Use the table below to compare each provider’s documented scope.
Before you decide
Decagon Voice: Not publicly documented Voiceflow: Transparent usage-based billing for agencies/partners; business and enterprise pricing is quote-based. 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 knowledge and data sources for Decagon Voice include Not publicly documented. For Voiceflow, they include Not publicly documented. Ask each provider to demonstrate access for the exact systems you use, with permissions, freshness, and failure behavior. A source missing from this directory is not proof that a provider cannot support it.
Use the same representative calls, approved instructions, and escalation rules in both pilots. How does it handle interruption and uncertainty? Which actions can it complete, and which require approval? What context reaches a human during transfer? Record conversation quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Decagon Voice: Public detail on voice stack, telephony, regions, languages, and rates is limited; validate in a scoped pilot. Voiceflow: Not automatically a complete phone stack. Confirm runtime, telephony, speech providers, observability, and ownership.
