- ✗ Hard minimum of 50 seats -- excludes all SMBs (50 seats = $7,450+/mo minimum)
- ✗ Per-agent pricing makes scaling extremely costly
- ✗ Complex implementation requiring professional services (2-8 weeks)

Our Verdict
Five9 is a proven enterprise contact center platform ideal for organizations that need a full-featured CCaaS solution with human agents, workforce optimization, and omnichannel support. However, its per-agent pricing starting at $175/mo makes it expensive, especially for businesses that want AI-only automation. Kallina is a cost-effective, AI-native alternative for businesses that want autonomous voice agents without the overhead of a full contact center platform. If you have human agents and need enterprise CCaaS, Five9 is a strong choice. If you want AI agents handling calls autonomously, Kallina is significantly more affordable and faster to deploy.
