SageOne accounting on Safari

macOS and Mac Apps

Hi all
Are anyone using the Sage One accounting software online via / .com?
The company I work for switched over to Sage One accounting software and I am required to use it, but so far I have very little luck. First thing I tried to do was create a quote, but I can't seam to choose a item using Voiceover, can't understand why, because I can choose a company just fine and they work with the same type dropdown menue.

I also have no luck on the Windows side on Internet explorer or Firefox.

Possible that I'm just a bit stupid on Safari because I'm quite new to the Mac, any help would be appriciated, I'm quite despret.
