In medicine, it is important to consider the context of communication with patients — you can't start from scratch every time. Our patients communicated through WhatsApp, Telegram, and Max, and the administrators couldn't keep up with all three applications at once. Because of this, some people could wait for a response for several hours, as their chat wasn't prioritized. We integrated WhatsApp and combined all client chats into our CRM. Now the senior administrator can track the context of communication, monitor service levels, and oversee upselling after appointments, which is very important for us. We contacted WhatsApp support once or twice, and they responded quickly.
