A growing manufacturer relied on manual, inconsistent processes with no automation or digital ordering, leading to shortages, uncontrolled consumption, and lost labor.

Our specialists mapped the operation onsite, then installed FMI technology, organized storage, and point-of-use inventory at the line.

Automation and point-of-use inventory improve customer and branch productivity while reducing consumption.
