Why generic quote tools don't work for window installers
Tools like Jobber, ServiceTitan or a generic quoting app are built for “the average contractor”. For a window installer that means daily workarounds: manually computing VAT reverse-charge, no frame-specific configurator, no e-signature adequate for a €8,000+ B2B approval, and no online down-payment integration. Your time goes into checking the quote, not making it.
Kozynofferte starts the other way around: we designed it together with window installers in pre-launch, and we deliberately chose not to include project planning, time tracking or purchasing. That belongs in Bouw7, AFAS, ServiceTitan or your own ERP. We do one thing well: from first customer contact to digitally signed approval with online down-payment in under an hour of work.
What's in our quote software?
- Visual frame configurator — 9 standard frame types (tilt-turn, sliding door, fixed glass, folding wall, etc.), choice of aluminium / uPVC / timber, all common RAL colours, double / triple / acoustic glass, security hardware. Live pricing as you configure.
- Branded PDF quote — your logo, colours, intro text and terms attached as appendix. On Professional+ connect a custom subdomain (quotes.yourcompany.com).
- Two-step e-signature — customer receives a unique link, opens the portal in your branding, signs with finger or mouse. Audit log with IP, timestamp and geolocation. Legally binding under EU eIDAS.
- Mollie iDEAL, SEPA & Bancontact — 30% down-payment at approval, balance after delivery. No separate payment requests anymore.
- EU VAT correct — reverse-charge for B2B customers with valid VAT-ID. Per-country VAT rates configurable. NL-specific 9% renovation rate for Dutch residential properties >2 years old.
- Customer portal with live status — customer sees progress from approval → production → delivery → installation. No more “how's it going” emails.
- AI photo analysis — take photos on-site, AI identifies existing dimensions and suggests an initial configuration. Saves 10-15 min per measurement.
