Client messaging and calls for CA firms and tax consultants
Collect documents before each GST, TDS and ITR deadline, follow up on fees and keep the office phone manageable during filing season.
Which channels should a CA firm use to communicate with clients?
Most CA and tax practices do best with WhatsApp for document checklists, uploads and fee reminders, SMS for short deadline alerts that reach every client, AI Voice calls to chase clients who have not sent papers before a due date, and a simple IVR during ITR season. Promotion is limited, because ICAI rules restrict advertising by chartered accountants.

Questions about messaging for CA firms and tax consultants
Is WhatsApp safe for collecting client documents such as bank statements?
It is reasonable with sensible controls. Through the Business API, files reach your firm's system rather than a staff member's personal phone. Limit inbox access to the team handling each client, delete files you no longer need under your retention policy, and tell clients what you collect and why, as the DPDP Act expects.
Can a CA firm send SMS reminders before GST and ITR due dates?
Yes. Register the firm on a DLT platform, get a sender header approved and register reminder templates with variables for the return name and due date. Reminders to existing clients about their own filings are service messages, so DND preferences do not block them the way they block promotional SMS.
Are chartered accountants allowed to send promotional messages?
Be careful here. ICAI's code of ethics restricts chartered accountants from soliciting clients or advertising beyond what its guidelines permit, so bulk promotional SMS or cold calls are best avoided; check ICAI's current guidance. Messages to existing clients about their filings, deadlines and fees are routine practice.
Will the AI calling agent give tax advice to clients?
No. The agent is set up to remind, collect and record, not to advise. If a client asks whether a deduction applies or how to reply to a notice, it promises a callback from the CA or the article handling the file and logs the question for them.
Can reminders be triggered from our practice software or Tally?
Yes, if the software can call an API or receive a webhook, and MsgClub also has an SMS plugin for Tally. Many smaller practices keep a client list in Google Sheets with return types and due dates, and use Zapier to send the right reminder on the right day.
What does a small CA practice need to get started?
A MsgClub account, a WhatsApp Business API number, two or three approved templates such as the monthly checklist and fee reminder, and a client list with mobile numbers. DLT registration for SMS can take some time, so begin it well before the next filing season.
