A hotels and restaurants client working in People's Square had devices failing and holding up progress. We visited by appointment and handled them in groups, restoring normal use the same day and logging the devices into a table.
A bank branches client in Xintiandi had a device go down suddenly. We judged the fault direction by phone, and our technician brought matching parts and completed repair and testing the same day.
The client used to call only when something broke, and faults kept recurring. After asset records and scheduled inspections, the number of service calls dropped noticeably.
