Ask a practising CA how the firm made money last year and you will get a confident answer. Ask which specific hours of work never turned into an invoice, and the room goes quiet. That silence is work-in-progress, and in most practices it is the single largest, least-measured leak. The return got filed. The certificate got signed. Somewhere in between, three days of a partner's attention, a week of an article's time, a scope that quietly expanded, never made it onto a bill. The client is happy. The firm is poorer, and nobody logged why.

WIP is money you have already earned

Work-in-progress is simply effort you have delivered but not yet invoiced. It is not theoretical; it is salaried hours already paid for, sitting on assignments, waiting to become revenue. In a manufacturing business you would never let finished goods pile up in a warehouse unrecorded. In a professional practice, unbilled WIP is exactly that pile, except it is invisible, so it never triggers the instinct to sell it. The larger the firm and the more partners billing informally, the bigger the pile, and the easier it is for a scope that grew from "a quick GST reconciliation" into a fortnight of work to still go out at the original quote.

Why filing software cannot see the leak

This is not a criticism of the tools most practices run, it is a description of what they are for. Suvit and Vyapar's TaxOne, SAG Infotech's Genius, CompuTax, Winman, these are filing and compliance engines, and they are good at it: they pull data, prepare returns, compute tax, and push to the portals. That is genuinely hard software and it saves real time. But a filing engine's job ends when the return is filed. It does not know that the assignment took twice the time quoted, it does not hold your engagement letter, it does not track which partner spent what on which client, and it does not turn any of that into an invoice. It was never meant to. The leak is not inside the filing tool; it is in the space the filing tool was never built to cover.

Scope creep on fixed-fee jobs that no one re-quotes.
Time spent by seniors and partners that is never recorded against a client.
Assignments completed and delivered but not invoiced for weeks, or at all.
Out-of-pocket costs and government fees that never make it onto the bill.
Repeat ad-hoc advice to a good client that everyone quietly treats as free.

Bill it back with the right SAC code

When you do convert WIP into an invoice, the SAC code matters, and this is a place people get sloppy. Professional services by a CA fall under heading 9982. Financial auditing sits under SAC 998221, accounting and bookkeeping under 998222, payroll under 998223, and tax consultancy and preparation under 99823, that is 998231 for corporate and 998232 for individual. All of it is taxed at 18% GST. It is worth being precise, because a common shortcut is to bill everything under one generic code, and one code that gets wrongly cited for accounting work, 998213, is actually for legal documentation of intellectual-property rights, nothing to do with a CA's core services. Getting the SAC right on the invoice is a small discipline that keeps your own filings clean, which for a firm that files for everyone else is not a small thing.

Every unlogged hour is revenue you already spent the salary to produce.

The deadline tracker is not the whole practice

We have written before that a practice should run the practice, not just the returns. WIP is the other half of that idea. A deadline tracker tells you the GST return is due on the 20th; it does not tell you that the client attached to that return has three months of unbilled advisory sitting against their name. Both are the operating system of a firm, and both are the part the filing software leaves to your memory. The point is not to replace CompuTax or Winman. It is to run the business those tools serve.

What BizRevolt adds around your filing tools

BizRevolt is deliberately complementary. Keep filing where you file. What we add is the practice layer on top: an engagement per client with its agreed scope and fee, time and effort logged against it, WIP that is visible instead of imagined, and a one-click path from that WIP to a GST-correct invoice with the right SAC code. Deadlines, documents, roles for articles versus partners, and an audit trail sit in the same place, so the firm has one cockpit even though returns are still filed in the specialist tools.

An engagement per client, with scope and fee agreed up front so creep is visible.
Time and effort logged to a client, turning invisible WIP into a number you can bill.
One-click WIP-to-invoice with the correct SAC code and 18% GST.
A shared deadline board and document vault, with partner and article roles and a full audit trail.

A practice does not lose money on the returns it files. It loses money on the work it forgets to bill.

Filing software solved the returns years ago. The unglamorous problem that is left, knowing what you have earned and actually invoicing it, is the one that quietly decides a firm's margin. BizRevolt runs alongside your existing stack at Rs 1,499 for a Solo practitioner and Rs 4,999 for a Firm, and you can keep every filing tool you already trust.
