I built a Home Inventory software back in 2006 called Attic Manager: https://guacosoft.com/attic/ In the first few years it only sold a couple of copies per quarter, but then Intuit decided to discontinue support for their Quicken Home Inventory programs and users got stuck. I added the ability to import that data and then the sales started doing well. It has tapered off in the past three years but I still get some months over 00 during the year. I haven’t really done any marketing, as it’s just a Home Inventory program I made for myself, to keep track of stuff when we were moving to a new home. As far as I know, Attic Manager is still the only program which can load QHI data.
