WhatsApp Business for multiple users: how a team can share one number

It usually starts with one phone at the front desk. Then a second salesperson joins, then someone covers evenings, and suddenly three people are replying from one WhatsApp number with no idea who promised what. Here are your real options for running one number as a team.

Option 1: Linked devices on the free Business app

The WhatsApp Business app lets you use one number on:

• The main phone, plus
• Up to four linked devices: WhatsApp Web, the desktop app, or another phone.

Some paid Meta Verified plans allow more linked devices. Set it up from Settings → Linked devices → Link a device on the main phone.

What works: two to five people can read and reply from different screens, for free.

What doesn’t:

• Everyone sees everything. No assigning a chat to one person.
• No record of who replied. Every message looks like it came from “the business”.
• Two people reply to the same lead or, worse, nobody does, because each assumes the other will.
• No roles or permissions. A new hire can see and delete every chat.
• No reporting on response times or results per person.
• No real automation beyond a greeting and away message.

Linked devices were built for one person using several screens, not for a team.

Option 2: A team inbox on the WhatsApp Business API

Connect the number to the official WhatsApp Business Platform through a provider or CRM. Then:

• Unlimited users (depending on your plan), each with their own login.
• Chats assigned to a person, automatically (round-robin) or by hand.
• Internal notes and history on every contact.
• See who replied and when.
• Automation: instant first replies, follow-ups and reminders.
• Reports on response time, calls, wins and leads by source.

The trade-off: Meta charges for template messages you send to start conversations (incoming messages and replies within 24 hours are much cheaper or free), and you need a Meta business portfolio. Details: WhatsApp Business app vs API and API pricing in India.

How to set up a team on one number (the practical way)

1. Decide who owns what. New enquiries round-robin? By product? By city?
2. Move to an API team inbox if more than two people reply or you need follow-ups to run on their own.
3. Check coexistence if you want to keep the Business app on the owner’s phone.
4. Write your business facts once (prices, timings, policies) so everyone, and any AI, answers the same way.
5. Set a response time target, for example under 5 minutes in working hours. See speed to lead.
6. Use a daily call list so each person knows who to call first.
7. Review weekly: missed chats, slow replies, leads with no next step.

How OakDeal runs a team on one number

OakDeal connects your WhatsApp number through Meta’s official platform and gives every teammate their own login. New leads are shared out in turn, the AI sends the first reply in seconds, and any teammate can take over a chat with one tap, which stops the AI in that chat. Each person gets a Today list of who to call, and you can see calls, demos and wins per person.
