I use a Mac, Ventura OS and want to upgrade to Sonoma, but every time I have upgraded in the past Quickbooks does not function

I absolutely cannot afford the QB online.   I cannot believe how much this costs.  The QB 2020 I purchased on sale at Best Buy for $300.

The $970 per year online is ridiculous.

When searching tonight I ran into a desktop QB that is reasonably priced: https://topquickbooks.us/quickbooks-desktop-enterprise-2024/

It is called TopQuickbooks and they call themselves an Intuit QB Partner.  Do you think this is legit?  I have been wondering what all the small businesses like me are doing to find an affordable system which keeps my old records intact.

 I refer to old QB transactions a few times a week and the only other alternative is to print out pages and pages of records gong back to the early 2000s
