Best Free Scheduling Software for Small Business in 2025

Small businesses need scheduling software that is free, reliable, and easy for clients to use. This guide compares the best free scheduling tools available in 2025, with honest looks at their limitations.

1. Cal.com (Free Tier)

Unlimited event types, one calendar, basic integrations, and optional self-hosting. The free tier is more generous than Calendly’s. The catch: some advanced features require technical setup if self-hosting.

2. Calendly (Free Tier)

One event type, one calendar, clean interface, strong brand recognition. Clients trust Calendly links. The limitation is the single event type, which forces workarounds for businesses offering multiple services.

3. Microsoft Bookings

Free with Microsoft 365 Business Basic ($6/user/mo). If you already use Outlook and Teams, this integrates seamlessly. Not truly free standalone, but close if you are in the Microsoft ecosystem.

4. When2meet

Completely free, no signup required, great for finding a time that works for a group. Not suitable for client booking, but perfect for internal team scheduling.

5. SavvyCal

No free plan, but a 7-day full trial. Included here because solopreneurs often find the one-time switch worth it. Custom branding and elegant UX out of the box.
