The short answer
Microsoft 365 Copilot Business ranks higher on Top 11 (#4 vs #5) for Owners of United States small businesses, roughly 1 to 50 people, who miss calls while they work and want an AI receptionist that books the appointment and logs the caller, not one that only takes a message. / Owners, founders and operations leads at United States companies under 500 people who have decided to buy an AI agent, have no engineer on staff, and want to know which one to pay for, what it costs at five or fifty people, and which of them is wrong for their business.. Cheapest agent to deploy if you already run Microsoft, because deployment is a licence change.
