1. Acuity Scheduling
Best for flexible paid appointments
What it does better than Square Appointments
Acuity is payment-agnostic (it works with Stripe, Square, or PayPal) and offers deeper intake forms, packages, memberships, and class scheduling than Square Appointments. That flexibility suits coaches, clinics, and studios that do not fit a retail POS model.
Where Square Appointments still wins
It has no free plan and no integrated in-person POS or payment hardware, which Square Appointments provides natively.
Best for: Service businesses that want appointment depth and freedom to choose a payment processor.
