Hey i have been looking for a specific app and havn't been able to find what i was looking for yet. I am a professional tennis instructor and was looking for an app that i could use to manage the lessons i give and the rates and things like that. What im looking for - entry of clients - entry of payment - sales - link with iCal possibly? - viewing monthly and weekly reports of money brought it -etc. Does anything like this exist!?!?!?!? thanks so much in advance.
