At the beginning I thought I wouldn´t need to pay for a tool like ConceptShare because there are some other tools on the market which are free. A friend then showed me its functionality and I decided to get a plan. As a graphic designer who works with freelancers it is very important to convey in an easy way how graphical material needs to be changed or what has to be done. This is ConceptShare´s stronges point. I only use it for visual material and its functions are brilliant and very useful.
