What accounting billing software 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.
Billing, invoicing, accounting — which one you are buying
The words are used loosely and the products are not interchangeable, so it is worth being precise about the three.
Invoicing is the narrowest: producing the document. Billing adds the records around it — customers, items, a numbering series, stock, and what is unpaid. Accounting is the whole ledger: journals, bank reconciliation, depreciation, payroll, and the statements that come out of a trial balance.
Most searches for "accounting software" by a small business are really for the middle one, because the questions behind them are "who owes me money" and "what do I give my accountant" rather than "what is my depreciation schedule".
The arrangement that works for most small businesses: bill and keep records in a billing system continuously, and let an accountant do the accounting periodically from clean exports. The expensive alternative is a ledger nobody posts to correctly, which produces statements that have to be rebuilt anyway.
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.
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.
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.
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 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.
Will my CA be able to work with the data?
Yes. GSTR-1 and GSTR-3B summaries plus CSV, Excel and JSON exports of customers, products, invoices and payments. That is what a practitioner actually wants — a clean file, not a login.
Is there a free plan?
Yes — ₹0, no card, no expiry, with volume limits, one login and a watermark on the PDF. Every new account also gets the complete paid feature set for its first 14 days.
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.
