Pricing
PaidZendesk AI is bundled into Zendesk's Support and Suite plans rather than sold on its own. Support Team starts around $19 per agent/month (annual billing) for email-only ticketing. Suite Team starts around $55 per agent/month and adds messaging, live chat, and voice. Suite Growth runs roughly $79 per agent/month, adding SLAs and CSAT surveys. Suite Professional runs $115 per agent/month, adding advanced routing, real-time analytics, and up to five help centers. Suite Enterprise is custom-quoted (previously listed around $169 per agent/month) and adds custom roles, sandbox environments, and multi-brand support. AI agents are included in every Support and Suite plan with a monthly automated-resolution allowance (roughly 5 resolutions per agent on Team plans, up to about 15 on Enterprise); overage is billed per resolution, at approximately $1.50 with committed volume or $2.00 pay-as-you-go. Copilot is a separate add-on at roughly $50 per agent/month, Quality Assurance is roughly $35 per agent/month, and Workforce Management is roughly $25 to $50 per agent/month. Monthly (non-annual) billing runs 15-30% higher than the annual rates above. A 14-day free trial is available; there is no permanent free plan.
FreemiumVoiceflow offers a Free (Starter/Sandbox) plan for prototyping and evaluation with a one-time credit grant (roughly 100 credits/month) and access to limited LLM models, ideal for testing before committing to a paid plan. The Pro plan starts around $60/editor/month (about $50/month effective on annual billing) and adds access to all major LLM models with higher usage limits for individual builders or small teams. The Business (Team) plan starts around $150/editor/month and includes roughly 30,000 credits, 5 workspaces, up to 10,000 knowledge sources, LLM fallback models, unlimited agents, priority support, and around 15 concurrent voice calls, aimed at growing teams. Enterprise pricing is custom (commonly cited in the $1,000-$2,000+/month range or higher depending on volume) and includes unlimited credits and agents, SSO, private cloud hosting, dedicated account management, migration support, and custom SLAs. Additional editor seats, phone numbers, and credit overages (for LLM usage, voice minutes, and messages) are billed on top of the base plan. Annual billing offers roughly a 10% discount. A separate Agency & Partner track offers a free trial with no credit card required and usage-based billing for teams building agents for clients.

- Resolution Learning Loop continuously improves automation quality from real outcomes
- Broad multi-LLM support gives flexibility and resilience across model providers
- AI agents support 80 languages with native fluency for global support teams

Cons
- Pricing is complex, layering per-agent seat costs with a separate per-resolution AI meter that is not published transparently

- Copilot and Quality Assurance are separate paid add-ons rather than bundled into base plans

Cons
- Pricing is largely demo-gated and not fully transparent, especially for Business and Enterprise tiers
