A WhatsApp team inbox built for how support teams actually work
Move beyond one phone and one login. Give every agent visibility, add internal chat for handoffs, and organise conversations by department, without two people ever replying to the same customer.
How multiple people use one WhatsApp number as a team
The standard WhatsApp Business app is built for one person on one device (or up to four with limited Multi-Device support, but with no roles, no assignment, and no internal communication). The moment a second or third person needs to reply from the same number, you need a proper team layer on top of the WhatsApp Business API.
A WhatsApp team inbox gives every agent their own login into a shared workspace: they see the same conversations, but with roles, ownership, and a private space to coordinate that customers never see. For the mechanics of how conversations get assigned and routed once you’re set up this way, see our guide to the WhatsApp shared inbox. This page focuses on the team side: roles, internal chat, and department structure.
What your team gets
Individual logins & roles
Every agent gets their own login. Admins manage settings, billing, and routing; agents work the conversations assigned to them.
Internal team chat
A dedicated real-time chat, completely separate from customer conversations, with channels, @mentions, and file sharing.
Handoff notes
Leave context on a conversation before reassigning it. The next agent sees the full picture, no re-explaining from the customer.
Team inboxes by department
Create Sales, Support, or Billing inboxes and route the right conversations to the right group automatically.
Live conversation status
See who’s assigned, what’s unassigned, and what’s resolved in real time, so nothing gets a duplicate reply.
Full audit trail
Every assignment, note, and status change is logged, useful for coaching, coverage handovers, and accountability.
No more “who’s replying to this one?”
Without a team inbox, teams usually fall back on a shared phone, a spreadsheet, or a group chat to coordinate WhatsApp replies. It works until volume grows, then two agents answer the same message, a conversation sits untouched because everyone assumed someone else had it, or a handover between shifts loses context entirely.
A team inbox removes the guesswork: assignment is visible to everyone, unassigned conversations sit in a dedicated queue, and internal notes travel with the conversation, not in a separate chat app your customer support tool doesn’t know about.

Frequently asked
How many agents can share one WhatsApp Business number?
With the WhatsApp Business API connected through Resolvenyx, there’s no hard limit on agents like there is with the standard WhatsApp Business app. Starter includes 5 users, Growth 10, Business 20, and Enterprise 50, with extra users available as an add-on on any plan.
Can agents see what other agents are doing on WhatsApp?
Yes. Every agent sees the full conversation list with live status: who’s assigned, what’s unassigned, and what’s already been answered, so two agents never reply to the same customer by accident.
Is internal team chat separate from customer conversations?
Yes, completely. Resolvenyx includes a dedicated internal team chat with its own channels, @mentions, and file sharing, visible only to your team and never to customers.
Can I organise WhatsApp support by department?
Yes. You can create team inboxes such as Sales, Support, and Billing, and route conversations to the right one manually or with auto-routing rules based on keywords, tags, or time of day.
How do agents hand off a conversation to a teammate?
Reassign the conversation and leave an internal note with context, or ping the teammate directly in internal chat with an @mention. The next agent sees the full conversation history, so the customer never has to repeat themselves.
Do agents need separate logins?
Yes, each agent gets their own login with an Admin or Agent role. Admins manage settings, billing, and routing rules; agents work conversations within the inboxes they’re assigned to.
