Yeah, the GnuCash business workflow seems a crazy complicated manual
process coming from QuickBooks where even livestock inventory is seamless. My
business cash accounting workflow might affect my view. I never import bank
transactions into QuickBooks but that is how I enter data into Gnucash.

You could try importing a couple of QuickBooks transactions into GnuCash.
The text fields are fairly logical in Quickbooks but there is no
convention in GnuCash. Maybe some sort of keystroke macro can step through
parts of the process.
