Enterprise AI Agents for Customer Service (2026)
Enterprise CX agent vendors don't publish dollar rates, so the useful comparison is the billing unit: per minute, per conversation, per resolution or per outcome. Details below come from each vendor's own pricing or product pages.
PolyAI, Parloa, Sierra, Decagon and Cognigy compared on how they bill and what they're built for.
| Tool | Billing | Best for |
|---|---|---|
| Per minute (quote only) | Enterprises automating high-volume customer service phone lines | |
| Consumption-based (quote only) | Enterprise customer service teams running AI agents across many use cases | |
| Outcome-based (quote only); blended/consumption available for some use cases | Large brands wanting CX agents across chat, voice and messaging with outcome-based pricing | |
| Per-conversation or per-resolution (enterprise quote) | Enterprise CX teams that want to own and iterate AI support agents across chat, voice and email | |
| Enterprise license; billed by conversations (and Voice Gateway concurrent lines) | Enterprise contact centers deploying voice and chat AI agents (NiCE Cognigy) |
