Henry Camp, CEO, explains: “Let me give you a glimpse of what we do. For one of our major clients, in our first pass at only a small part of their supply chain, we found $8 million dollars of net profits and pulled $42 million of cash out of inventory. Last time we got together, we explored further opportunities with the top management. We all agreed that there is an additional 12% of sales that can drop to the bottom line and cash equivalent to 8% of sales. For them, that is around $300 million of cash flow. Now, they agreed that those numbers are only possible if we address core challenges of their supply chain, not just symptoms.
