I'm switching to Wave cloud accounting software because it is the same as what I am paying $40 a month for, but it is free. I was willing to pay $15 or $20 per month

It is a good product for a startup business or for anyone who needs to cut their cost. It is not surprised we struggle to find any 3rd party reliable app to integrate with it. Contact us should you need a 3rd party migration service in the future. 

QuickBooks is better than Wave. Wave accounting is not desktop software and comes up with many complications. Also, the number of integrations possible in QuickBooks is relatively high as compared to Wave. Also, hosting the QB desktop on cloud servers of any Intuit authorized hosting provider will be the best solution, in my opinion. The investment is more than Wave, but the ease it offers to life without much hassles is worth it. You will get a plethora of accounting features and cloud benefits in one.
