Billing units differ, so compare the full allowance and overage terms.
The per-call maths most price pages avoid
Headline prices hide incompatible billing units. Ruby's published $250 plan includes 50 receptionist minutes, or $5.00 per included minute. AnswerConnect's $350 offer includes 200 minutes, or $1.75 per included minute before additional usage. Smith.ai's free AI plan includes 25 calls and lists a $3 per-call overage. These calculations compare allowance math, not service quality or equivalent outcomes.
Flat-price AI receptionists invert that: the more calls you get, the less each one costs. Clara starts at £39.99/month with no per-minute or per-call fees, and answers 24/7 including weekends and holidays at the same price. See Clara's pricing or the side-by-side provider comparisons.
And the option that looks free is the dearest: research by Invoca reports that missed calls are common and that many callers do not leave voicemail. Use your own call volume, booking rate, and job value to estimate whether a service is worthwhile.
