The table below preserves each vendor’s scope and qualifiers. An unlisted feature is unverified here; it is not a claim that the feature is unavailable.
Before you decide
Zendesk AI: Agent licenses plus AI resolution usage. Support Team and Suite Team include 5 automated resolutions per agent/month; Suite Professional includes 10, subject to a 10,000 annual cap. Messaging AI requires messaging access; advanced AI capabilities may require another package. Voiceflow: Usage-based billing for agency and partner workspaces; business pricing depends on deployment scope and self-serve or managed implementation. Ask for current plan, usage, collaborator and telephony charges before budgeting. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.
The recorded sources for Zendesk AI include Zendesk Knowledge; ticket history; help center; connected business systems. For Voiceflow, they include websites; documents; knowledge bases; APIs; structured data. Ask each vendor to demonstrate ingestion or live access for the exact system you use, with permissions and refresh behavior. A source missing from this directory is not proof that a vendor cannot support it.
Use the same sample of real support requests, approved knowledge, and escalation rules in both pilots. Can it cite or restrict answers to approved knowledge? What happens when the agent is uncertain? Which actions can it complete beyond answering? Record answer quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Zendesk AI: AI consumption is measured by automated resolutions/allowances; confirm current allowance and overage terms. Voiceflow: Credits and external telephony/model charges apply; confirm included editors and production limits.
