Built from inside the filing room.

Why we exist

Walk into any mid-sized CA firm on the 8th of the month and you'll see the same picture: three monitors open, two of them are Excel, one is Tally, and someone is on the phone with a client asking for "the sales register, but cleaner this time." The actual filing (the GSTR-1 push, the Tally voucher export, the reconciliation against 2B) gets done in a panic between 6pm on the 10th and midnight on the 11th. Every month. For every client.

That work is not difficult. It is repetitive, mechanical, and unforgiving of small mistakes. A wrong state code costs a B2CS row that should have been B2CL. A missed RCM entry costs an interest notice three quarters later. A Tally voucher entered twice costs an hour of triangulation.

None of this is what a CA firm pays a professional to do. It is what a CA firm pays a professional to supervise. Quillix exists to take the supervision part and turn it into one screen, so the senior gets back the time they were spending checking other people's Excel.

What we believe

Three things shape every product decision we make:

• The data already exists. If your client raises an invoice, that invoice is the GSTR-1 row. Re-typing it into a sales register is theft of your time. Quillix's billing entry becomes the filing entry. No copying, no spreadsheets in between.
• The output is the test. Software for CA firms gets judged on one thing: whether the GSTR-1 JSON validates on the GSTN portal first time, every time. Not the dashboard. Not the charts. The JSON. We optimise everything backwards from there.
• Trust is built on Tally. Every Indian audit firm has a decade of muscle memory in Tally. We don't try to replace it. We export to it, cleanly, every time. Your team keeps the workflow they know.

Who we are

Quillix is a partnership between a founder studying for the CA Final and a practising CA firm in Chennai. The founder watched the firm's monthly GSTR-1 grind across two full filing cycles before writing a single line of product code. Every design choice in Quillix traces back to something we saw happen on that firm's desks at 11pm on the 10th.

The partnership runs both ways. The firm pressure-tests every piece of accounting and compliance logic before it reaches another firm's books: voucher entries, GSTR-1 JSON shapes, RCM scenarios, B2CL threshold edge cases. The product team writes the software around how the firm works, not how a textbook says GST should work. If a feature can't survive a real filing day on the partner firm's clients, it doesn't ship.

We're independent and bootstrapped. No investor pressure, no quarterly growth theatre, no scope creep into adjacent markets we don't understand. We name partner firms in our case studies when they give consent. And we'll be straightforward about where the credentials sit: the CA Final is in progress, the practice partnership is live, and the audit-room hours are not theoretical.

How we work

A few principles we hold ourselves to:

• No fake urgency. No "limited-time offer" banners. The price you see is the price for as long as the page is live.
• No dark patterns. Cancel from inside the app, no email-to-retain flow, no "are you sure" loops.
• No roadmap dates we can't hit. Features are listed as "in active development" or "on the roadmap"; never with a quarter attached unless we are certain we will ship inside that window.
• 30-day refund. If Quillix doesn't fit your firm, we refund. No forms, no questions.
• Your data stays yours. Export anything you've entered at any time: CSV, XML, GSTR-1 JSON, Tally voucher. If you cancel, we delete. Full policy here.

Where we're going

The current product covers both sides of a CA firm's GST cycle: customer and stock masters, invoice generation, purchase, payment, receipt and journal vouchers, GSTR-1 prep, 2A/2B reconciliation, GSTR-3B prep and a direct Tally integration, plus AI-powered Sales and Purchase OCR that turns a photo of a paper invoice or supplier bill into a booked entry. Next, in this order: pushing returns, e-invoices and e-way bills straight to the government portals; then financial statements (trial balance, P&L and balance sheet); then income tax, TDS and audit documents.

None of that timeline is a promise. It's the order we're working in. If a CA firm tells us a different workflow is bleeding them more, we listen.
