Built by Richard Bajnath, alongside window installers
Kozynofferte was founded in 2026 by Richard Bajnath in Amsterdam. I started this after watching too many window installation businesses fight Excel late at night — calculating VAT by hand, chasing customers for signatures, and losing quotes in email threads.
Kozynofferte is my answer: one workflow from measurement to balance payment, EU-VAT-correct out of the box, with e-signature and online payments built in. Not built for window installers — built with them.
What we stand for
Fair pricing
Monthly cancellable, no annual lock-in, no hidden upgrade nag. The price you see is what you pay.
Built for window installers
Not a generic CRM. Configurator, VAT logic and signature flow are designed for the niche from day one.
Data in EU
Hosted on Neon (eu-west) and Vercel. All data stays in the European Union. GDPR audit-export built in.
Open roadmap
We publish what we're building. Founding customers vote on what comes next.
