Ava handles inbound calls and SMS, books calendar slots, sends follow-up campaigns, and charges cards — all without requiring the owner to be present or approve routine transactions. The vendor describes natural-language commands as the primary control surface, meaning you instruct it in plain text rather than configuring settings menus. For a solo esthetician or personal trainer, this replaces the function of a part-time receptionist across after-hours windows. The ceiling appears when workflows grow past appointment booking into anything that requires nuanced exception handling — a refund dispute, a complex package negotiation, a client who needs a conversation before they will commit. At that boundary, Ava routes back to the owner, which is the right call, but it also defines exactly how far the automation reaches.
