Too Complicated

First joining up I figured it was a collection of "apps". I had no idea there were tables and fields that are custom put together (like an MS Access app) to build these.(i.e. I had no idea of the back-end side). Once I figure this out, I had no idea how the controls where linked with fields, and tables, etc., so had no idea, without trial and error, what was what, nor (even after searching help) the relationship between controls, fields, tables, forms, etc., nor how to modify the form fields, html, etc. On top of this, there's no *clear* way to move the data between this and Quickbooks Online, so I gave up. I have no time to "hunt" for this basic info that should be easily found inline with the system. The "canned" apps never do it all well, and usually need customizing, and having issues with it will only hurt the products success.
