how come you prefer Manager.io over wave?

I still prefer to store my core financial data locally rather than cloud-based applications (e.g. Wave). Another problem is that Wave stopped its service in most countries several years ago. I want to reduce the headache for clients when they stop their services completely in the US. You could learn about the difficulties when GoDaady Bookkeeing discontinued its service last year. You need to incur costs to convert data to other programs.
