Pricing model

Pricing changes often and each tool prices differently (per seat, per minute, per call, or usage based). Rather than freeze a number that goes stale, we link straight to each vendor’s own pricing page so you see the current model at the source.

What customers say

Verbatim public reviews, praise and complaints both, each linked to where it was posted. We do not edit or cherry-pick for tone.

I used to think Sera was good because it was lightweight and easy to use. I liked that it didn't hang up and it was easy to find stuff.

ServiceAgent's AI receptionist has completely transformed our front desk. We went from missing 40% of calls to capturing every single one — even during summer rush.

Praise
During last summer's heat wave, we handled 3x our normal call volume without hiring a single extra person. The AI just kept answering.

Praise
The after-hours coverage alone has paid for itself. We're booking emergency calls at 2am that we used to lose to competitors.
