Use the table below to compare each provider’s documented scope.
Before you decide
Parloa AMP: Consumption-based enterprise pricing tied to task complexity and effort, with proposals scoped to interaction volume and use case. Retell AI: Pay-as-you-go per-minute component pricing with optional add-ons; Enterprise uses custom volume pricing and terms. 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 Parloa AMP include Not publicly documented. For Retell AI, 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: Parloa AMP: Request the task-complexity definition plus services, languages, concurrency, carrier, and model costs. Retell AI: Component rates may not equal complete cost. Confirm concurrency, premium model/voice, transfer, storage, QA, and carrier charges.
