The problem every busy shop has
One phone sits at the counter, the owner is out, and a customer messages at lunchtime. Passing a single phone from hand to hand means missed messages and mix-ups. WhatsApp's Business app has a built-in answer: link more than one device to the same number.
What WhatsApp says you can do
WhatsApp's business resource page says the Business app supports up to 4 linked devices on a single number, so multiple team members can view and respond to messages from their own devices. Its blog describes the same idea: a phone can be linked as one of up to four additional devices, and for WhatsApp Business that means additional employees can answer customers from their own phones under the same account.
How linked devices behave
Per WhatsApp's blog, linked phones work like WhatsApp Web, tablets and desktops. Each device connects independently, and messages, media and calls stay end-to-end encrypted. One thing to know: if your main phone is inactive for a long period, all the linked devices are logged out. So keep the main phone with you, charged, and switched on regularly.
Where it stops
The resource page gives no limit on team members for the app itself, but it describes the four-device limit for one number. For more people or advanced features, it says to connect to the WhatsApp Business Platform, which it lists as including unlimited team members, and it also mentions a shared inbox on Meta Business Suite. One WhatsApp page also mentions up to 10 devices under its Meta Verified programme, so check what applies to your account before you plan around a number.
House rules we suggest
These are our advice, not WhatsApp rules.
- Decide who answers which kind of message, such as bookings, prices or complaints.
- Agree a hand-over: if you start a chat, finish it or tell the next person.
- Do not let staff share the main phone's screen lock or one login.
- When someone leaves, remove their linked device from your main phone the same day.
- Never promise a price or a slot that the owner has not approved.
When to move up
If several people answer all day, or you want a proper CRM, automatic reminders or an assistant that drafts replies for approval, the app on a few phones becomes limiting. That is the point to look at connecting your number to the Business Platform, as WhatsApp suggests, and at a front-desk tool built on top of it.
Write down who answers which type of WhatsApp message, then link each staff phone.
