This was my first job with Kolabtree. Ramya, the client, was amazing. She worked with me and set reasonable goals,expectations, and deadlines. She allowed for reworks as needed and provided excellent feedback and support. I would work with her and on Kolabtree again in a second.

I find the platform very helpful

Reviewed on 2021-04-27T06:43:11

I find the platform very helpful. However some of the features are a bit cumbersome, for example deadlines,to write a deadline when the client has not decided yet even when is he/she going to hire is somehow strange. Fees are a bit high, 20% is a lot of money, it would be good to try to lower it. I think once the fees have been transfer the projects should be closed by the application instead of having the client closing the project, they forget most of the time once the project is done and closed projects appear in your work area.
