Real-World Use Cases
Scenario 1: Freelance Consultant
Best choice: Cal.com (Free)
You need basic scheduling without paying monthly fees. Cal.com's free tier gives you unlimited event types, custom branding, and all the essentials. Upgrade to Pro ($12/mo) only when you need routing forms or workflow automation.
Scenario 2: B2B Sales Team
Best choice: Calendly (Teams plan)
Your team needs round-robin scheduling, Salesforce sync, and analytics. Calendly's deep CRM integrations and enterprise features justify the $16/user/mo cost. The polish and reliability matter when prospects are booking.
Scenario 3: Life Coach / Therapist
Best choice: Acuity ($27-49/mo)
You sell packages (e.g., "10 sessions for $800"), need detailed intake forms, and want clients to self-reschedule. Acuity's service-business features are worth the premium over generic scheduling tools.
Scenario 4: Open-Source / Privacy-First Startup
Best choice: Cal.com (Self-hosted or Pro)
You want to self-host on your infrastructure, use webhooks for custom integrations, and avoid sending customer data to third parties. Cal.com is the only option with full control and transparency.
Pricing at Scale
Here's what you'll pay for a team of 5 users:
| Plan Level | Cal.com | Calendly | Acuity |
|---|---|---|---|
| Basic features | $0 (Free tier) | $0 (Free tier) | $16/mo (1 user) |
| Professional | $60/mo (Pro × 5) | $75/mo (Professional × 5) | $27/mo (1 user) |
| Teams | $75/mo (Teams × 5) | $80/mo (Teams × 5) | $49/mo (multi-staff) |
Note: Acuity pricing is per account (not per user), so multi-staff plans are more cost-effective for service businesses.
Migration: Switching Tools
Worried about lock-in? Good news: all three tools support calendar exports and link redirection.
Switching from Calendly to Cal.com
- Export your event types (manual copy/paste)
- Connect your calendars to Cal.com
- Set up redirects from old Calendly links (or update email signatures)
- Total time: ~30 minutes
Switching from Acuity to Calendly/Cal.com
- Export client list (CSV)
- Recreate event types in new tool
- Update website embed codes
- Notify clients of new booking link (optional)
The switching cost is low — don't let fear of migration lock you into a suboptimal tool.
What About Other Tools?
There are dozens of scheduling tools. Here's why I didn't include them:
- Microsoft Bookings: Free with Microsoft 365, but clunky interface and limited features. Only worth it if you're already all-in on Microsoft.
- Google Calendar Appointment Slots: Basic and free, but no custom branding, automation, or team features. Fine for ultra-simple use cases.
- SimplyBook.me: Similar to Acuity but with outdated UI. Acuity is better for most service businesses.
- Doodle: Great for finding meeting times among groups, but not a booking tool per se.
- Chili Piper: Enterprise inbound conversion tool ($15K+/year). Overkill for small businesses.
Common Questions
Can I use these tools with multiple calendar accounts?
Yes! All three sync with Google Calendar, Outlook, iCloud, and other CalDAV calendars. They check availability across all your connected calendars to prevent double-bookings.
Do these tools work internationally?
Absolutely. All three support multiple time zones, automatically detect booker locations, and display availability in their local time. Cal.com even lets you self-host in your region for data sovereignty.
Can I embed these on my website?
Yes. All three offer embed codes (iframe or popup) that you can add to your website. Cal.com's embedding is especially flexible with customization options.
What happens if someone books during a buffer time?
All three tools support buffer times (e.g., 15 min before/after meetings). They automatically block those slots so you're not triple-booked.
Can I require payment before booking?
Cal.com Pro and above, Calendly Professional and above, and all Acuity plans support Stripe/PayPal payment collection. Perfect for consultations, coaching sessions, or paid workshops.
Final Recommendation

Unless you have specific enterprise needs, Cal.com offers the best combination of features, price, and flexibility. The free tier is genuinely unlimited, and even the Pro plan ($12/mo) undercuts competitors while adding workflow automation.
🥈 Best for Enterprise Sales: Calendly
If you're in B2B sales with CRM integration needs, Calendly's polish and ecosystem are worth the premium. The brand recognition alone can boost booking rates.
🥉 Best for Service Businesses: Acuity
