Inventory Turnover Ratio: Explanation + Calculation

Month-end billing at a 3PL is a reconciliation exercise: what did the warehouse actually do for each client, and does the invoice say the same thing? When those two answers drift apart, you either overbill a client and spend the next week rebuilding trust, or you underbill and quietly give away work you already performed. 3PL billing accuracy is the discipline of closing that gap, and it has more impact on margin than almost any other back-office process in your operation.
