The best thing about this software is that it has all modules, which are needed for manufacturing companies like material requirement planning (MRP), production scheduling etc., so there's no need or room left out in MRP module alone! It can be used by both small as well large organizations with ease because everything you want comes along within one package without any hassle!! I would say nothing much if anything but just go ahead using them they're worth every penny spent.
Their support team works very fast when we have issues regarding their product itself; otherwise also good enough customer service provided through emails/phone calls helps me solve my queries quickly too :).
