Check out Manager.IO. Free for desktop use (full operation, no ads, no limits, no b.s.). Full featured (comparing well with what I remember about AccountEdge), moderately customizable, full array of reporting, project-inventory-time invoicing, very fast, stable and reliable so far. The support forums are active, generally friendly, and the developers very responsive.
I run my equestrian facility, and my own graphics/photo studio in Manager. The quality overall is surprisingly good. Well worth putting up with a few petty feature niggles.
Local apps for Mac (all OSs for the last decade), Windows and Linux. Files are totally cross platform.
Manager Does NOT do payroll (which is fine, I'm sole LLC). It does NOT directly plug into Tax submission apps (which is fine, because in livestock agriculture + land use, I got a tax guy who starts with my standard reports.)
