Intercom vs Zendesk vs Biz AI Last

Choosing a customer service platform used to be simple: you chose Zendesk for tickets or Intercom for chat. In 2025, the landscape has changed. AI is now at the center, and pricing models have become increasingly complex. Here's how the three leaders stack up.

1. Intercom: The "AI-First" Platform

Intercom has pivoted heavily into AI with their Fin AI agent. It's powerful, but it comes with a "success tax" — you pay $0.99 for every question it resolves. For high-volume businesses, this can double or triple your monthly bill unexpectedly.

• Best for: Large teams that need sophisticated outbound messaging and product tours.
• The Catch: Scaling costs and per-seat fees.

2. Zendesk: The "Legacy King"

Zendesk remains the most comprehensive ticketing system. However, it can feel bloated and overly complex for smaller teams. Their AI features (Zendesk Advanced AI) often require higher-tier plans and significant configuration.

• Best for: Enterprise companies with thousands of tickets and complex workflows.
• The Catch: Steep learning curve and "hidden" complexity.

3. Biz AI Last: The "Simplicity Winner"

Biz AI Last was built for one thing: getting your support live and automated in minutes. Unlike the others, it includes Live Audio and Video Chat natively, and it charges one flat $100/month price for unlimited agents and unlimited AI resolutions.

• Best for: Growing businesses that want predictable costs and the latest engagement channels.
• The Catch: Fewer enterprise-specific "product tour" features than Intercom.
