Multi-agent WhatsApp, one number

A WhatsApp shared inbox your whole team can work

One WhatsApp Business number, every agent working it at once — with assignment, internal notes, and a full history on every contact. No more passing a phone around the office, and no more two people replying to the same customer.

The WhatsApp Business app was built for one person

The free WhatsApp Business app assumes a single owner on a single phone. The moment you have two people answering customers, it starts to cost you money — and you usually find out from an annoyed customer rather than a report.

  • Only one device can be properly logged in, so the number lives on someone's personal phone — and leaves with them when they do.
  • Two agents answer the same message with different information, and the customer stops trusting either answer.
  • Nobody can tell which conversations have been handled, so genuine buyers sit unanswered overnight while resolved chats get chased.
  • When an agent leaves, their conversation history and context walk out the door with them.
  • There is no way to measure who is responding, how fast, or which conversations turned into revenue.

What you get

One number, unlimited agents

Every agent gets their own login against the same WhatsApp Business number. Conversations arrive in a single stream that the whole team sees in real time — no shared passwords, no borrowed phones.

Assignment and ownership

Assign a conversation to a specific agent so ownership is never ambiguous. Assigned chats can be filtered out of everyone else's view, which is what actually stops double-replies.

Internal notes the customer never sees

Leave context on a conversation for whoever picks it up next — what was quoted, what was promised, what to avoid. Notes stay inside ChatSathi and are never sent to WhatsApp.

Filters, tags and saved views

Slice the inbox by assignee, tag, status, or custom field. Tag a conversation once and it follows the contact, so segmentation for later broadcasts is a by-product of doing support.

Response-time visibility

See first-response and resolution times per agent, so slow queues surface as data rather than as complaints. SLA rules can flag conversations that have been waiting too long.

Full searchable history

Every message on a number is stored against the contact, searchable long after the agent who sent it has moved on. New agents get instant context instead of asking the customer to repeat themselves.

How it works

  1. 1

    Connect your WhatsApp Business number

    We run the Meta Cloud API setup with you in a guided session — connecting the number, verifying the business, and getting your first message template approved. You keep ownership of the WhatsApp Business Account throughout.

  2. 2

    Invite your team and set roles

    Add agents with role-based permissions — owner, admin, agent or viewer. Agents see and work conversations; viewers can read without replying, which is useful for training and for managers who only need oversight.

  3. 3

    Decide how conversations get assigned

    Let agents claim conversations from the shared queue, or set routing rules that assign automatically based on tags, keywords or the customer's history. Either way, every chat has exactly one owner.

  4. 4

    Work the queue and measure it

    Agents reply, add notes, tag contacts and close conversations. Response times, volumes and per-agent activity roll up into reports, so you can see where the queue is actually backing up.

Frequently asked questions

Can multiple people use one WhatsApp Business number at the same time?

Not with the free WhatsApp Business app, which is limited to one primary device. It becomes possible through the official WhatsApp Cloud API, which is what ChatSathi is built on. Once your number is connected to the Cloud API, every agent logs into ChatSathi with their own account and works the same number simultaneously, with assignment to prevent overlap.

Will my customers see that several different agents are replying?

No. Every message goes out from your single business name and profile, so from the customer's side it is one continuous conversation with your business. Agent identity and internal notes stay inside ChatSathi.

Do I lose my existing chat history when I connect to the Cloud API?

Message history that lives on the phone in the WhatsApp Business app does not transfer to the Cloud API — that is a Meta platform limitation, not a ChatSathi one. Your contacts and the number itself carry over, and every conversation from the moment you connect is stored and searchable in ChatSathi. If history matters to you, we will walk through it during onboarding before you migrate.

How does the inbox stop two agents replying to the same customer?

Two ways. Conversations can be assigned to a single owner and filtered out of other agents' views, and the inbox updates in real time so an agent can see when a chat is already being handled. For teams that want it strict, routing rules can auto-assign every incoming conversation so nothing ever sits unowned.

Is there a limit on how many agents I can add?

Agent seats are set by your plan — the limit for each plan is listed on the pricing page. Higher tiers also support multiple WhatsApp numbers in one workspace, which is what multi-brand and multi-location businesses usually need.

Can I restrict what an agent is allowed to see or do?

Yes. ChatSathi uses four roles in ascending order of privilege: viewer, agent, admin and owner. Viewers can read but not send. Agents work conversations and contacts. Admins configure automations, templates and team settings. Owners control billing and can transfer ownership.
