What PDR Kalk can do

Hail & parking damage estimation

4 price matrices (VFFS, Zurich mixed-hail, BVAT with de-/remount column, Austria) with live calculation across 14 panels. Australia: hail estimate per panel, per vehicle, triage, or hours. Parking damage: per panel, flat rate, or time-based.

Documents & manual invoices

Cost estimate, report, invoice, Swiss QR invoice and ZUGFeRD/Factur-X e-invoice (PDF/A-3 with embedded XML) for Germany — all as PDF with your logo. Plus credit notes, assignment declaration, freeform manual invoices and a one-click job-package ZIP.

Insurance direct workflow

Guided 4-step process: damage entry, assignment declaration with digital signature, send to insurer, automatic split invoice — including in-person customer approval.

Subcontractor workflow

Encrypted job transfer (AES-256), three compensation models with live split, dual-notify close-out, and duplicate-merge on re-import — complete audit trail between contractor and sub.

Analytics dashboard

Business intelligence at a glance: revenue & cashflow, receivables by due-date bucket, top customers, top insurers, payment duration and a conversion funnel — multi-currency.

Multi-device & local data

Sync the office PC, the workshop tablet and the accountant's PC through your own NAS or cloud — same data on every device. Shared-folder sync runs on Windows; Android tablets work standalone with the full feature set. Stays 100% local, GDPR compliant, 4 languages.

What technicians say

Real feedback from PDR professionals

PDR Kalk ist für mich als PDR-Techniker eine enorme Arbeitserleichterung. Die Software ist übersichtlich, professionell aufgebaut und spart täglich viel Zeit bei der Kalkulation von Hagel- und Parkschäden. Besonders schätze ich die einfache Bedienung, die saubere Erstellung von Rapporten und Rechnungen sowie die zuverlässigen Berechnungen. Man merkt sofort, dass die Software von jemandem entwickelt wurde, der die PDR-Branche aus der Praxis kennt. Der Support ist schnell und kompetent. Klare Empfehlung für alle, die professionell und effizient arbeiten möchten.
