WhatsApp is not a CRM.

A lot of businesses run on WhatsApp in the early years. A shared number, a group for staff, pinned chats with regulars. Everyone has the app, it's fast, and it costs nothing. For a while that's enough.

The problems usually start when the business grows past the point where one or two people can hold the full picture in their heads.

We've worked with three clients who went through a version of this. Two of them had been running on WhatsApp: a chain of pilates studios and a real estate agency. The third, a credit provider, had been running on paper and phone calls, which is the same pattern one step earlier. In each case, the change wasn't triggered by one bad incident. It was the sum of smaller ones.

What tends to go wrong

• Messages get buried before anyone reads them. The client re-sends, staff apologise, and the interaction costs more than it should have.
• Two people reply to the same client with different answers, because neither saw the other's reply.
• A booking, a confirmation, a payment, and a reschedule end up in four separate threads. Reconstructing the current state means scrolling through all of them.
• The person who carries the context of every active case is unavailable for a day, and the rest of the team can't answer basic questions about who is waiting for what.

What WhatsApp is good at

WhatsApp is a good messaging app. It's built for informal, 1-to-1 conversation, and it's very good at that. What it doesn't do is distinguish between a question, a booking, a complaint, and a payment confirmation. Everything is a message in a thread.

Those distinctions matter to a business. A system that logs a booking separately from a complaint, routes them differently, reminds someone to follow up, and knows when a case is closed is doing work that a chat client isn't designed to do.

When the threshold is crossed

There isn't a fixed point where WhatsApp becomes insufficient. There are signals that the business is already past it:

• More than one person needs to know the status of every client.
• A missed message translates into lost revenue.
• Staff spend noticeable time searching chats.
• A basic question like "how many deals are currently open" can't be answered without scrolling.

When several of those apply, the business has outgrown chat as a system of record. The main variable is how long the transition is put off.

What we built for clients

For the pilates studios, a booking platform. Classes, schedules, payments, and white-label options per studio. WhatsApp stayed, but as a channel for questions rather than as the system running the business.

For the real estate agency, a CRM with lead capture, follow-up reminders, and property presentations. The agents kept talking to clients on WhatsApp and stopped tracking them there.
