The models' case: Deep appointment logic for service businesses — per-service durations, buffers, padding, intake forms, packages/memberships, multiple staff calendars, and client. The models' main caveat: Squarespace-owned and priced/positioned around their ecosystem. The strongest alternative is Square Appointments — Best overall for a payment-taking local service business in a Square-supported market: capable online booking, unlimited staff calendars, reminders. Not unanimous: ChatGPT picks Square Appointments; Gemini picks Calendly; Grok picks Setmore.
