The fact that it's completely open source software, with not only good support but excellent development team behind this product is awesome! I especially like how easy they make your life as an administrator of such program - all you need are few clicks - everything else takes care by itself ;) And the best part about them being Open Source Software? Their updates come pretty fast. We have been using FTRS since 2008 without major problems which speaks volumes already :) For our use case we were able to get some amazing benefits from this solution:- Fully integrated ERP- Transportation Management System.- Easy integration between different carriers/carriers' warehouses.- Centralized database makes reporting much easier than if every single warehouse had independent databases or no central DB at all;-).
