A straight answer on gst billing online free: the Free plan here costs nothing forever, the invoices it produces are legally compliant GST invoices, and your data exports whenever you want it. The caps are on volume and conveniences, not on whether it works.
What "free forever" means here
The Free plan is ₹0 and stays ₹0. There is no card on file, so there is no mechanism by which you could be charged by accident, and nothing to cancel if you walk away.
It has volume limits and it leaves out the paid conveniences — that is how it can exist. But the invoices it produces are proper GST invoices with the full Rule 46 field set, the tax split is derived correctly, and your data exports in CSV, Excel and JSON whenever you want it.
Separately, every new account gets the complete paid feature set for its first fourteen days. When that finishes nothing is charged and nothing is deleted: the account settles onto Free and carries on.
Free and online: what to verify first
The practical appeal of working in a browser is not the invoice; it is that nothing is stranded. The same records from the shop computer, from a phone at a customer's site and from home, with no question about which copy is the real one — because there is one.
It also moves the parts a file cannot hold: the numbering series issued centrally so it cannot collide, customers and items entered once, and the document generated from the record rather than typed into a layout.
Before trusting any free online system with billing records, verify three things in this order. Can you export everything, in full, in a format you can open, on the free plan? What happens to your records if you stop using it — exportable, locked, or deleted? And does the free plan expire?
The fair objection is connectivity, and at a counter with unreliable internet it is a real one: no connection means no bill. Here, export is on every plan including the free one, and the free plan does not expire — so records never end up behind a payment.
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.
Free download versus free online
A lot of gst billing online free searches are really looking for a download: an .exe, installed once, working forever, offline.
That model has one genuine advantage — it keeps billing when the connection drops — and several costs that only show up later. The data lives on one machine, so backup is your problem and a failed hard disk is a catastrophe. Nothing bills from a second location. Updates for law changes are a manual job.
Billixo runs in a browser, so there is nothing to download, nothing to update, and no single machine holding your business. If offline billing is genuinely non-negotiable for you, that is a fair reason to choose differently — it is worth deciding deliberately rather than by default.
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.
HSN and SAC codes, and how many digits you need
Every line on a tax invoice needs an HSN code for goods or a SAC for services. How many digits depends on your aggregate turnover in the preceding financial year — smaller businesses report fewer digits than larger ones, and B2B and B2C invoices are treated differently.
Because the requirement is tied to turnover and has been tightened in stages, the practical answer is to store the fullest code you can against each product once, and let the software report at the level required. A six-digit code can always be truncated; a two-digit one cannot be expanded.
Billixo keeps the code on the product record and carries it onto every line automatically, and its AI HSN lookup will suggest one from a plain description when you genuinely do not know.
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.
The AI, and what it is actually for
The useful application of AI to billing is not a chatbot. It is the twenty minutes a day spent retyping things that already exist on paper.
- Scan a supplier bill. Photograph it; the lines, the GSTIN, the tax and the totals come back as a draft you check rather than a form you fill.
- Find the HSN code. Describe the product in plain words and get a code to confirm, instead of scrolling a list of eleven thousand.
- Ask about your own numbers. "What is outstanding over sixty days?" answered from your data, not a manual.
- Write the reminder. A polite, specific chase for an overdue invoice, ready to send on WhatsApp.
Nothing is sent anywhere until you ask for it, and the platform runs on whichever model it has been configured with — including one hosted on your own server.
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.
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.
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
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.
Is free GST billing software safe to use for a real business?
The invoices are as valid as any other, provided they carry the mandatory fields — which these do. What to check with any free tool is the export path and where your data lives, because those are what determine whether you are stuck later.
Do I have to upgrade eventually?
Only if a limit gets in your way. Plenty of one-person businesses run on the free plan indefinitely. When you do upgrade it is a fixed-term purchase with no auto-renewal, and the account falls back to Free rather than stopping if you do not renew.
Is my data shared with anyone?
No. It sits in this installation, scoped to your company. AI requests only happen when you explicitly ask for one, and nothing is sent anywhere otherwise.
Is it really free?
Yes. The Free plan is ₹0, needs no card and has no expiry. It has volume limits and leaves out the paid conveniences — watermark-free PDFs, GST return exports, the AI features, extra logins — but the invoices it produces are real GST invoices, and you can export your data from it whenever you like.
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.
