We are using Booking Manager now for five years and it has made our work much easier. The program is good in general for running the business and having it all at one place, reachable from wherever you might be at the moment.
Booking Manager made our lives easier by helping us work faster and send our offers easier, create invoices with one click and send professional newsletters.
Booking Manager is one of our favorite partners, as the API data structure and performance is very good. We especially value the personal contact to the developers and their open-mindedness for constant improvement.
