The three pricing models, and how to compare them
UK call answering is sold three ways: per call, per minute, or as a monthly bundle of calls or minutes. Per-call pricing is simple but climbs with your call volume. Per-minute pricing rewards short calls and punishes chatty ones. Bundles smooth the bill but you pay for allowance you may not use, and overage rates apply beyond it.
The only fair way to compare them is the effective per-call rate: divide the monthly bill you expect by the calls you expect answered. A £75 bundle covering 30 calls is £2.50 a call. A quote that looks cheaper per month can be dearer per call, which is the number your missed-call maths actually runs on.
