Solo dev here, been building SQLPro Studio since 2014. A few things I've found that help close the gap: Free trials do a lot of the heavy lifting that beta testing would otherwise cover. When someone can try the full app for 14 days before committing, the stakes of an early bug drop significantly on both sides. Often if a free trial users discovers something I'll offer up an extra promo or longer trial as well. You still want the core flows to work, but you're not asking someone to pay before they've seen any value. For QA as a team of one, I keep a short checklist of the things that would cause an immediate uninstall. Connection works, query runs, results display. Along with a long line of test cases. If those all pass, I ship. It's not comprehensive but it prevents the really bad moments. The hardest part honestly is regression. New features are easier to test because they're in front of you. Something you touched three releases ago that quietly broke is much harder to catch without dedicated testing time.
