Custom Development Real Estate

Digitizing Property Rental & Invoicing in Germany

How Lambda Logics helped monteurzimmerKing GmbH replace manual bookings and invoicing with a real-time platform built to scale across franchise partners.

Client: monteurzimmerKing GmbH · Live since May 2023 · ~200 bookings/month

The Challenge

  • ›Bookings and invoicing tracked by hand, with no central system
  • ›Frequent double bookings across properties
  • ›No online presence for nearby construction companies to find available properties
  • ›Franchise partners had no shared visibility into inventory

Project Goals

  • ›Centralized dashboard with a real-time booking calendar
  • ›Search properties within a radius of the job site
  • ›Automated invoicing, including cancellation handling for non-payment
  • ›Clean scalability as new franchise partners join
  • ›Rich property data: capacity, facilities, inventory, seasonal rates
