I do work for a few Clubs and Non Profits, and about the same time they have all decided they want to review their Point of Sale, CRM, and Accounting Packages to find a better way to work. Some of them have a restaurant and or bar, so inventory management might be nice too.

I was after some feedback from others as to what you have seen works well, maybe something around costs, and whether the platform of choice has good support. 

I am happy if it's not all one product, but reasonable integration would be considered an obvious plus.

Happy to consider any recommendation, though would prefer on premise.
