Built alongside window installers
Kozynofferte started in 2026 in Rotterdam, after watching too many window installation businesses fight Excel late at night — working out VAT by hand, chasing customers for signatures, and losing quotes in email threads.
Kozynofferte is our answer: one workflow from measurement to quote approval, with Dutch VAT scenarios, e-signature and staged payment instructions 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 Europe
App hosting on Vercel (Frankfurt, EU); database on Neon (London, UK) under the EU adequacy decision, with migration to an EU region planned. GDPR audit-export built in.
Open roadmap
We publish what we're building. Customers vote on what comes next.
