The Collaboration Gap

Social DMs were never built for teams. OnSync was.

Native apps make it impossible to track who said what or when a customer was last helped. We provide the missing layer of governance.

Stop sharing one phone

No more passing the office phone around or getting logged out of WhatsApp Web. Every agent gets their own secure login.

End 'Who's handling this?'

Automatic assignments and status labels (Open, Pending, Resolved) ensure every message has an owner and a next step.

Kill internal silos

Discuss complex tickets with internal notes the customer can't see. No more switching to Slack to talk about a WhatsApp chat.

Powerful Triage

Everything you need to resolve chats faster

From assignment rules to internal collaboration, our inbox is tuned for high-volume revenue and support teams.

Multi-Agent Access

Scale your customer service team. 5, 50, or 500 agents can handle messages simultaneously from one number.

Internal Collaboration

Use internal notes to brief teammates or @mention a manager to join a conversation without the customer knowing.

Global Search & History

Find any message across WhatsApp, Instagram, and Telegram in seconds. View the full history of every customer interaction.

Team Performance

Track KPIs like First Response Time (FRT), Resolution Rate, and Agent Workload with built-in reporting.

Role-Based Permissions

Control who can delete chats, export contacts, or send broadcasts with granular user roles.

Smart Notifications

Get alerted for new chats, mentions, or SLA breaches across Desktop, Mobile, and Web.

Implementation

FAQ

Common questions about Shared Inbox

Can multiple people use one WhatsApp number?
Yes. By using the official WhatsApp Business API through OnSync, your entire team can access the same number simultaneously from different devices.
Are messages synced in real-time?
Absolutely. When one agent replies, the message is instantly visible to all other agents and managers with access to that inbox.
Do customers see internal notes?
No. Internal notes are strictly for your team. They appear with a distinct yellow background in the inbox and are never sent to the customer.
