Running the diary, the deposits and the website for a salon, barber shop or treatment studio.
A missed colour appointment is three hours of a stylist's day that cannot be sold to anybody else. The fixes run in a specific order, and deposits are not first.
Most salon clients are loyal to a person, not a shop. A diary that cannot express that loses the booking or gives it to the wrong chair.
Hair length, thickness and what the last salon did all change the price. A single figure is either a promise you break or a number that scares people off.
A colour client needs a patch test 48 hours ahead. If your booking page does not know that, you find out on the day and lose both slots.
Deposits fix the bookings that were never going to happen. They also cost you the ones that were. The difference is which appointments you apply them to.
Every salon has a day that does not sell. The usual answer is a blanket discount, which trains your busiest clients to pay less for the slot they already wanted.
Barbers run on walk-ins, short slots and a queue. Most salon advice assumes the opposite, and following it quietly breaks the thing that was working.
Almost nobody searches for a salon by name. They search for a treatment and a place, and the salon that answers both in the right order gets the click.
