One WhatsApp number, your whole team, no shared phone
The WhatsApp Business app assumes one number belongs to one person. Businesses grow out of that fast, and the usual workaround is a phone on a desk that everybody reaches for. It works until two people reply to the same customer differently.
What breaks at scale
Two people answering the same chat is the visible failure. The quieter ones are worse: conversations nobody claimed, promises nobody recorded, and no way to see who is carrying the load.
There is also a security problem nobody enjoys discussing. A shared phone means shared access to every customer conversation, and no record of who read what.
How a shared inbox works
On the official Business API, one number can be worked by many agents at once. Conversations are assigned, either manually or by rule, and each one has a clear owner.
Internal notes let your team talk about a conversation without the customer seeing it, and the full history stays with the contact rather than with an employee.
- Assign conversations by team, skill or round-robin
- Internal notes and mentions, invisible to the customer
- Full history retained when someone leaves
- Response-time and volume reporting per agent

AI on the first reply
The highest-value use of a shared inbox is to keep most conversations out of it. An AI agent takes the first reply, resolves what it can, and only assigns a human when the conversation actually needs one.
Your team then spends its time on the conversations where a person changes the outcome, rather than on order-status questions.
Frequently asked questions
How many people can use one number?
As many as you need. The official API is built for multiple concurrent agents, unlike the Business app which is tied to a single device.
Can we keep our existing number?
Yes, provided it is not currently active on the consumer WhatsApp app. Migrating deregisters it there, which removes that device's chat history.
What happens to conversations when someone leaves?
They stay. History belongs to the business and lives against the contact record, not on an individual's phone.
