Strong and comprehensive software, could be too much for your use case
Onepoint is a very comprehensive software with all functionalities I was looking for. I am especially impressed by the What-If scenario planning that helps me managing uncertain parts of projects. Also the resource utilization view is an advanced functionality that makes Onepoint stand out. Service and tech is also on point.
Smaller companies should keep in mind if the software is "too much" for their use case. Given its wide functionality, it is easy to use, but still something to consider. I don't see other Cons.
