Working-capital is the metric

A factory can report record sales and still run short of cash if it pays steel suppliers in 15 days, holds inventory for 45 days, and gets paid by customers in 60 days. That timeline is the cash conversion cycle, and the standard formula is days inventory outstanding plus days sales outstanding minus days payable outstanding. (wallstreetprep.com) In manufacturing, the gap starts before the sale exists. Cash goes out for raw materials, labor, and work-in-progress inventory weeks before the finished part ships, and customer terms of 30, 60, or 90 days stretch the gap even further. (westportfinancial.com) That is why fast growth can make a factory feel poorer, not richer. Westport Financial notes that for a growing manufacturer, the working-capital gap often widens as revenue rises, because every new order pulls more cash into inventory and receivables before any cash comes back. (westportfinancial.com) The operating numbers that control this are simple. Days sales outstanding measures how long customers take to pay, days payable outstanding measures how long the factory takes to pay suppliers, and days inventory outstanding measures how long cash sits on shelves or on the shop floor. (jpmorgan.com) (corporatefinanceinstitute.com) When people in manufacturing talk about the supplier-buyer payment gap, they are usually pointing at one ugly combination: low days payable outstanding and high days sales outstanding. J.P. Morgan says those two measures are predictive of future cash flows, which is why treasury teams watch them as operating signals, not just accounting trivia. (jpmorgan.com) A low-margin order can make that gap worse even when the income statement looks fine. If a plant uses scarce machine hours on a job with thin contribution after freight, scrap, financing, and rework risk, it ties up capacity and cash for less return than a better order would have produced. (summa.consulting) (westportfinancial.com) That is why “more revenue” is often the wrong target on a crowded shop floor. If one customer wants 90-day terms and another pays in 30 days for the same machine time, the second order can be worth more to the business even at lower headline revenue because the cash comes back faster. (cfo.com) (jpmorgan.com) This also connects directly to free cash flow. The Securities and Exchange Commission says companies commonly present free cash flow as cash from operations minus capital expenditures, so when working capital absorbs cash through slower collections or higher inventory, cash from operations gets hit first. (sec.gov) Factories do have one obvious lever: push supplier terms out. Boston Consulting Group says extending payment terms can generate and preserve working capital, but it also warns that the tactic carries hidden costs if it damages supplier relationships or weakens the supply base. (bcg.com) So the hard-nosed version of the argument is not “grow slower.” It is “price, terms, and capacity have to clear a cash test,” because a manufacturer that says yes to every order can end up financing its customers, stressing its suppliers, and burning its best machine hours on business that looks bigger on paper than it feels in the bank.
