Global Project Tracker is a very useful tool for tracking project data and documents. It is very user friendly and has a very good search function. Occasionally it slows down a little bit. I would say that the support is very responsive and helpful. They are always willing to help you with any issues. I have been using Global Project Tracker for several years now and have never had any issues. I have used it for many different projects and am very satisfied with the product. I have used it for tracking project documents and data. It has been very helpful for tracking things like invoices and other project documents.
