Questions about WhatsApp Business API for CA firms and tax consultants

Can a CA firm send promotional WhatsApp messages?

Generally not. ICAI's code of ethics restricts members from soliciting clients and limits advertising, so a broadcast offering tax filing services to strangers is risky. Keep the firm number for existing clients: data requests, due date reminders, acknowledgements and invoices. Firms that are not ICAI members follow their own professional rules.

Is it safe to collect Form 16 and bank statements on WhatsApp?

WhatsApp messages are encrypted in transit, and with the team inbox the files stay on the firm's number rather than a staff phone. Limit inbox access by role, download files to your secure storage, and under the DPDP Act keep client data only as long as you need it.

Can clients send Tally or Excel files on WhatsApp?

Yes. WhatsApp accepts documents such as Excel, PDF and zipped exports up to the size limit Meta sets for documents. Very large ledgers are better shared through your cloud folder, with the link sent in the chat.

Do GST and ITR reminders count as utility messages?

Usually yes, when they relate to the client's own registration and an upcoming filing, because they are account updates. If a reminder also promotes a new service, such as trademark registration, Meta will classify it as marketing.

Can partners and articles all reply from one firm number?

Yes. MsgClub's team inbox lets every staff member log in, with clients assigned to a partner or desk. Internal notes record instructions such as 'client wants old regime', and the whole history stays with the firm when someone leaves.

Should we send acknowledgements by email or WhatsApp?

Both work, but clients open WhatsApp faster and can forward the ITR-V to their bank for a loan in a tap. Many firms send the PDF on WhatsApp and keep email for formal engagement letters, audit reports and anything that needs a digital signature trail.
