Client abhors 'subscriptions'

A long term client (signed on with office of 17, now down to 1.5 uses), hates subscriptions. Lawfirm. Has been using QB. Intuit is sending messages about QB being terminated and unable to purchase. Pushing for QBO subscriptions.

Client has asked for an alternative to QB that is not an online subscription.

As a JOKE I sent him to look at GnuCash. And he LOVED it. I should have known, he uses an HP calculator with RPN. His only request is for a more usable interface.

Does anyone have any recommendations for similar tool to GnuCash that is 'prettier' and easier for his 20 something daughter/bookkeeper to use?
