What to look for

Decide what you're booking

People, classes, or resources? Make sure the tool models your actual unit of booking, including capacity and waitlists for classes.

Payments should be native

Taking payment or a deposit at booking is the difference between a reservation and a hope. Prefer built-in Stripe over add-ons.

Reminders reduce no-shows

Automated reminders are the highest-ROI feature in booking software; insist on SMS and email.
