The Challenge
Field engineers across 12 states used paper forms to document site visits, equipment inspections, and maintenance activities. Data entry in the office took 2–3 days post-visit, errors were frequent, and management had no real-time visibility. Engineers in remote areas had no internet connectivity during visits.
Our Solution
VFL Technologies built a .NET MAUI cross-platform mobile app (iOS + Android) with full offline capability using SQLite sync. Engineers complete digital inspection forms with photo capture, GPS tagging, barcode scanning, and digital signatures — all stored locally and synced to Azure SQL via Azure Mobile Apps SDK when connectivity is restored. Integration with Dynamics 365 Field Service provides work order management.
