A DTC home goods brand spends six weeks working through samples with a manufacturer in China. The factory finally signs off: 5,000 units of a redesigned kettle at $4.10 a unit, a price that only holds at that volume. The brand's bank balance covers about 2,800 units at that rate, so the founder does the sensible-sounding thing and asks the factory to cut the order to match the cash on hand.
The factory sends back a new quote. Below 5,000 units, the price is $5.35 a unit, not $4.10. The brand ends up paying more per unit for a smaller run, and still has to cover a $6,000 deposit on that smaller order out of the same limited cash. A decision made to be careful with money costs more per unit and delivers fewer units to sell.
This isn't a rare misstep. It's how factory pricing works, and most brands only find out the way this founder did: mid-negotiation, after the number they thought they'd locked in moved.
