"There are many ERP's available in the market but none is the wonder solution that clicks on all facets and that's why I would suggest you to look beyond the traditional systems as they have a very complicated structure and are not at all user friendly. The systems with complete functionalities are very expensive and others they just lack value.

Instead of banging your head on the same door which won't answer your call, try S.I.M.P.L.E (strategy, integration, management, productivity, longevity, and economy) a product by Dexciss. It has all the features you mentioned above and in fact has a lot more. It's a complete enterprise system with an easy and attractive UI and the best part it's not at all expensive. It's web based, open source, and works fantastically well."
