How it works

From inquiry to signature in four steps

From first click to sent quote: in minutes, not hours.

  1. 01

    Configure window

    Pick type, size, material and glass. Price calculates itself. Save as draft in seconds.

  2. 02

    Send quote

    One click generates a PDF in your branding plus a unique customer portal link, with intro email.

  3. 03

    Approval and measurement

    Customer signs online. You plan the measurement. After surveying, the quote auto-updates and is re-signed.

  4. 04

    Payment & delivery

    Down-payment via iDEAL/SEPA on approval, balance after delivery. Status auto-flows: production → delivered → completed.

  • Custom intro text and terms & conditions
  • Branding visible in customer portal too
  • Custom domain via CNAME — Pro and above

A personal note

“I'm building this because I miss it in the market myself.”

Hi — I'm Richard Bajnath, founder of Kozynofferte. I've watched window installers spend evenings hand-crafting Excel quotes with prices that don't add up and proposals lost in email threads. Kozynofferte is my answer: one workflow, EU-VAT-correct, e-signature and online payments — built with window installers, not for them.

Every customer gets a direct line to me personally and a say in the roadmap. Try it free for 14 days and tell me what you think.

Frequently asked questions

Everything you might want to know

What is Kozynofferte?
Kozynofferte is quote software built specifically for window installation and fenestration businesses. It includes a visual configurator (frame type, material, glass, hardware), branded PDF quotes, two-step e-signature, online payment via iDEAL/SEPA, and a customer portal — all in one workflow.
Is it only available in the Netherlands?
The Dutch market is our home base because of our deep VAT-reverse-charge and 9% renovation rate logic. We are opening up to EN customers in EU/UK/IE with adjusted positioning. For non-NL companies: VAT-handling needs to be configured manually for your jurisdiction.
How much does it cost?
Starter €49/mo for 25 quotes, Pro €149/mo for 150 quotes, Business €349/mo unlimited. Enterprise with custom SLA and integrations on request. All prices excl. 21% VAT, monthly cancellable. 14-day free trial, no credit card.
Can my customers e-sign quotes online?
Yes. Two-step e-signature is built in — customers receive a unique link, open the customer portal in your branding, sign with finger or mouse on phone or desktop. Audit log includes IP, timestamp and geolocation. Legally binding under EU eIDAS.
Can I import my existing customer list?
Yes — via CSV. Customers, products and price lists are imported in minutes. For larger migrations (>500 records) Richard helps personally in a free onboarding call.
