WhatsApp for CA firms, tax consultants and finance services

What goes wrong in a practice today

In most small firms, WhatsApp already is the client channel. It is just running on one person’s phone with no system behind it.

• The partner’s phone is the CRM. Hundreds of unread chats, clients mixed with family groups, and no way for a junior to pick up a thread when the partner is in a client meeting.
• New enquiries wait. A GST registration enquiry from a Google ad sits in an office inbox for two days. The business owner has already signed up with the firm that called back that afternoon.
• Documents are chased one message at a time. Someone types the same “please send your bank statements and Form 16” message to each client, then tracks who replied in a spreadsheet.
• Everything arrives in the last week. Clients were never reminded early, so the deadline rush lands on the same few days every time.
• Loan and insurance leads eat the day. A loan broker’s Meta campaign brings a stack of leads, many of them not eligible, and the team spends hours calling to find out.
• History is scattered. One client’s story is split across a partner’s WhatsApp, an assistant’s email and last year’s Excel file.

How DueDoor handles an enquiry, from first message to engagement

DueDoor runs your official business number on the WhatsApp Business API, with a shared team inbox, an AI agent, AI calling and a pipeline in one workspace.

1. The enquiry lands in one pipeline. Google Ads and Meta lead forms, website forms and WhatsApp messages come into one place. Duplicate-safe phone matching means an existing client who enquires about a new service stays on the same record.
2. The AI asks your qualifying questions. The WhatsApp AI agent answers from your service list, fee ranges and document checklists, then asks what you would ask: which service, type of entity, rough turnover, current accountant, city. It works in English and Hindi.
3. Loan and insurance leads get an AI call. The AI voice agent calls and runs your eligibility script. The recording, transcript, summary and outcome are saved on the lead.
4. The right person owns it. An automation assigns the lead by service (tax, audit, bookkeeping, loans, insurance), notifies them and creates a task.
5. A consultation is booked. The client picks a slot from a booking link and gets a WhatsApp confirmation and a reminder before the call.
6. Once engaged, the client keeps one history. Every message, call, note, task and stage change sits on the same record, visible to whoever is handling the file today.

Automations for firms and brokers

Care with financial data

Clients trust you with PAN, Aadhaar, bank statements and income details. The principle DueDoor is built on is that automation should carry reminders and conversations, not sensitive data.

• Never put sensitive details in a broadcast or template. No PAN, account numbers, amounts due or tax figures. A reminder says a deadline is coming; the details stay in the one-to-one conversation or your own systems.
• Decide how documents are submitted. Some firms accept documents on WhatsApp, others prefer their own portal or email. Put your policy in the checklist message so clients do not guess.
• Keep client files out of the AI. The knowledge base is for service descriptions, fee ranges and checklists, not client records.
• Restrict access by role. Roles and access control decide which staff see which conversations, and the audit log records every action.
• Broadcast only to opted-in clients. CA firms should also check their professional body’s guidance on solicitation before any outbound campaign to people who are not already clients.

What to set up first

• Write your service list with fee ranges and a document checklist per service.
• Write the qualifying questions for each service line, and a separate call script for loans or insurance.
• Decide who owns which service, and set roles before inviting staff.
• Get templates approved: enquiry reply, document checklist, document reminder, deadline reminder.
• Build an opted-in client list, split by service, before the next filing deadline.
