Cost Analysis (12-Month Comparison)

Our Recommendations

Choose FullyBooked If:

• You run a service-based business (beauty, healthcare, fitness)
• No-shows are costing you significant revenue
• You want SMS reminders without extra costs
• You need a generous free plan to test with
• You're based in Australia or the US

Choose Acuity If:

• You need extensive customization options
• You already use Squarespace
• You offer complex packages and require detailed intake forms
• Budget isn't a primary concern
• You have time to learn a complex system

Choose Calendly If:

• You primarily schedule meetings, not services
• Simplicity is your top priority
• You need extensive third-party integrations
• Your team is distributed globally
• No-shows aren't a major problem for your business

The Bottom Line

For service-based businesses, FullyBooked offers the best combination of features, pricing, and no-show prevention. The free plan alone provides more value than Calendly's paid plans for appointment-based businesses.

Acuity is the most feature-rich but comes at a premium price and complexity cost. It's overkill for most small businesses.

Calendly excels at simple meeting scheduling but lacks the service-specific features that appointment-based businesses need.

Ready to Make Your Choice?

Start with FullyBooked's free plan to test it with your real business needs. You can always upgrade as you grow, and the no-show reduction alone typically pays for the software within the first month.
