I bought Window Cleaner Pro once, smart when it worked but when it didn't what a pain in the backside having to rely on someone to sort it out. Never again rely on someone to use a window cleaning program, George works fine for a sole trader with customers who pay BACS, bank transfers. Takes minutes to block text everyone night before in one go.
I too wouldn't use cleaner planner but Awoka looks fine as it's basically an online version of George.
