The distributor’s master formula: days of inventory on hand, plus days sales outstanding, minus days payable outstanding. A book that holds 60 days of stock, collects in 45, and pays suppliers in 30 is carrying 75 days of costs in cash at all times — and at a 75-day cycle, every $1M of annual cost of goods requires roughly $200K of permanent working capital just to exist. Growth multiplies it: the $45M food-and-beverage distributor in our case study ran a 90-plus-day cycle through seasonal spikes, which is exactly why the facility was sized at $3.2M across inventory and receivables together.
Importers carry a longer loop: deposits at order, balance at shipment, weeks on the water, customs — capital committed months before the goods can even be sold. That front end is a purchase order financing problem when it is against confirmed customer demand, and an inventory financing problem when it is a stock position; the full decision map is on the inventory and PO page.
Warehousing operations — 3PLs and distributors running fulfillment for others — share the receivables half of the cycle without owning the stock: their working capital problem is payroll and facilities against net-30-to-60 invoices, which points at receivables financing rather than inventory structures.
