Product Engineering for Mietservice24

Equipment Rental Platform

The rental business that outgrew the phone, and started taking bookings in its sleep.

The Challenge

Lück Mietservice 24 rents heavy equipment (trucks with cranes, lifting platforms, trench cutters, and wood chippers) across Brandenburg, Germany. Every booking relied on phone calls during business hours, manual calendar checks, and hand-written WhatsApp confirmations. There was no online presence, no self-service, no structured records, and no way to prevent double-bookings.

Our Solution

We built a full-stack Next.js platform with an interactive calendar showing real-time availability from Supabase, a self-service booking flow with automated email confirmations via Resend, and one-click admin action links that eliminated all manual data entry. The platform also includes GDPR-compliant legal pages (Impressum, Datenschutz, AGB) required for German businesses.
