaries and exports to CSV, Excel and JSON. Client-side, the invoice fields cannot be skipped, which removes the category of problem where the data was never captured in the first place.
What "free" means here, exactly
The Free plan costs nothing, needs no card, and has no expiry date. It is not a trial that turns into a bill; it is a plan you can run a small business on indefinitely.
What it gives you:
- Real GST invoices with the full Rule 46 field set
- Customers and products, with HSN/SAC held against each
- A daily and monthly invoice allowance, generous enough for a small operation
- One login
- Export of your own data, whenever you want it
What it does not give you:
- A watermark-free PDF
- GSTR-1 and GSTR-3B export
- The AI features — bill scanning, HSN lookup, the assistant
- Extra team logins, bulk import, recurring invoices and reminders
Every new account also gets the full paid feature set for its first 14 days, so you can see what the ceiling looks like before deciding whether you need it. When that ends nothing is charged and nothing is deleted — the account simply settles onto Free.
Start free now — it takes an email address and about a minute.
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
How many invoices can I raise for free?
The Free plan carries a daily cap and a monthly cap sized for a small operation. The exact numbers are on the pricing section of the home page, and they are visible inside the app as you use them, so you are never surprised.
What happens after the 14 days of full access?
Nothing is charged and nothing is deleted. The account settles onto the Free plan: the conveniences switch off and the volume caps apply, while every invoice, customer and product you created stays where it is.
Can I export my data on the free plan?
Yes — CSV, Excel and JSON, covering customers, products, invoices and payments. Export is deliberately free, because data you cannot get out is not data you own.
Can I move my existing customers and products in?
Yes. Bulk import from CSV or Excel on any paid plan, and export back out in CSV, Excel or JSON at any time, including on Free. Most people bring their party and item lists across in one pass and carry outstanding invoices as opening balances.
Will my accountant be able to work with it?
That is what the GSTR-1 and GSTR-3B summaries are for. They export in formats a practitioner can open and reconcile without repairing the file first — which, in practice, is most of what a CA wants from a client’s billing software.
Try it — the demo is the product
There is no sales call and no scheduled demo, because a recorded walkthrough of somebody else’s data tells you nothing about your own. Open an account instead and raise a real invoice for a real customer; it takes about a minute and costs nothing.
