The four ways this market charges you — all verified 2026-11-09

Every AI voice receptionist on the market is the same stack underneath — a phone line, speech-to-text, a language model, a voice, and a prompt. What you are actually comparing is the billing model wrapped around that stack. All four pricing models below were checked against the vendors' own pages on 2026-11-09.

VendorBilling modelPublished price (checked 2026-11-09)What the headline doesn't say
Vapi Usage — per minute $0.05/min platform fee + AI model and telephony pass-through (Deepgram ~$0.0095–$0.0099/min, OpenAI $0.0077–$0.0452/min, ElevenLabs $0.0146–$0.0238/min); ~$0.08–$0.13/min all-in estimated. Success support: Core $29/mo, Pro 10% of hosting ($999/mo min), Premier custom. HIPAA add-on $2,000/mo. +$10/line/mo concurrency, +$20/org/mo. (All rates checked 2026-11-09.) It ships an API, not a receptionist. The build, prompt, test, and maintenance hours are yours — price them in or you are comparing a parts kit against an appliance.
Dialzara Flat plan — minute caps Business Lite $29/mo (60 min, $0.48/min over), Pro $99/mo (220 min), Plus $199/mo (500 min), Elite $349/mo (1,000 min). Done-For-You from $1,500/mo. Outbound voice $750–$1,500/mo. SMS agent $19/mo + $0.05/msg; chatbot $39/mo free with voice. (All rates checked 2026-11-09.) The steepest overage rate ($0.48/min) sits on the lowest-priced plan. No contract — but terms state no refunds, so a mid-cycle cancel forfeits the paid remainder.
Goodcall Flat plan — unique-customer caps Starter $79/mo (100 unique customers, then $0.79 each), Growth $129/mo (500, $0.26 each), Scale $299/mo (2,000, $0.15 each). Free demo agent before you pay. (All rates checked 2026-11-09.) It meters customers, not minutes — the growth tax lands on a different axis. Call-history retention is tier-bound (30 days Starter, unlimited only at Scale), so your own records expire behind the paywall.
Podium Quote-gated contract Publishes no number — the pricing page routes every buyer to sales (checked 2026-11-09). Last published anchor ~$399/mo (checked 2026-09-27). AI Employee add-on "Jerry" attaches to any plan. The opacity is the product. Every quote opens a negotiation, and negotiations favor the side with the price list — which is never you.

The fifth option the comparison sites skip: ownership

The four rows above are the same components resold four ways. The components themselves — speech-to-text, a language model, text-to-speech, telephony — are available at pass-through cost inside your own Twilio and cloud accounts. A voice agent built that way has no platform margin, no call cap, no per-customer meter, and no exit negotiation: the agent, the prompts, and the call history stay in accounts you control. That is the build DGF delivers — scoped once at a published one-time price, owned outright. The honest tradeoff is real too: ownership needs someone to build and maintain it, which is what the engagement is for.

How to pick a band

  1. Under ~10 missed calls a week: you do not need any of these — a missed-call text-back on a $15–25/mo phone tool (checked 2026-10-14) covers the leak for a tenth of the price. See the missed-calls fix.
  2. 10–30+ missed calls a week, routine questions: the productized band (Dialzara $29–$99/mo entry tiers, checked 2026-11-09). Watch the overage rate, not the tier headline.
  3. You are technical or already paying a developer: Vapi-class usage pricing is the lowest real unit cost — after you price the build hours honestly.
  4. You want the system, not the subscription: the sovereign build — one-time scoped price, components at pass-through cost, no monthly platform fee on top.

Three questions to ask before signing anything

  • What is the overage rate? The tier headline is not the price — the per-minute or per-customer rate above the cap is. Dialzara's is $0.35–$0.48/min by tier (checked 2026-11-09).
  • What happens to my number and my call history if I leave? Numbers usually port; transcripts usually don't. Goodcall expires history behind the paywall; Podium's SMS flows do not export (wall-checks linked above).
  • What is the HIPAA answer in writing? For medical offices: Vapi's HIPAA add-on is $2,000/mo (checked 2026-11-09). Whether any setup meets statutory requirements depends on configuration and legal counsel — this is pricing analysis, not legal advice.
