Estimated Floor (5 Seats · Enterprise / Custom)Custom Quote (Free plan · From $0/mo)Vendor does not publish a self-serve USD floor on its pricing page; requires sales qualification.Sales-gated pricing vs. $800/mo cap (High quote risk)

Tier Fit for 5-Seat Scale: Free ($20/mo): Unlimited booking, synced to your calendar
Primary Operational Bottleneck: Schema Extensibility: The platform enforces rigid component frameworks, preventing custom database schema definitions or external headless front-end deployments.

Estimated Floor (5 Seats · Growth / Professional)$55 / mo ($660 / yr on Growth / Professional)Stepped to Growth / Professional ($55/mo) for 5-seat team capacity (entry tier starts at $19/mo).Fits within $800/mo cap (7% of ceiling at base floor)

Published Self-Serve Entry Floor: Zendesk AI publishes a transparent entry point (From $19/mo) for initial validation before committing.
Tier Fit for 5-Seat Scale: Growth / Professional ($55/mo): Verified $55/mo published rate on vendor pricing schedule.
Primary Operational Bottleneck: Multi-turn Escalation Edge Cases: Highly nuanced customer inquiries that transition across disparate billing or account recovery states occasionally encounter premature fallback to human tier-1 queues.

Walk-Away Rule: Walk away if your documentation and macro repositories are fragmented or infrequently updated, leading to knowledge base synchronization drift and degraded agent accuracy.

Negotiation Lever: Leverage multi-seat Suite Professional tier commitments to negotiate the inclusion of the $50 per agent per month Copilot add-on at zero additional cost.
