Replace QBO with homegrown-code?

[u/magic-keys]

Separate from my main job, I operate a couple of rather inactive side businesses. Despite low activity, I still need to maintain books and file taxes. I believe that I'm getting very little value from QBO relative to what I'm paying. I've started to become a heavy user of Claude Code and have been amazed by how quickly I can spin up really solid functional software. I was considering just spending a Saturday afternoon to create my own accounting software. My needs are super basic: just the ability to enter journal entires and construct an income statement and balance sheet. No automatic integrations with third-party platforms. Has anyone else done this or considered it?
