Is LobbyStack worth the price?

Good value

LobbyStack's pricing is fair for small businesses needing a basic AI receptionist, with the Free tier offering a useful trial and Starter at $30/month providing solid value for low-volume call handling.

The Pro tier at $100/month with 500 minutes is competitive, but overage rates of $0.18-$0.20/min can add up quickly for heavy users. Best for solo practitioners or small teams that want a simple, all-in-one solution without per-seat fees.

Hidden Costs & Gotchas

$0.20/min overage on Starter beyond 150 minutes

$0.18/min overage on Pro beyond 500 minutes

Which calendar services can LobbyStack sync bookings with?
