My practice runs on WhatsApp. Not partly. Not as a convenience layer on top of email. Clients message me on WhatsApp, send documents on WhatsApp, approve filings on WhatsApp, and that is where the record of the engagement lives.

This was not a marketing decision. It was a decision about where my clients already were.

The email fiction

For years I did what every professional firm does. Formal email, documents as attachments, a portal with a login nobody could find, and a phone number for the times email failed. The portal was the clearest lesson. We built it, explained it, sent credentials, followed up twice. Adoption was dismal. The same clients who would not log into a portal would answer a WhatsApp message in four minutes.

The turning point for me was noticing how much of my week went into chasing rather than working. Asking for a bank statement. Asking again. Explaining which bank statement. Receiving the wrong month. That loop is not a tax problem, it is a communication problem, and it was eating the part of my day that clients actually pay for.

What changed in practice

Moving to WhatsApp changed three things immediately.

  • Response time collapsed. Questions that used to take two days of email round-trips now close in an afternoon
  • Documents started arriving. Clients photograph a challan or forward a bank PDF without thinking about it. The friction of “find the file, open email, attach, send” is what was stopping them
  • The context stayed in one place. One thread per client, searchable, in date order, with the documents inline

The last point is underrated. When a query comes up eighteen months later, I scroll one thread. I am not reconstructing a decision from three email chains, a phone call nobody minuted, and a file note.

Why it works in India specifically

WhatsApp is not an app here, it is the default surface for communication. Business owners run supplier negotiations, staff coordination and customer service through it. Asking them to step outside that for their CA is asking them to do something unnatural.

There is also a status dimension people underestimate. Email feels institutional. A WhatsApp message from the person who actually does your work feels like access. For an owner-run business, access to the professional is most of what they are buying.

It travels well too. Roughly half my work is with NRIs and foreign-owned entities. WhatsApp works the same from Dubai, Singapore or New Jersey, with no international call charges and no time-zone dance about who picks up the phone.

The discipline it demands

None of this works without rules, and the rules are where most firms get it wrong.

The first is that informal channel does not mean informal record. Anything that constitutes advice, an approval or an instruction gets restated clearly in the thread, so the position is unambiguous when read cold a year later. If a client says “go ahead”, I write back what exactly they have approved.

The second is that sensitive credentials do not live in chat. Portal passwords and banking details go through a separate channel. A chat history is convenient precisely because it is complete, and that is also its risk.

The third is boundaries. An always-open channel becomes an always-on expectation unless you manage it. I answer quickly during working hours and I am comfortable not answering at eleven at night. Clients adjust to whatever you demonstrate.

The fourth is structure behind the scenes. WhatsApp is the client-facing surface, not the filing system. Documents are pulled out, named, and stored properly. The chat is the conversation; it is not the archive of record.

What I would not claim

This is not a fit for every practice. Large-team firms with several people touching one client need shared inboxes and case management, and a personal WhatsApp thread does not scale that way. Heavily regulated engagements may have retention requirements that a consumer messaging app does not satisfy cleanly.

My practice is deliberately built so the client talks to the person doing the work. WhatsApp fits that shape. If your firm is built differently, copying the channel without copying the operating model will just make you harder to reach.

The broader point

Professionals spend a lot of energy designing processes that are convenient for the firm and then trying to persuade clients to adopt them. The better order is the opposite. Find where clients already are, meet them there, and put your discipline behind the scenes where it belongs.

For firm-level engagements — audit, transfer pricing, cross-border structuring — the work runs through AeTx, and even there the front door is a message rather than a form. If that is how you would rather work with your accountant, say hello.
