A note on gst software for ca by icai, written for practitioners: the reason client work takes so long is almost never the filing. It is reconstructing data that was never captured. This page is about fixing that end.
Where the hours actually go
Ask any practitioner where client time disappears and the answer is consistent: chasing missing GSTINs, correcting place-of-supply treatment, filling in blank HSN codes, explaining a broken invoice series, and matching purchases against 2B from a register that was typed from paper.
None of that is filing. All of it happens because a field was optional in the client’s software at the moment the invoice was raised.
The highest-leverage change available to a practice is not a better filing tool. It is getting clients onto billing software where those fields cannot be skipped.
What Billixo gives you as the client’s accountant
- Mandatory fields captured at source — GSTIN, place of supply, HSN on every line, correct tax split.
- A consecutive invoice series issued centrally and restarting each financial year, so gaps and duplicates do not happen.
- GSTR-1 and GSTR-3B summaries that reconcile to what was billed.
- Exports in CSV, Excel and JSON that open without repair.
- Credit and debit notes that reference the original invoice properly.
- A purchase register that keeps the supplier’s own invoice number and date, which is what 2B matching depends on.
- A free plan for the client at ₹0 — so recommending it costs them nothing and removes your objection about client budget.
Putting a client on it
- Have them open a free account — ₹0, no card, so there is nothing to approve.
- Set up the business details yourself if it is quicker: GSTIN, state, registration type.
- Import their party and item lists from whatever they have in Excel.
- Set the HSN codes properly once. This is the twenty minutes that saves you an hour every month afterwards.
- Agree a cut-off date and let them bill from it.
- Take the GSTR-1 export at month end and compare it to what you would have assembled by hand. That comparison is the whole business case.
What to insist on, whatever they choose
If a client will not move, these are worth insisting on in whatever they already use: GSTIN mandatory on B2B parties; place of supply set on the party rather than the voucher; HSN on every item master; one person responsible for the invoice series; purchases entered with the supplier’s exact invoice number and date.
Those five habits remove most of the month-end repair regardless of the software. The advantage of a system that enforces them is only that it does not depend on anyone remembering.
The handover, and why a file beats a login
Some products offer accountants a login into the client’s account. That is occasionally useful and usually not what you want — you work in your own tools, across many clients, and a login per client is a burden rather than a service.
A clean export is better: GSTR-1 and GSTR-3B summaries, a purchase register, and CSV or Excel of the underlying documents. It fits your workflow instead of asking you to adopt theirs.
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.
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
Can I set the client up myself?
Yes, and it is usually faster. Twenty minutes on business details, party and item masters and HSN codes removes most of the recurring monthly work.
What if the client already uses something else?
Then the useful conversation is about five habits rather than a migration: mandatory GSTIN on B2B parties, place of supply on the party master, HSN on every item, one owner of the invoice series, and purchases entered with the supplier’s exact invoice number and date.
Is this software for my practice or for my clients?
For your clients. It is billing software, not practice management or bulk filing software. What it does for you is produce data that does not need reconstructing.
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.
