Best GST Billing and Accounting Software means different things to different businesses. Here is what a billing-led system genuinely covers, where full accounting software starts, and how to tell which one you are shopping for.
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.
CGST, SGST and IGST — worked out, not chosen
Whether a sale attracts CGST and SGST or IGST is not a preference. It follows from the place of supply: same state as your registration means the tax splits into central and state halves, a different state means one integrated tax at the combined rate.
That sounds simple and goes wrong constantly, because it is a dropdown in most billing software and a dropdown is something a tired person clicks past. In Billixo the split is derived from the state on the customer record against the state on your registration, and it changes the moment either does.
The consequence of getting it wrong is real: an IGST invoice raised as CGST/SGST has to be credited and reissued, and if the return has already gone in, amended.
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.
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.
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.
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 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.
Can I import my existing item and party lists?
Yes, by bulk import from CSV or Excel on the paid plans. Export is available on every plan including the free one.
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.
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.
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.
