Online appointment booking refers to the process in which customers book appointments independently over the internet, without contact by phone or in person, around the clock, 365 days a year. It is a form of digital self-service that has become standard in more and more industries since the early 2000s. What used to be organized exclusively by phone, email or in person now runs largely automatically. Online appointment booking has fundamentally changed the way services are booked.
Historical development
The first online appointment booking systems emerged in the early 2000s, initially mainly for doctor's offices and hair salons. With the spread of smartphones and mobile internet from 2010 onward, demand grew exponentially. Today, customers in almost every industry expect to be able to book appointments online, from the auto repair shop to the tax advisor to the city administration.
