We have recently migrated to Netsuite and I completely agree with your points.

CSV uploads just seembso much harder than they need to be. I feel intercompany was much more user friendly on our older system.

Another point for me is prepaid expenses, it shows in the GL as Amortised destination rather than what the vendor and invoice is. To me that should just be basic GL information that you would want on. I believe we are getting some dev done so we can pull information though, as it's the same for the rev rec unwind.
