CA_CS Tool: the multi-country compliance OS for CA and CS firms.
CA_CS Tool is practice-management and compliance software for chartered accountant and company secretary firms. Each firm gets its own tenant and subdomain; each client gets an auto-generated filing calendar for its country (India, Singapore, UAE or Malaysia), WhatsApp reminders, proof uploads, OCR for invoices and bank statements, and a jurisdiction-aware AI assistant.
A closer look: from a scanned document to a tracked filing.
Built around the filing calendars of India, Singapore, UAE and Malaysia — each client gets its own country's forms, due dates, currency and regulators — with the messy realities of running a practice already accounted for. Multi-tenant. WhatsApp-native. Owner-facing.
From client onboarding to audit-ready trail — in one workflow.
Onboard the client
Pick entity type, applicability flags (GST/TDS/PF/ESI/Audit), tag the CA staff. Done in 90 seconds.
Calendar auto-generates
47 filings for FY 25-26 land in their compliance tab — GSTR-1/3B/9, TDS 24Q/26Q/27Q, AOC-4, MGT-7, ITR, PF, ESI.
Nudge on WhatsApp
Owner gets a WhatsApp ping 7 days before each due date — and a follow-up the morning of. CA staff sees the thread.
File with proof
Drop the ARN/challan reference, drag-drop multiple acknowledgements, mark filed. Status flips green, owner notified.
Permanent audit trail
Reference numbers + acknowledgements live in the company vault. Year-end audit pulls a single ZIP per client.
Four jurisdictions, one platform
Each tenant is set up for one country. India gets GST/TDS/MCA/ITR/audit; Singapore gets GST F5, ACRA AR, Corp Tax, CPF, IR8A, S45 WHT, RORC, Foreign Worker Levy, IR21, PDPA; UAE gets VAT, Corporate Tax, ESR, trade licence; Malaysia gets SST, LHDN, SSM, EPF/SOCSO, MyInvois.
Country-aware compliance auto-pilot
Onboard a client in two minutes; the calendar fills itself against that client's own country's filing schedule — the right forms, the right due dates, the right regulators. Per entity type, per country.
Multi-tenant by design
Every firm gets its own subdomain and isolated client base. The platform admin (you) sees revenue and tenants; tenants only ever see their own clients. Country is fixed per tenant, enforced server-side.
WhatsApp-first client comms
Send filing reminders, document requests and country-specific payment links to clients on WhatsApp Cloud API — with click-to-send fallback. Every thread is logged against the client.
Proof you can audit
Mark a filing filed with its reference number, drag-drop multiple acknowledgements, and the trail is permanent. Document vault with expiry alerts for licences, certificates and registrations.
OCR for invoices & bank statements
Drop a PDF invoice or a 40-page bank statement. The tool extracts taxable, tax and totals, or reconciles entries against monthly data — Tesseract under the hood, server-side.
Jurisdiction-aware AI assistant
Plain-English explainers for any filing, an AI "improve" button on engagement letters that knows the client's jurisdiction, and a weekly partner plan across all clients. Powered by Alpha AI.
Roles that match how firms work
Tenant admin (firm partner), staff (team — sees every client), editor (business owner — edits their company), viewer (auditor — read-only). Per-company memberships, not all-or-nothing.
Practice management included
Tasks, timesheet and firm calendar across all clients. Currency- and format-aware (₹ / S$ / AED / RM). Reports approval workflow for owner → CA sign-off.
A 30-minute guided walkthrough, in your country’s calendar.
We onboard one of your clients live: entity type, applicability flags, the auto-generated calendar, a WhatsApp reminder and a filing marked with proof. Seeded tenants exist for India, Singapore, UAE and Malaysia.
How is CA_CS Tool priced?
CA_CS Tool uses the same three components as every EntropyX product: a product licence, a one-time setup for integration, and an optional support plan. Prices are not listed because setup depends on your stack and the licence on your scale; a written quote arrives within one business day of a scoping call.
Small practices start on a flat monthly plan priced by number of clients and staff seats.
Licence
A subscription or annual licence. Self-hosted licences cover the software and updates; managed cloud adds hosting, monitoring and backups.
Setup and integration
A one-time, fixed-scope project scoped in writing after discovery: connecting WhatsApp Cloud API, MCA21 lookup, Email, Accounting exports, plus data migration where needed. Typical time to live: firm live in one week.
Support
Standard support in business hours (08:00–22:00 IST, Monday to Saturday) is included. Priority support adds a named engineer, response targets by severity and scheduled reviews.
What moves the number
Users, accounts or clients on the product; self-hosted versus managed cloud; the integrations you need; jurisdictions or chains to cover; the support level. Bundles with EntropyX Chat, EntropyX Tickets, Web Development share one setup and are priced together. Monthly subscriptions carry no long-term commitment; annual licences are discounted; invoicing in USD or INR.
