AI Receptionist Pricing Explained: Per-Call vs Flat-Rate (2026)

The most confusing part of buying an AI receptionist isn't the AI — it's the pricing. Two vendors can both charge "about $100 a month" and cost you wildly different amounts depending on how they count. Here's how the models actually work, with real numbers.

The two pricing models

Flat-rate

One monthly price, unlimited (or generously capped) calls. Example: ElevenLabs Reception at a verified $29/mo. Your bill is predictable; high call volumes are effectively discounted.

Per-call / per-minute

You pay for what you use — per answered call or per minute of talk time. Cheap at low volumes; can surprise you in a busy month or storm season. Always ask how spam calls are counted.

VERDICT

Math is illustrative. Enter the actual rates from the vendors you're comparing — and remember to ask whether spam calls count toward per-call billing.

Rules of thumb

Hidden costs to ask about

  1. Setup/onboarding fees — some vendors charge to configure your call flows.
  2. Spam counting — do robocalls burn your minutes? Get it in writing.
  3. Overage rates — what happens when you exceed the plan's included calls?
  4. Integration fees — is the ServiceTitan/Housecall Pro connector included or an add-on?
  5. Contract length — month-to-month vs annual; what does cancellation actually require?

Frequently asked questions

Is per-call or flat-rate cheaper for a small contractor?
It depends entirely on call volume — use the calculator above with real vendor quotes. As a rule of thumb, flat-rate wins above roughly 100–200 calls/mo, and it's the safer choice if you get seasonal spikes (storm season, heat waves).
What's the cheapest AI receptionist available?
The cheapest verified flat rate we found (September 2026) is ElevenLabs Reception at $29/mo; Upfirst was observed from $24.95/mo. Voksha ($14/mo) and Dialzara ($29/mo) were seen advertised but not verified on vendor pricing pages.
How does AI receptionist pricing compare to a human answering service?
AI runs $29–$300/mo; human services like Ruby or Smith.ai run $245–$800/mo. The gap is roughly 5–10x — which is why the real question isn't whether AI is cheaper, but whether the call quality meets your bar. Test it.
Do free trials require a credit card?
Varies by vendor and changes often. Make 'no credit card required' a checklist item when you compare — it's the lowest-risk way to test on real calls.
