For CA firms running 80–300 clients
Your whole client book. Reconciled. Ready to sign.
Turn monthly GST grunt work into minutes of exception review — you review and sign; we do the rest.
- You review and sign every return
- India-region data storage
- Full audit trail
- Your data is never used to train shared models
The problem
Every month, the same vise.
GSTR-1 on the 11th. 2B reconciliation from the 13th to the 18th. GSTR-3B on the 20th. Not for one client — for every client at once.
So the work gets rushed, or it gets pushed to a junior, and either way a partner spends half the month reviewing grunt work instead of advising. A missed mismatch is a client's ITC gone. A wrong figure is a notice with your name on it.
The tools that exist reconcile one client at a time and leave the judgment — and the risk — entirely on you.
The outcome
The bulk reconciles itself. You see only what needs a decision.
FinOps Brain matches the Purchase Register against GSTR-2B and clears everything it can account for. What's left is a short, ranked exception queue — each item with the reason, the evidence behind it, and a suggested action. You approve or correct with one click. Nothing is filed without you.

Suggested: Short by ₹450 — likely a rounding or rate difference. Confirm against the invoice, then accept or correct.
You sign every return
The sign-off is always yours; nothing is filed without your review.
India-region data
Client data is stored in India, in line with how CA firms are expected to hold it.
Full audit trail
Every match, correction, and approval is logged and attributable.
Never used to train shared models
Your client data stays yours; it does not train models used by anyone else.
How it works
Three steps. The judgment stays with you.
- 1
Upload the Purchase Register and GSTR-2B.
Bring in a client's books and their 2B for the period. One client or the whole book.
- 2
The engine reconciles the bulk.
A deterministic-first cascade — exact match, then fuzzy match, then a confidence score — clears everything it can account for and flags the rest.
- 3
You review the exceptions and sign.
A ranked queue with reasons and evidence. Approve or correct each item, then file with your sign-off.
Why firms use it
Built around how a CA firm actually works.
Safety
Catch the ITC risks and mismatches before they cost your client.
Every exception comes with its evidence and an audit trail, and the numbers are yours to verify — not a score to trust on faith.
Capacity
Clear the grunt work; free your team for billable advisory.
Hours back per client, per month — and more clients handled without adding headcount.
Control
You review and sign — nothing filed without you.
A short exception queue, one-click approve or correct, and the sign-off always yours.
For the firm
One cockpit for your whole client book, not one client at a time.
A firm-level view across every client, so a partner can see the whole month at a glance.
For the firm, not one client
A cockpit for the practice — not another single-client tool.
Most reconciliation tools were built for one business looking at its own GST. A CA firm is not one business — it is 80, 200, 300 of them, every month, on the same deadline.
FinOps Brain is built for that reality: the whole client book in one place, the exceptions ranked across all of them, and the partner's time spent where judgment is actually needed. It arms the firm; it does not step into the sign-off that only a CA can give.
From the founder
Built with CA firms, not at them.
FinOps Brain is being built by a technical founder working across two worlds — the GST regime as CA firms actually operate it, and the engineering of the AI systems underneath. The reason those two things sit together here is simple: reconciliation is a judgment task wearing a data-entry costume, and getting it right needs both.
We're building this alongside a small number of founding CA firms — not shipping a finished product at you, but shaping it against real month-ends, real client books, and the standard you actually sign to. If that's the kind of partner you'd want at the table, we'd like to talk.

A 20-minute demo — we'll walk the exception queue on a real reconciliation and answer the questions a CA actually asks.
