Restaurant Bill GST should be the least interesting part of a working day. Here is how Billixo makes a GST-compliant bill take about forty seconds, and why the free plan is enough for most small businesses.
The real problem with restaurant bill gst
The bill itself is easy. What is hard is that a GST invoice is a legal document with about a dozen mandatory fields, and the person raising it at four in the afternoon is not thinking about Rule 46. They are thinking about the customer waiting.
So the fields get skipped. The HSN is left blank because nobody looked it up. The place of supply defaults to whatever the last invoice had. The tax splits into CGST and SGST because that is what the template does, even though the customer is in another state.
None of that hurts today. It hurts when your customer’s input credit does not appear, or when a return has to be amended, and by then it is twenty invoices old.
The fix is not discipline. It is software that cannot leave those fields empty because it derives them.
What Billixo does for restaurant bill gst
- Compliant invoices by default. Every Rule 46 field is on the invoice — GSTIN, HSN/SAC, place of supply, the tax split shown separately, a consecutive numbering series that restarts on 1 April.
- Tax worked out, not chosen. CGST/SGST or IGST follows from the place of supply against your registration state. There is no dropdown to get wrong.
- Customers and products remembered. GSTIN, state, HSN, rate and default tax sit on the record, so the second invoice to the same party is three clicks.
- A PDF a customer can read. Clean, printable, with your own logo and details on the paid plans.
- WhatsApp and email sharing. The way most Indian businesses actually deliver an invoice, built in rather than bolted on.
- Stock that moves as you bill. Inventory decrements on sale, with low-stock warnings before you run out mid-order.
- Payments and receivables. Record part payments, see what is overdue and by how long, and chase it with a written reminder rather than an awkward call.
- Recurring invoices. Anything billed on the same day every month goes out on its own.
- GSTR-1 and GSTR-3B summaries. The month closes as a download rather than a project.
- AI bill scanning. Photograph a supplier bill and it becomes a draft purchase record, lines and tax included.
- Proforma invoices and quotations. The document before the invoice, in the same series discipline.
- Bulk import and export. CSV and Excel in, CSV, Excel and JSON out — including on the free plan.
Raising a GST invoice, start to finish
- Pick the customer. Their GSTIN, state and place of supply come with them; a new one takes twenty seconds to add and is remembered afterwards.
- Add the lines. Products carry their own HSN, rate and tax, so a line is a name and a quantity.
- Look at the tax. CGST and SGST, or IGST, already split and totalled from the place of supply — check it rather than compute it.
- Save. The invoice number is issued from the series automatically, so there is no gap and no duplicate.
- Send it. WhatsApp, email, or download the PDF — usually before the customer has left the counter.
- Forget about it. It is in the GSTR-1 summary, in your receivables, and in the stock movement, without a second entry anywhere.
What the month-end actually looks like
The test of billing software is not the invoice. It is the fifth of the following month, when the outward supply summary has to reconcile to what you actually billed.
Because every invoice here carried its place of supply, its HSN and its correct tax split at the moment it was raised, the summary is a report rather than a reconstruction. GSTR-1 and GSTR-3B summaries export in formats a practitioner can open directly.
The invoices that do not reconcile are the ones that were raised without the fields. There is no software that can add them back afterwards — which is why capturing them at source is the whole argument.
Paper, Excel, and when to stop
There is nothing wrong with a bill book while a business is small. The point at which it stops working is specific and recognisable: when you cannot answer "who owes me money and for how long" without an afternoon, or when two people are billing and the numbering has gone.
Excel lasts longer and fails more expensively, because it looks like it is working right up until the return does not tie out. A spreadsheet does not enforce a numbering series, does not know the place of supply, and does not stop the same invoice number being used twice on two laptops.
The move does not have to be expensive — the free plan exists precisely so the decision is not about money.
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.
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.
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
Can I send the invoice on WhatsApp?
Yes. WhatsApp and email sharing are built in on the paid plans, so the invoice reaches the customer from the same screen you raised it on rather than through a download-and-attach detour.
What about invoices I have already raised elsewhere?
Bring the parties and items across by bulk import, and carry the unpaid invoices in as opening balances. Most businesses do not migrate historic invoices at all — they keep the old system readable and start the new series from a clean cut-off date.
Does it handle part payments?
Yes. Record what came in against an invoice and the balance stays visible on the receivables list, ageing as it goes, so a partly-paid invoice never quietly disappears from the follow-up.
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.
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.
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.
