CRM for WhatsApp Business

Software that links your business’s WhatsApp with your customers and your calendar: messages go out from your number, conversations arrive in an inbox your team shares and each one is kept in the customer’s record. With Kairox, appointment notifications also go out on their own and, on the Advanced and Intelligent plans, an AI receptionist replies and books appointments.

Yes. You connect your number from the dashboard, through Meta’s official sign-up, and keep using the WhatsApp Business app on your phone (version 2.24.17 or later). What you write from the app is also saved in the CRM and, if you have the AI receptionist, it steps back from that conversation for 12 hours. When you connect it, Meta turns off broadcast lists, disappearing messages, “view once” and live location in the app. If you use regular WhatsApp on that number, you first need to switch it to WhatsApp Business.

No. Appointment notifications, campaigns and the inbox come with all three plans, Essential included, and your team replies from the dashboard. The AI receptionist, on Advanced and Intelligent, replies straight away, understands voice notes and books, changes and cancels appointments in your calendar.

The confirmation when booking, a reminder before the appointment (24 or 48 hours before, or none), the notice if the appointment changes or is cancelled, the review request after the visit, the message to whoever is on the waiting list when a slot frees up and the one about the last session of a pack. For vets, vaccinations that are due as well. Only to customers who have agreed to receive them.

Meta charges for each message delivered, according to its category: marketing, such as campaigns; utility, such as confirmations and reminders; and authentication. Replies to a customer who has written to you are service messages: since 1 October 2026, each number gets 1,000 free a month and Meta charges for any beyond that. What you send from the WhatsApp Business app is still free.

Meta bills it separately, at its current rates, and Kairox adds no mark-up. For this, your WhatsApp Business account needs a payment method.

Yes, to those who have agreed to receive promotions: to a group, to people who haven’t been in for a while or to everyone. Never to anyone who has unsubscribed or who has received another campaign in the last 7 days. Before you send it, the dashboard tells you how many customers it will reach and what it will cost in Meta charges.

Replying BAJA or STOP is enough to stop all automatic messages. To drop only the promotions, the customer replies “no promociones” and keeps getting the notifications about their appointments.

A Meta rule: when a customer writes to you, you can reply with free-form messages for the next 24 hours. After that, you can only write to them with a template approved by Meta, and the inbox offers you one with “Resume the conversation”.
