Acuity Scheduling is an online appointment scheduling software company founded in 2006 by Gavin Zuchlinski. It was developed to help manage bookings for a massage therapy business. The platform offers a flexible and automated scheduling solution that streamlines appointment bookings, rescheduling, cancellations, and payment processing, allowing clients to manage their appointments independently.

The core service is customizable scheduling software that businesses can use to create dedicated scheduling sites or embed into existing websites. It features automated workflows, calendar management, and integration with payment processors like Stripe, Square, and PayPal. Acuity Scheduling is particularly beneficial for businesses with appointment-based operations, such as health and wellness providers, consultants, and educators. The company handles over 15 million appointments monthly and offers tiered subscription plans starting at $16 per month, making it accessible for various business sizes. Acuity Scheduling was acquired by Squarespace in 2019, enhancing its capabilities while continuing to operate as a standalone product.
