# Simplifying Role-Based Access in Mercuri: Use Cases and Solutions

Mercuri allows businesses to manage user access with **fine-grained permissions**, giving you full control over who can view or take action across different parts of the platform. 

Whether you’re managing a small team or scaling across multiple locations, this flexibility ensures that the right people have access to the right tools.

### Use Case 1: Managing Access Across Multiple WhatsApp Numbers

Let’s say your business uses **multiple WhatsApp numbers,** one for sales and another for support. Naturally, you want only the sales team to access the sales inbox, and support agents to access customer support chats.&#x20;

Granting full access to all inboxes would create confusion, potential data leaks, and miscommunication.

#### How to Assign Granular Permissions

To implement this setup:

1. **Go to**: `Settings > Teams`
2. **Click**: `Add User`
3. **Fill in** the new user's details (name, email, role, etc.)
4. Under the **Permissions** section:
   * Locate the **Conversations** dropdown
   * Select the specific **WhatsApp number** this user should access
   * Choose **“Assign Agent”** to allow them to manage chats for that number

You can repeat this process for each team member, ensuring clean access control for multi-channel operations.
