Following each modular unit from parts readiness through build and test to a signed installation.

The challenge

Each unit is assembled from many components held across the warehouse and in sub-assemblies, then installed on site. Without one record, nobody could say at a glance which units lacked parts, which stage each had reached, or what was still to be checked on site.

A unit cannot be built until every part is there, and it cannot be handed over until every stage is signed.

The solution

Every unit is one record: its components, its five stages from frame to final check, and a timestamped log. Stock is tied to projects, so a unit shows what it is waiting for before the workshop starts. The same record then goes to site behind a QR code, where the technician works through the steps and signs each one off.
