ZPify is a tool built for freelancers (ZZP'ers) in the Netherlands to take control of their finances. Our mission is to simplify tax estimation and invoicing so you can focus on your work — not on spreadsheets. Your invoice data stays in your browser. We never share or sell your personal information.

ey Product Hunt! 👋 I built ZZPify because I was a freelancer in the Netherlands and had no idea what I actually kept after taxes. Every tool I found was either an ugly government PDF or a €50/month SaaS with features I didn't need. So I built the simplest version: enter your hourly rate → instantly see your net monthly income, how much to save for tax, and your effective hourly rate. Then create a BTW invoice and download it as PDF. 🎁 Launch offer: Everyone who signs up today gets permanent free access — no payment ever. You become a founder. I'd love your feedback: What's missing? What would make you actually use this weekly? Try it at zzpify.nl and let me know what you think 🙏
