The interface of krok has an amazing layout that makes it easy not only in using but also understanding what's going around with my projects as well! I have been working at Kroks since its very early stages so i'm able to give feedback about how their service could improve upon or be improved more than most other competitors out there because we were actually involved from day one!! Nothing really comes into mind aside form being extremely user friendly which helps me understand things easily without having much knowledge when starting up new accounts/projects etc.. Also they are open minded towards any suggestion made by customers who want help solving problems related specifically within our services provided (and this includes clients too!). They do listen. And take advantage off them whenever possible instead just ignoring suggestions like others would probably think if asked "what can u possibly offer??" Well here goes :). We solved issues regarding time tracking & billing system integration among freelancers through.
