WhatsApp shared inbox: how a team works on one number

How a whole team answers from one WhatsApp number without passing a phone around: shared inbox, assignment, internal notes, tags and permissions.

Published: September 14, 2026 · 5 min read

The picture is familiar: one business phone passed from hand to hand, or WhatsApp Web open on three computers in the office. Two agents answer the same customer, another customer gets no answer at all, and nobody knows who promised what. This isn't a discipline problem. You simply can't run a team on a tool built for one person.

The fix is to connect the number to the WhatsApp Business API and work from a shared inbox. Here is how that works in practice, step by step, with examples from Whapiz.

Why WhatsApp Web on several computers isn't enough

The basics: one number, one shared inbox

Once the number is connected through Meta's platform (the Cloud API), every message arrives on the Tickets screen in Whapiz. Each agent signs in with their own user, from a computer or the mobile app, and customers keep writing to the same number and seeing the same business name.

The inbox has four fixed tabs: Open, Pending, Closed and All. A new conversation lands in Pending. An agent clicks "Accept", the conversation becomes theirs, and everyone can see it is being handled. That is how you stop two people from answering the same customer at the same time.

Assignment and transfers: every conversation has an owner

Tip: agree on a simple rule for who takes new conversations, by department, by shift or in rotation, and write it down. The system helps, but agreement within the team is what prevents duplicates.

Internal notes and team chat: what the customer doesn't see

In Contact Notes you write down what matters about the customer: what was agreed, what's missing, who to call back. Notes are saved on the contact and are never sent to the customer, so an agent who picks up the conversation on the next shift immediately knows where things stand. Keep notes short and factual: what the customer asked for, what was promised, and by when.

For quick questions between colleagues there is Internal Chat: one-to-one and group conversations, with files and voice notes, inside the system. It replaces the staff WhatsApp group, where customer screenshots, scheduling and personal matters all get mixed together.

Tags and custom tabs: order in a busy inbox

Colour tags mark a status or a topic, such as "Waiting for documents", "Quote sent" or "VIP". You can filter by them, and an admin or supervisor can turn them into extra tabs in the inbox. A tab like this works as a stage in a process: the "Move to…" button moves the conversation to another tab, and every tab has a counter that updates live.

Permissions: everyone sees what they need

User (agent)Their own conversations, plus unassigned conversations in their departmentsReplies, transfers, tags and writes notes

The number of users and departments depends on your plan.

Quick responses: the same quality from every agent

In the message box you type "/" and pick a saved answer: opening hours, an explanation of a process, directions. You keep the wording on the Quick Responses screen, and in the settings you decide whether each agent has a personal list or the whole business shares one. Approved WhatsApp templates appear in the same list. Start with the answers your team types most often, and word them well, once.

What the manager sees

On the Dashboard, admins see how many conversations came in, how many are open and how many are waiting right now, the average handling time and the average waiting time, and a table per agent: open conversations, closed conversations and who is online. You can filter by department, by connection and by agent.

A day in a shared inbox

In the morning, a supervisor opens the Pending tab and sees what came in overnight. The menu bot has already asked each customer what it's about, so the enquiries are waiting in the right departments. Agents click "Accept" and start replying, each in their own department. A customer with a technical question is transferred to support, with two lines in Contact Notes. An agent heading out to a client meeting keeps replying from the mobile app. At the end of the day everyone closes the conversations that are done, and the manager sees on the Dashboard how many enquiries came in, how long customers waited and who handled what.

5 rules for a team on one WhatsApp number

  1. Accept a conversation before you reply, so everyone knows it's being handled.
  2. Transfer with a note: two lines in Contact Notes save the customer from explaining everything again.
  3. Close conversations that are done, so the Open tab reflects real work.
  4. Agree on a few clear tags rather than many tags nobody remembers.
  5. Watch the 24-hour window: a customer who has waited more than a day can only be contacted with an approved template.

Frequently asked questions

Can all agents answer from the same number at the same time?

Yes. The number is connected once, and each agent works with their own user. The customer sees the business name, not the agent's phone.

Does the customer see which agent replied?

Only if you want them to. The "Sign" switch in the message box adds the agent's name at the top of the message. When it's off, the message goes out without the agent's name.

What happens when an employee leaves?

An admin removes the user, and their access to the system ends. The conversations and history stay with the business, because they were never on that person's phone.

Can I connect more than one WhatsApp number?

Yes. You can connect several numbers, for example one for sales and one for service, and all conversations arrive in the same inbox. The number of connections depends on your plan.
