What technicians say

Real feedback from PDR professionals

As a PDR technician, PDR Kalk makes my work enormously easier. The software is clear, professionally structured and saves a lot of time every day when calculating hail and parking damage. I particularly appreciate the simple operation, the clean creation of reports and invoices, and the reliable calculations. You can tell immediately that it was developed by someone who knows the PDR trade from hands-on experience. Support is fast and competent. A clear recommendation for anyone who wants to work professionally and efficiently.

Florian HuberCarrosserie Huber · Aber Tip TopSwitzerland

In my view, PDR Kalk is the best hail and parking damage calculation software on the market. It impresses with extremely simple, intuitive operation and is available for both Windows and Android — ideal for flexible use in the office and on the road. Calculations can be created quickly and clearly, sent digitally straight away and seamlessly converted into invoices. A particular strength is the ability to cleanly divide work and let several technicians work together as subcontractors in one system, keeping full transparency over services, billing and responsibilities at all times. PDR Kalk saves an enormous amount of time, reduces errors and ensures a professional, structured workflow — from damage assessment to billing. For hail and parking damage businesses it's a real asset and hard to work without. A clear recommendation.

This professional calculation app helps businesses estimate parking and hail damage on vehicles quickly, precisely and without fuss. It impresses with its particularly simple operation and enables efficient damage capture. Stored lists of various insurers make processing even easier and ensure a structured, practical workflow. Thanks to pre-stored items, calculations can be created quickly and tailored individually, and you can add your own notes for special requirements. The result is a mature, professional product that reliably and effectively supports digital damage calculation.
