Inventory measures are read from the daily stock snapshot — the record of what was on hand, product by product and warehouse by warehouse, at each day's close — so they are positions, not flows.
- Stock value — quantity on hand multiplied by the moving-average unit cost, summed: what the shelves are worth, at cost, on the snapshot date.
- On-hand, committed and on-order quantities — what is physically there, what is promised out to open orders, and what is on its way in on open purchase and work orders.
- Aging bands — on-hand quantity grouped by how long it has been there: 0–30 days since receipt, and so on up to 90-plus. Old stock is a fact here, not an anecdote.
- Movements — the period's flow through the warehouse: quantities in, quantities out (shown as a positive amount of leaving), the net change, and the value of those movements.
- Turnover — trailing twelve months of cost of goods divided by the average stock value across the same window: how many times a year your stock value turns over. Where a company has no stock history yet, turnover shows nothing rather than a confident zero — a ratio over nothing is not zero.
- Days of supply — on-hand divided by the current average daily demand, per product: how long the shelf lasts at the rate things are leaving.
- Dead-stock value — the snapshot value of stock with no outward movement inside the idle window (180 days by default).
- Stockout count and below-reorder count — how many product-and-warehouse pairs are out of stock while demand is open against them, and how many sit below their effective reorder point.
- Planning values — reorder point, safety stock, lead time, average daily demand and ABC class ride along per product-and-warehouse as reference data. They are read per pair and never totalled; a sum of reorder points would mean nothing.
