Treatwell is mainly focused on online bookings and therefore lacks a lot of the other features you need as a salon to manage your business, like client data storage, email marketing, retail product promotions, client checkout, sales reports, etc. Slick will provide a complete solution for salons.
Treatwell is not integrated with your salons calendar. As Treatwell only allows bookings into the Treatwell calendar, it can’t support bookings from the salon’s website or other sources so you run the risk of double bookings if running two systems simultaneously.
Treatwell charges you 20%-30% commission of every booking made via Treatwell. Slick will not charge a commission fee for salon customers.
