Low Cost GST Billing Software varies more than the products do. Here is how to compare it properly, and why the honest starting number here is ₹0.
The three ways GST software is priced
Per user, per month. Cheap to start, and it grows exactly as your team does. Fine if headcount is stable; unpleasant if it is not, and it quietly discourages giving people their own logins — which is bad for your audit trail.
Per invoice or per document. Rare but it exists. It prices your growth, and it makes you think about cost at the moment you should be thinking about the customer.
Per term, flat. One payment for a period, everything included. Predictable, and the model Billixo uses — bought for a fixed term, no auto-renewal, no card kept on file.
None is dishonest. But they behave very differently at three times your current size, and that is the number worth modelling before you commit.
Cheapest, and where that goes wrong
Buying on price alone works out badly here more often than in most software categories, and for a specific reason rather than a general one about quality.
The failure modes of cheap billing software are predictable. Export is a paid feature, so your records are leverage rather than yours. The invoice is not actually compliant — one combined tax figure, no place of supply, no HSN column — which is discovered at return time across a year of invoices. Compliance updates stop, so the return format it exports is last year's. The second login costs more than the whole first plan, which is discovered when you hire. And support does not answer in the week a return is due.
Any one of those costs more than the difference it saved. The export one is the worst, because it is the one that makes leaving expensive.
The sane way to buy cheaply is to start free, use it properly for a month with your own data, and pay only for the specific thing you ran out of. That way the price is matched to a need you have actually felt rather than to a feature list.
How Billixo is priced
- Free plan — ₹0. No card, no expiry. Volume limits, one login, a watermark on the PDF, no GST return export and no AI features. Everything else works.
- Paid plans — bought for a term. One payment for the period, not a subscription.
- No auto-renewal. No card is kept on file. When a term ends the account settles back onto Free rather than stopping or charging.
- No per-invoice charge. Volume is a plan limit, not a meter.
- Team logins included on the paid plans rather than sold per seat.
- Export on every plan, free included — CSV, Excel and JSON.
- Fourteen days of the full paid product on every new account, free, so you know what you are buying before you buy it.
- A money-back window on paid purchases, stated on the pricing section.
Working out what you should actually pay
- Count your invoices in a normal month, and in your busiest month. The busy month is the number that matters.
- Count how many people need to raise an invoice or see the numbers. That decides whether per-user pricing works for you.
- Decide whether you need the GST return export monthly, or whether your CA assembles it anyway.
- Decide whether the AI features — bill scanning especially — would actually save you time. If you enter more than twenty purchase bills a month, they will.
- Start on the free plan and see which limit you hit first. That limit is what you are buying, and nothing else.
Free, cheap, and expensive — in the long run
The cheapest software in this market is not the one with the lowest price. It is the one that stops you making the expensive mistakes: wrong tax heads, broken invoice series, a return that does not reconcile, purchases entered twice.
That is why the free plan here is a real plan rather than a demo. If a ₹0 tier removes those mistakes for a small business, the business should be allowed to stay on it — and upgrade when its own growth, not a countdown, makes the case.
Why we do not publish competitors’ prices
Pages comparing low cost gst billing software usually list every vendor’s pricing in a table. Those tables are almost always out of date, and being wrong about somebody else’s prices is both unfair to them and useless to you.
Ours are on the home page and are current by definition. For anybody else’s, go to their site. Any comparison table on a vendor’s own website — including this one — should be read with that in mind.
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.
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.
Who this actually suits
It fits a business that raises between a handful and a few hundred invoices a month and would rather not think about GST between the 10th and the 20th: traders, distributors, retail counters, workshops, agencies, consultants, contractors and manufacturers who sell on invoice.
It fits less well if you need deep manufacturing costing, multi-currency consolidation, or payroll — those are different products, and pretending otherwise wastes your evaluation time.
If you are not sure which side of that line you fall on, the free plan answers it in an afternoon at no cost. Start free now.
The price, plainly
Free is ₹0 and stays ₹0. The paid plans are bought for a fixed term, paid once, with no auto-renewal and no card kept on file — when a term ends the account drops back to Free until you decide to buy again.
There is no per-invoice charge, no per-user surprise on the free plan, and no feature that is technically included but practically throttled. What the plan says you get is what you get.
Compare the plans on the home page, or just start free now and look at the ceiling from the inside.
Where your data lives
On the server this platform is installed on. Every record carries a company identifier and every query is scoped to the signed-in account at the framework level, so one business cannot read another’s data by any route, including a crafted one.
Sign-in is rate limited, sessions can be restricted to one device per user, and passwords are stored hashed. Exports are available on every plan, free included: if you ever want to leave, your data leaves with you.
Frequently asked questions
Is there a monthly subscription?
No. Plans are bought for a term and paid once. Nothing auto-renews, and no card is kept on file — when a term ends the account settles back onto the Free plan until you choose to buy again.
Do you charge per user?
No. Team logins are included in the paid plans rather than sold per seat. The Free plan is a single login.
Do you charge per invoice?
No. Volume is a plan limit rather than a meter, so a busy month costs the same as a quiet one.
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.
See it working on your own bills
The fastest way to judge billing software is to bill with it. Photograph one supplier invoice, raise one sales invoice, and look at the PDF your customer would receive.
