AI receptionist pricing runs roughly $50 to $800 per month for small businesses, but the pricing model matters more than the sticker. Metered services bill by the minute, the call, or the unique caller, so the bill rises on busy months. Flat-rate services like RingRouteUSA charge one price ($149 to $799/mo) no matter the volume.
Almost every AI receptionist falls into one of two camps. Metered plans charge for usage: per minute of talk time, per call answered, or per unique person who calls you. Your bill moves every month with volume, and a seasonal rush or a marketing push pushes it up. Flat-rate plans charge one price regardless of how many calls come in. The bill is the same on your slowest and your busiest month.
Neither is universally cheaper. On a light-volume month, a low metered tier can win. Flat-rate pulls ahead on predictability and once you are busy, because metered costs climb while flat-rate does not.

| Phonely Unlimited concurrency; BAA gated to Enterprise | Per minute | $50/mo (free tier too) | Yes, ~$0.25-0.30/min overage |
| Ruby Real human agents; $720 buys ~200 min | Per receptionist-minute (human) | $250/mo (50 min) | Yes, overage per minute |
| Smith.ai Pricing hidden; reported AI entry ~$95 | Per call (human + AI) | Not public / requires demo | Yes, overages + add-ons |
Ruby, Goodcall, and Phonely prices are from their own 2026 pricing pages. Smith.ai has removed public pricing; its figures are reported third-party and should be confirmed with a quote. Prices change often, so re-verify before relying on any number.
The story is in the busy month. Take a business getting about 800 unique callers. On Goodcall's mid tier, that is roughly $129 base plus 550 callers over the cap at $0.50, about $404 for the month. RingRouteUSA Professional is a flat $349 no matter how many people call. This is an illustrative estimate, not a vendor quote, but it shows the pattern: as volume climbs, metered passes flat-rate.
If your call volume is low and steady, a metered entry plan may cost less, and that is a fair choice. If your volume is spiky, seasonal, or growing, or you simply want a bill you can predict and a price you can see without a sales call, flat-rate is the safer pick. Use the missed-call calculator to weigh the cost of a missed call against a flat monthly fee.
A low entry price is real savings only if your volume stays low. The moment calls climb, metered plans add overage and the effective price rises. Read the pricing model, not just the headline number.
Metered and enterprise-style vendors often gate pricing behind a demo so the quote can be tailored to your volume. Smith.ai, for example, now shows a lead form instead of tiers. Published pricing is itself a buyer benefit.
Flat rate: Starter $149/mo, Professional $349/mo, Enterprise $799/mo, all with unlimited concurrent calls. Re-confirm current pricing on the pricing page.
