Before you decide
Salesforce Agentforce: Conversation or action-credit billing. A standard action consumes 20 Flex Credits, or $0.10 at the published pack rate; a conversation can contain multiple actions. Required Service platform licenses use annual contracts. Confirm the license bundle, action mix and additional services before estimating total cost. Retell AI: Voice cost combines infrastructure, speech, model, telephony and optional per-minute features. Chat is charged per AI message. Phone numbers cost $2/month; 20 concurrent calls are included, with additional concurrency $8/month each. Use the selected configuration to estimate the monthly bill. 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 Salesforce Agentforce include Salesforce CRM; Data Cloud; knowledge articles; external systems via APIs. For Retell AI, they include prompts; documents/knowledge bases; API tools; business systems. 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: Salesforce Agentforce: Total cost depends on Salesforce edition, credits, conversations and implementation; compare like-for-like units. Retell AI: Telephony, model, speech and other provider costs may be separate; technical integration work is expected.
