If deposits are a must, prioritize these

If your business must take deposits at booking, the strongest free/free-tier options are usually:

1. Square Appointments
2. Fresha
3. SimplyBook.me

If you also need multi-staff assignment, all three can handle it, but the smoothest experience depends on your business type and region.

Quick recommendations by business type

• Solo service provider: Square Appointments
• Salon/spa/wellness: Fresha
• Custom scheduling with forms and rules: SimplyBook.me or Acuity
• Small team needing basic booking: Setmore
• Need the most polished payments/deposits: Square Appointments

Important note about “free”

Many booking tools are “free” only in the sense that:

• basic booking is free,
• but deposits/payment processing fees still apply, and
• team features, SMS reminders, custom branding, or advanced automation may require paid plans.

If you want, I can also give you:

1. a comparison table,
2. the best free tool for your specific business type, or
3. a list of open-source/self-hosted booking tools.
