Inventory Performance is part of Inventory Truth & True Cost in Windward System Five. System Five includes 5 documented capabilities here — all 5 in the standard set.
These 5 capabilities sit within System Five's 1287-capability documented set — a selection, not a ceiling.
Know which stock earns its shelf space
Reports sales, margin, cost of sales, average inventory level at landed cost, stock turns and GMROI, summarised by main category, sub-category, supplier, brand or item, with a graph tab. Margin is (sales minus cost of sales) divided by sales; turns are cost of sales divided by average inventory level.
See demand and what is still coming
Product Demand reports demand over a range of book months by category, supplier and department; the Delivery Report shows delivery status over the same month range for a range of categories and suppliers, both with an include-returns option.
See which sizes and colours sell
Reports sales for items that share a part number but differ by size, colour or weight, searched from the Part Find window's Matrix tab and displayed as a size-by-style grid for a date range.
Know our best-selling lines by units
Ranks items by units sold from a start date over a set number of complete weeks, with the option to include items with no sales and to cap the list at the top N. Partial weeks are excluded so averages are not distorted.
See how many weeks of stock remain
Shows a configurable number of complete weeks with weekly average units and dollars, weeks of supply based on calculated unit sales per week, available quantity and cost, committed quantity and stock on order, filtered by supplier, category and department.
