# Inventory tracking at Precision Components

# Inventory tracking at Precision Components

Precision Components Manufacturing is a composite company: a $28M medical device manufacturer. The workflow and the failure points are real patterns; the company and the numbers are illustrative.

## The problem

Inventory runs on spreadsheets across three warehouses. Production stops about 12 days a year for missing materials, at roughly $140,000 in lost revenue. Meanwhile $420,000 sits in excess stock, 15 percent above benchmark. Lot tracking is incomplete, and that is the part an FDA auditor cares about: medical device manufacturing requires full material traceability (ISO 13485, FDA 21 CFR Part 820, with the QMSR in force February 2026).

## The build

An inventory tracker on the firm's own systems. It watches consumption across the three warehouses and the CNC machines, forecasts demand from actual usage, and sets reorder points per part. Every receipt and issue writes to a lot record, so the question "which devices used this lot" answers in seconds. Ten weeks to build. The client's team spends about ten hours on it.

## The numbers it would have to hit

- Stockouts: 24 a year down to 2, a 92 percent cut
- Inventory accuracy: 85 percent up to 99.5
- Working capital freed: about $147,000
- Total annual savings at those numbers: roughly $372,000, mostly in recovered production revenue and rush-order premiums avoided
