Case Study: WR-Maintenando achieves digital inspections and streamlined operations with AppSheet

German Maintenance Specialist Builds Apps to Modernize Management

WR‑Maintenando, a German specialist in window and sun‑protection maintenance for large commercial buildings, handled up to 3,000 projects a year using paper forms, which forced staff to manually transcribe handwritten notes into spreadsheets. As projects scaled (100–4,000 windows per customer) the backend workload and error rate became unmanageable, prompting the company to find a way to digitize inspections without hiring developers.

They adopted AppSheet for no‑code app building, creating project‑specific apps that link directly to their spreadsheets and use references, conditional fields, searchable defect lists and scheduling features. The new apps let technicians enter detailed inspection data and photos on site, cut data‑entry errors, speed reporting, improve customer transparency and satisfaction, and make office work faster and less error‑prone.
