Building structure and topology at a glance
All devices, addresses and data points in plain text
Complete device list with manufacturer and type
Export for handover documents and maintenance records

Every integrator knows this pattern.

1

Project completed, invoice sent. Three days later: "What does this function do?" You explain. Again. And again.

2

Maintenance visit two years later. The client wants to know what's installed. You send a PDF, they don't understand it.

3

Referrals from satisfied clients? Rare, when clients feel like they don't understand their own system.

Your expertise lives in the .knxproj file. The problem: clients can't read it.

You work with powerful tools, built for experts. But after handover, your clients face a black box. Not because your work was poor, but because there was never a tool built for them.

Recommend venfree. Once. That's it.

Your client opens the project file in their browser. In seconds they see what you built, clearly, structured, visually. No ETS, no technical knowledge, no installation.

Before

Three worlds, three breaks

  1. 1

    ETS planning

    Click device after device in ETS, without ever knowing what it will cost in the end.

  2. 2

    Export the list

    Drag a PDF or CSV out of ETS. A second tool, a second context.

  3. 3

    Order from a wholesaler

    Fax, email or retype every part into an online shop.

With venfree

One process. One screen.

  • Plan without limits

    Plan your project as complex as you want, from a single room to a multi-family home.

  • Live price

    While you click, I calculate the street price live. No quote form, no waiting.

  • Your conditions, or even better

    Store your wholesaler conditions once. On every order I declare who I'm ordering for and pass your discounts along. Because I'm connected to multiple wholesalers, and every one of them offers different conditions per manufacturer. I find the best price live, often better than you'd get ordering on your own.

  • One-click ordering

    When you're done, order straight from the wholesale partner, without leaving the planner.

  • Best-price mix or single package, you choose

    Cheapest mix across multiple wholesalers for maximum savings. Or everything from one source in a single package if logistics matter more than the last few percent. Delivery to your door or straight to your customer's job site.

What your clients actually see.

Fewer support calls

Clients who can explore their system themselves call less. Every hour less support is an hour more for new projects.

Professional handover

"Just open venfree.de and upload the file." That's a different level than a printed PDF.

Satisfied clients

Clients who understand their system rate you better. And recommend you to others.

No effort for you

No setup, no account, no contract. You send a link. Done.

Project data stays local.

venfree processes project files locally in the client's browser. For saving and sign-in, encrypted transfer to our server in Germany takes place. Ideal for projects with sensitive address data.

Free. Forever.

No subscription, no license. Your clients pay nothing, not today, not tomorrow.
