Comparing Smith.ai from the UK?

They're transparent about pricing, which is rare in this market. The question is whether per-call maths suits a UK small business.

The difference

How the two are priced.

Smith.ai charges per call. That means a short wrong number costs the same as a booked job.

Priced per call, not per minute

Thirty calls a month is $300 — around $10 a call.

Overage bites quickly

$8.50 to $11.50 for each call past your plan.

Dollars, and US-focused

Their pricing page makes no mention of UK availability.

FAQ

Questions, answered.

How much is Smith.ai?

Their published plans are $300/month for 30 calls, $810 for 90 and $2,100 for 300, with overage from $8.50 to $11.50 per call and a 30-day money-back guarantee (checked 9 August 2026). Their pricing page doesn't mention UK availability or GBP pricing.

Why does per-call versus per-minute matter?

Because a 20-second wrong number and a five-minute booking cost the same under per-call pricing. Most small businesses take a lot of short calls, which is why per-minute — or a flat plan with minutes included — usually works out cheaper.

Is RedAgents cheaper?

For a UK business, on published figures, yes — £29 a month for 100 minutes against $300 for 30 calls. But we're AI rather than a human team, so it isn't a like-for-like swap and we won't pretend it is.
