A $20/year invoicing tool for solo developers (simple, fast, no bloat)

Hi HN! I built a super lightweight invoicing platform for solo developers, freelancers, and one-person businesses. Most invoicing software costs $20–$40/month and is packed with features you don’t need. Mine is $20/year and focuses on the essentials:• Create invoices in seconds • Send invoices by email • Automatic email reminders • Recurring invoices • Simple dashboard for paid/unpaid tracking • No team features, no CRM, no bloatI built this because I freelance occasionally, and every invoicing tool I tried either felt bloated, overly enterprisey, or was way too expensive for solo work. I wanted something simple that didn’t require a “plan,” onboarding flow, or learning curve.A few things people have asked so far: • No lock-in — you can export your invoices anytime • No limits on the number of invoices • No weird pricing tiers or upsells • Works well on mobile • You own your customer list (I don’t touch it)Here’s what I’m looking for from HN: • Brutally honest feedback • Any missing “must-have” features for solo entrepreneurs • Performance/UX suggestions • Security concerns I should address early • Whether the $20/year model feels rightIf anyone here freelances or runs side projects, I’d love to know what your current invoicing workflow looks like and what annoys you about existing tools.Thanks for reading — happy to answer every question!
