How to choose
The right online booking software depends on whether you're booking professional time (calls, meetings) or managing service appointments with payments and staff.
Type of bookings
Virtual calls and meetings → Calendly or skdul. Service appointments with payments → Acuity or Square Appointments. In-person beauty/wellness → Fresha. Complex multi-provider services → SimplyBook.me.
Payment at booking
If clients need to pay a deposit or full fee when booking, you need a tool with built-in payment processing. Acuity, Fresha, Square Appointments, and SimplyBook.me all handle this natively.
Marketplace vs. direct booking
Fresha and Booksy include a marketplace that sends you new clients. Most other tools are direct-only — guests must have your link to book. If you're building a new client base, marketplace tools have a lead generation advantage.
AI features
For AI agent booking integration, only skdul has an MCP server. If your clients use AI assistants, skdul is the only platform where their AI can book with you autonomously.
