When conversations grow, a single phone cannot keep up, and each agent using their own number becomes a mess. See how to organize the whole team on the company's WhatsApp number.

Signs that your support needs organizing
- Customers complain that they sent a message and nobody replied.
- Two people reply to the same customer, each in a different way.
- Nobody can say how many conversations came in today or how long it took to reply.
- Each salesperson uses their own phone, and when they leave the company, the customers go with them.
- The company phone is passed from hand to hand or is tied to one computer.
All these problems have the same origin: WhatsApp was designed for one person, and the company is using it as if it were a support center.
Ways to use one number with several people
1. The WhatsApp Business app with linked devices
The free app lets you use the same number on a few linked devices, such as computers. It works for very small teams, but it does not distribute conversations, does not show who is handling what and does not produce reports. Everyone sees everything and nobody knows who owns each customer.
2. Unofficial tools
Programs that connect regular WhatsApp or WhatsApp Web to a dashboard. They seem to solve the problem, but they go against WhatsApp's terms of service and can get the number banned. See the details in Official or unofficial WhatsApp.
3. A support center built on the official API
The company's number is connected to Meta's official API, and conversations arrive on a platform where each agent signs in with their own user, on a computer or phone. This is the way built for teams: each conversation has an owner, managers follow everything and the history stays with the company.
How a WhatsApp support center works
- The customer sends a message to the company's official number, as always.
- A welcome menu asks about the subject: sales, support, billing.
- The conversation goes to the right team and is assigned to an available agent.
- The agent replies with text, files and quick replies. If needed, they transfer it to someone else without the customer repeating the story.
- The conversation is closed and may end with a satisfaction survey. The history is kept.
In HiperZap
- Teams and automatic distribution, with a welcome menu, business hours and a notice when the queue is slow.
- Transfers between agents and teams, with internal notes and @mentions of colleagues.
- Speed: company and personal quick replies, with attachments, scheduled messages, files, audio recording, quoting messages and reactions.
- Nothing forgotten: conversations waiting for a reply are highlighted, and an agent who closes the screen without notice is put on pause and their unanswered conversations go back to the queue.
- Supervision: supervisors see each agent's conversations, reassign them in bulk and track pause time.
- Management: support metrics, satisfaction surveys and automatic closing of idle conversations.
- On mobile: the dashboard works in the browser and can be installed as an app, with notifications.
The number of agents depends on the contracted setup. Discover multi-agent support.
How to set up the team
- Split by subject. Start with a few teams, such as sales and support, and create others only when needed.
- Define roles. Who configures (administrator), who oversees (supervisor) and who serves customers (agent).
- Agree on hours. Make it clear to customers when the team replies and what happens outside those hours.
- Create quick replies for the most frequent questions: hours, address, payment methods.
- Write a service standard: how to greet, how to introduce yourself and how to close.
What to track every week
- Time to first reply: what customers feel the most.
- Conversations per agent: shows whether the workload is balanced.
- Unanswered conversations: ideally close to zero.
- Satisfaction: the survey score and customer comments.
Support and campaigns on the same number
When the company sends campaigns on official WhatsApp or appointment reminders, customer replies arrive at the same support center. So plan your team for sending days, when the volume of conversations goes up.
FAQ about several agents on WhatsApp
Can I use the number my company already has?
Generally, yes: the number is connected to Meta's official API. How this affects using the number in the phone app depends on the case, and our team reviews it with you before connecting.
Do agents need a company phone?
No. Each agent signs in with their own user in a computer or phone browser. The company number is connected to the platform, not to a device.
Does the customer notice they are talking to different people?
They always talk to the same company number. When the conversation is transferred, the new agent sees the history and picks up where it left off.
