The interface is very user friendly, it's not too technical to use but easy enough for even non-technical users or employees who are still learning how things work online! I can't think of anything negative about this software so far; however there have been times when you could only save certain documents as an attachment instead if uploading them directly into files through their system (this was solved by contacting support). We're using competencty book mainly because we don’t want our clients being able access any information regarding us without permission from ourselves first which helps keep some aspects confidential between parties involved within each service contract/project agreement etc..
