Looking for a great way to book unexpected empty appointment times at your spa? Take a hint from International Orange (IO) in San Francisco, which just launched IO Stand-by, an offering of discounted last-minute day-of facial and massage appointments made available to clients by phone only. The IO Stand-by program provides clients with exclusive access to same-day deals on IO massage and facial treatments. Bookings are on a first-come, first serve basis as appointments become available. To get on the IO Stand-by list, clients must sign up and complete an online form to select their preferred dates, times, and treatment of choice. Based on their preferences, clients will be contacted by phone only and on their preferred days when there is a match based on availability. Sounds like International Orange is helping clients make the most of their time while helping their own bottom line.
