Like many of you, I hate paying monthly for invoicing software when I send a handful of invoices a quarter. So I built a simple PDF invoice generator that runs 100% client-side — no sign-up, no monthly fee, works offline, and your client data never leaves your computer.

Try the free demo (no email required): invoice.jackgreen.top/app.html $9 one-time for unlimited use: invoice.jackgreen.top

Stack: plain HTML/CSS/JS + jsPDF. Would love your feedback — what’s missing?
