Built a free invoice generator solo — would love brutally honest feedback

Hey everyone — I launched MineInvo (a free, no-signup invoice generator: mineinvo.pages.dev) and I'd genuinely appreciate some outside eyes on it before I keep building.

A few specific things I'm unsure about:

• Is the flow from "open the page" to "download a finished invoice" actually fast/clear, or does anything feel confusing?

• Are the invoice templates good enough, or does it need more variety?

• Anything missing that you'd expect from an invoice tool but don't see?

• Any bugs — I've tested it myself a lot, but a second pair of eyes always catches things I miss

I'm not trying to build the next big SaaS here — just a genuinely useful free tool, so real critical feedback is way more valuable to me than "looks great!" 🙏
