Having worked at GoDaddy whilst it was still owned and operated solely by Bob, he actually had tax accounting software he had written and was using in the mid-80s, early 90s. He sold this software (company et. al.) to Intuit. His software, along with many others in that field would eventually create the base of what would later become TurboTax.
Although QuickBooks was probably inspired by many features found in TurboTax, there is no clear line between the two, or any direct connections to Bob Parsons.
