Quillix is the audit-automation suite built for CA firms managing GST clients. Invoice generation, statutory filing prep, Tally export — handled. So your team handles what actually needs a CA's brain.
Every month, the same week. Every client, the same scramble. If this sounds like your firm, you already know what we built Quillix for.
Every invoice your client raises for their own billing is already a GSTR-1 line by the time it's saved. You stop chasing data — because the data is already arriving, every day, from the people who have to enter it anyway.
No spreadsheets. No copy-paste between tools. No filing-day panic.
Set up your masters, raise invoices, export at month-end. Quillix doesn't try to be everything — it just handles GST + Tally, properly.
From the senior partner who oversees 50 clients down to the data-entry intern raising tomorrow's invoices — everyone sees only what they should.
Four upgrades landing on your dashboard over the next few quarters — pre-ordered for every Quillix firm.
Pay per firm, not per client store. Add unlimited stock items, customers, and invoices on every plan.
Try Quillix end-to-end on a single client store. No card, no time limit.
For firms running multiple GST clients with their own data-entry team.
We set up the store for you over a screen-share — masters, customer list, HSN codes, Tally export mapping. Online only, one session per store, paid once per store, never again. Skip it if your team prefers self-setup.
Try any paid plan risk-free — full refund within 30 days, no questions asked.
Workflow stuff that actually trips firms up — not whitepaper theory, not SEO fluff.
Wrong place of supply, B2CS rows that should be B2CL, HSN summary mismatches — what we see most often, why the offline utility flags them, and how to catch them before submission.
2A updates dynamically, 2B freezes monthly, and your books are whatever your client typed last night. Here's the priority order we follow and why it matters for ITC claims.
The turnover threshold has dropped four times since 2020. Updated slabs, who's exempt, the IRP/IRN flow, and what happens if you miss the cutoff date.
A focused 15-minute walkthrough — your workflow, your client kind of profile, live on a sample store.
Live demo on a sample client store. Your specific questions answered. No sales pitch.

Quillix is an audit-automation suite built specifically for Indian CA firms managing GST clients. It covers the full lifecycle: customer + stock masters, sales-invoice generation with auto CGST/SGST/IGST split, GSTR-1 filing preparation (B2B, B2CS, B2CL, HSN summary), and Tally-compatible exports.
The core idea: your clients raise invoices for their own billing, and that same data becomes your filing-ready GSTR-1 and Tally vouchers — no separate data collection step.
Indian CA firms, audit firms, and chartered accountants managing GST clients — from solo practitioners with 5 clients to mid-size firms running 100+ client books. Anyone whose monthly grind includes GSTR-1 prep, Tally voucher exports, and chasing client data on the 8th of every month.
We bill per firm, not per client. Three plans: Solo (₹999/mo, up to 5 client stores), Growing Firm (₹2,999/mo, up to 25 stores + early access to Sales OCR), and Enterprise (custom). Annual billing gets you 2 months free.
Full pricing breakdown is on the pricing section above.
30-day money-back guarantee, no questions asked. If Quillix doesn't save your firm time on the next filing cycle, drop us an email at support@quillix.co and we'll refund your subscription in full. No forms, no exit interview, no friction.
Yes. We provide Excel import templates for customer masters (with GSTIN), stock items (with HSN codes and GST rates), and ledger mappings (for Tally export). Drop in your existing client register and you're set up in minutes.
For Tally exports, we generate voucher-ready CSV files mapped to your Sales / CGST / SGST / IGST ledgers — drop straight into your books.
Yes. All data is encrypted in transit (256-bit SSL) and at rest. Each firm's data is fully isolated — your clients' invoices and GSTINs are visible only to your firm's users. We follow industry-standard practices for access control, audit logging, and backups.
Quillix is built on Google Firebase infrastructure, which is SOC 2 Type II and ISO 27001 certified.
Phased rollout over the next few quarters:
Sales OCR is next up (snap a paper invoice, AI extracts line items / GSTIN / HSN). Purchase OCR and 2A & 2B vs Books reconciliation follow after that. GSTR-3B filing rounds out the roadmap. We're being deliberately fuzzy on dates — we'd rather ship a feature when it's solid than commit to a quarter and slip.
Growing Firm and Enterprise plans get early access automatically. See the What's coming section for details.
Yes — a 15-minute live walkthrough with our team on a sample client store. We'll set up a profile that mirrors your kind of clients, show the GSTR-1 + Tally flow end-to-end, and answer your specific workflow questions. No sales pitch. Schedule it here.
Open your first client store, import a register, and raise a test invoice. If it doesn't save you time on filing day, don't switch. Simple as that.
