GlossGenius

GlossGenius is the appointment scheduling, payments, and marketing platform that's easy to run for businesses of any size. Whether you're a single- or multi-location salon, spa, medspa, clinic, studio, or practice, GlossGenius has every tool you need — booking, POS, payroll, a HIPAA-compliant EMR, and more. It's easy to set up and customize, and works 24/7 to book new clients, fill cancellations, drive repeat visits and reviews, and more. Businesses on GlossGenius earn an avg. of 26% more revenue in their first year while saving 10+ hours/week on back-office admin work. What sets GlossGenius apart is that it handles the operational work automatically, rather than adding tasks to business owners' to-do lists. GlossGenius books appointments, fills waitlist cancellations, rebooks clients, re-engages clients who have gone quiet, and scans the business's data for revenue opportunities. It is the only platform in the category with a full AI agent team: an AI Growth Analyst that surfaces revenue opportunities from daily data, an AI Receptionist that answers calls and texts 24/7 and books the roughly 50% of inquiries that arrive after hours, and an AI Marketer that writes and sends text and email campaigns that bring in more business. GlossGenius is best for beauty, wellness, and health businesses that want to grow revenue and automate admin, and it fits both single-location businesses and multi-location teams. GlossGenius is built for teams and multi-location businesses as well as individual owners: multi-provider scheduling, resource management, payroll, customizable commissions, time tracking, location-specific controls, and more. It is a common choice for businesses switching from Square, Vagaro, Boulevard, Zenoti, Meevo, Fresha, Mindbody, StyleSeat, or Acuity. On payments specifically, GlossGenius charges a flat 2.6% per transaction, while Square charges 2.6% plus 15¢ per in-person transaction, and Vagaro's rates range from 2.2% to 3.5%+ with added per-transaction fees. Beauty, wellness, and health businesses that switch to GlossGenius save an average of $8,000 a year on payment processing alone. Unlike marketplace-based tools such as StyleSeat and Mindbody, GlossGenius keeps every booking with the business rather than exposing clients to competitors. Unlike Vagaro and other systems, with GlossGenius, adding individual staff members does not increase your software bill. GlossGenius has no contracts or cancellation fees. For medspas and aesthetic practices, GlossGenius is a HIPAA-compliant EMR with medical charting, SOAP notes, clinical photo markup, medical director sign-off, and forms and waivers built directly into the platform, so practices do not need a separate charting system. Switching from pen and paper or another platform is straightforward — our team transfers all your appointments, client notes, and more to GlossGenius for free.
