Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Capacity

  • Two-part pricing, an annual platform fee plus usage, so the bill is not knowable from the tier alone
  • AI usage is metered by channel: per response on chat and email, per minute on voice and per message on SMS
  • Agent Assist and conversation intelligence are charged per hour of agent time on top
  • Live chat, agent assist and conversation intelligence require the Pro tier
  • The HIPAA package and advanced workflows are Enterprise only
  • No prices are published for any tier

Kayako

  • The AI agent is billed at $1 per resolved ticket, so support cost scales with ticket volume rather than being a fixed subscription
  • A resolution counts when the AI solves the issue without human involvement, so the definition of a billable event is set by the vendor's own system
  • No per agent monthly price is published for the full Kayako One platform
  • Full platform pricing requires talking to an expert
