Before using Booking Manager System, we were creating our offers at the beginning of the year and then copy and paste them manually when someone made an inquiry.
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 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.
