What gst accounting should do for a small Indian business, what it should not pretend to do, and a free way to find out which side of that line you are on.
What most businesses actually need
In order of how often it hurts: raise a correct invoice quickly; know what is in stock; know who owes money and for how long; enter purchases without an evening lost to typing; hand the accountant something clean on the 5th.
A full chart of accounts appears nowhere on that list for most owner-run businesses, because their CA maintains it anyway from the same source data.
Buying for the list above, rather than for a feature comparison, is how businesses end up with software they still use in a year.
Where billing ends and accounting begins
These are two products and the line between them is worth knowing before buying either, because buying the wrong size is the usual mistake.
Billing is the front of the business: issuing invoices, holding customers and items, stock, knowing what is unpaid, and producing the figures a GST return is built from. Accounting is the whole ledger: a chart of accounts, journal entries, bank reconciliation, depreciation, payroll, and a trial balance that a balance sheet and a profit and loss statement come out of.
Most small businesses need the first continuously and the second periodically. That is why the common and cheapest arrangement is to bill in a billing system and give the accountant clean exports at the end of a quarter or a year — nobody is then making journal entries who should not be.
This product sits on the billing side: GST documents, stock, receivables, and exportable figures. It does not produce a balance sheet, and saying it did would only waste your time and your accountant's.
What Billixo covers
- GST invoicing with the full Rule 46 field set and the tax split derived from place of supply.
- Inventory that decrements as you bill, with low-stock warnings before you run out mid-order.
- Purchases entered from a photograph of the supplier bill — supplier, GSTIN, lines and tax as a draft you check.
- Payments and part payments recorded against invoices.
- Receivables with ageing, so the follow-up list writes itself.
- Recurring invoices for anything billed on the same day each month.
- Proforma invoices and quotations in the same numbering discipline.
- GSTR-1 and GSTR-3B summaries exported for filing or for your CA.
- Bulk import and export — CSV and Excel in; CSV, Excel and JSON out.
- Team logins on the paid plans, each with their own credentials.
What it does not do
- A full general ledger with a chart of accounts and journal entries.
- Payroll.
- Manufacturing costing, bill of materials and work orders.
- Multi-currency consolidation.
- Statutory audit and financial statement preparation.
- If you need these, you need accounting software, and it is better to know that now than after a migration.
Setting up in about twenty minutes
- Open the free account and enter your business name, GSTIN and state.
- Add your products with HSN codes, rates and opening stock.
- Add your regular customers with GSTIN and state.
- Add your regular suppliers.
- Raise one invoice and confirm the stock moved.
- Enter one purchase — photograph the bill if you are on a paid plan or still inside the 14 days of full access.
- Look at the receivables list. That is your working screen from here on.
Inventory that stays accurate
Stock goes wrong for one reason above all others: it is maintained separately from billing. Two records, updated by two people, diverging quietly until somebody counts.
The fix is not better discipline, it is a single source: stock that moves because an invoice was raised, not because someone remembered to adjust it. Purchases increase it, sales reduce it, and the count is a check rather than a reconstruction.
Low-stock warnings then become useful rather than noise, because the number they are based on is real.
Working with your accountant
The handover that works is a file, not an account. GSTR-1 and GSTR-3B summaries, a purchase register that reconciles to 2B, and exports in CSV, Excel or JSON.
That leaves your CA free to work in whatever they use, and leaves you free to change billing software later without a negotiation. Both of those are worth more than an integration that ties you to one practice.
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.
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.
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
Is this full accounting software?
No. It is billing-led: invoices, purchases, inventory, payments, receivables and GST summaries. There is no general ledger, no payroll and no manufacturing costing. For most small businesses that is the right scope, because the CA maintains the ledger anyway.
Does stock update automatically when I bill?
Yes. Inventory decrements on sale and increases on purchase, with low-stock warnings. The point is that there is one number rather than two records drifting apart.
Can I enter purchases as well as sales?
Yes, and on the paid plans you can enter them from a photograph of the supplier bill — supplier, GSTIN, lines and tax come back as a draft you check rather than a form you fill.
Can more than one person use it?
On the paid plans, yes — team logins with their own credentials. The Free plan is a single login, which suits a one-person operation and is usually the first limit a growing business hits.
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.
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.
