GST Software for CA from a practice point of view — what to insist on in a client’s billing system, and what genuinely reduces the hours you spend per client per month.
Practice software and client billing are different purchases
Practice software handles many GSTINs, bulk filing, client management and deadlines. It is bought by the practice, and it is not what this page is about.
Client billing software produces the data you file from. It is bought by the business, and it decides how much of your month is spent repairing rather than reviewing.
Buying more practice software does not fix a client whose invoices never carried an HSN. Only the client’s billing system can fix that, which is why what they use is your problem too.
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.
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.
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.
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.
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.
Who this actually suits
It fits a business that raises between a handful and a few hundred invoices a month and would rather not think about GST between the 10th and the 20th: traders, distributors, retail counters, workshops, agencies, consultants, contractors and manufacturers who sell on invoice.
It fits less well if you need deep manufacturing costing, multi-currency consolidation, or payroll — those are different products, and pretending otherwise wastes your evaluation time.
If you are not sure which side of that line you fall on, the free plan answers it in an afternoon at no cost. Start free now.
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.
Where your data lives
On the server this platform is installed on. Every record carries a company identifier and every query is scoped to the signed-in account at the framework level, so one business cannot read another’s data by any route, including a crafted one.
Sign-in is rate limited, sessions can be restricted to one device per user, and passwords are stored hashed. Exports are available on every plan, free included: if you ever want to leave, your data leaves with you.
Frequently asked questions
Does it file returns?
No. It prepares GSTR-1 and GSTR-3B summaries and exports them. Filing stays with you or the client, which is where the responsibility sits.
What does it cost my client?
The Free plan is ₹0 with no card and no expiry. Paid plans are bought for a fixed term with no auto-renewal. Every new account gets the full paid feature set for its first 14 days.
Can I get the data in a format I can use?
CSV, Excel and JSON, covering customers, products, invoices and payments, plus the GST return summaries. Export works on every plan including the free one.
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.
Does it work on a phone?
Yes. It is a browser application that adapts to the screen, so the same account works from a desktop at the counter and a phone in the market. There is no separate app to keep in step.
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.
