Callidus Works vs. Trengo

Trengo is a Dutch omnichannel customer service platform. It bundles all communication channels — email, WhatsApp, Instagram, Facebook Messenger, live chat, and SMS — into one team inbox. With AI Agents and AI Journeys, Trengo automates frequently asked customer questions. The platform is aimed at customer service teams that want to collaborate from a single dashboard.

For organizations that need an omnichannel inbox and want to bundle multiple social channels, Trengo is a strong choice. But when the challenge is not so much managing channels, but automating business processes — think routing emails, phone accessibility, or optimizing intake — Callidus Works offers a fundamentally different solution.

The difference: inbox management vs. process automation

Trengo is built as a communication platform: it centralizes channels and helps teams collaborate on conversations. Callidus Works is built as process automation: incoming messages are not just answered, but also routed, enriched, and validated before entering the next process step.

At Trengo, the team inbox is central. At Callidus Works, the process is central — from intake to completion.

Where Callidus Works goes further

Callidus Works combines three AI agents in one platform: the Chat-Agent, the Mail-Agent, and the Call-Agent. Where Trengo includes email as a channel in the inbox, Callidus Works' Mail-Agent processes emails as part of the business process — including routing based on multiple knowledge bases and automatic validation.

Additionally, Callidus Works offers a Call-Agent for automating phone traffic, something Trengo does not provide. And the Inflow Handler optimizes the complete intake of business processes: orders, requests, and complaints are automatically routed to the right team.

Start fast, scale smart

Just like Trengo, you can get started with Callidus Works quickly — operational within one day — and easily expand later. An important difference is price: where Trengo starts at €299 per month, Callidus Works offers an operational AI agent from just €50 per month. Additionally:

• Multiple routing rules based on different knowledge bases
• API connections with existing systems
• Scalable plans that grow with your usage

For which organizations?

Callidus Works is particularly suited for organizations where:

• Email is the starting point of operational processes (orders, requests, complaints)
• Incoming messages need to be routed based on content and knowledge bases
• Phone traffic needs to be automated in addition to chat and email
• The goal is process automation, not inbox management
• An affordable and scalable solution is desired
