It is very easy to use, it has all features that we need in an enterprise resource management system. The support team is always ready to help us out whenever required. I would say nothing much as far its functionality is concerned but if there are any issues regarding customization then they might be able to customize according to our needs. We have used this product since last 10 years now, so no complaints about the past version also. As compared to other softwares we were using before, this one was easier to install and configure.
