Smith.ai is the gold standard of human answering services: real agents, solid intake, a serious brand. Their model carries a structural cost — humans paid by the hour — which shows on the invoice: $300 for 30 calls, then $8.50–11.50 per overage call. For a firm receiving sensitive matters and wanting a human voice on every call, it's a rational choice.
FAQ

Smith.ai or Harch Signal for a tradesperson?
For a tradesperson with a $300–800 average ticket, the question is economic: at $149 fixed, Signal pays for itself on one job. Smith.ai becomes rational above 100 qualified calls/month or for high-relational-value matters.
Is Smith.ai's AI comparable?
