Where did my margin go?

When you're reviewing factory bids for a new production run, it's tempting to fall in love with the lowest unit price on paper.

An example

Factory A quotes $14.50 per unit. Factory B quotes $11.20 per unit.

On a 20,000-unit run, that's a $66,000 difference. The decision feels easy. You sign with Factory B, work out a projected 65% gross margin, and feel good about your unit economics.

Fast-forward six months:

• The factory used a lower-grade alloy that caused a 12% scrap rate during assembly.
• The packaging dimensions were off by 1.5 inches, creating dead space in shipping containers and pushing ocean freight up 18%.
• The factory missed the shipping window, so you paid air express to hit holiday retail deadlines.

When the dust settles, your real landed cost isn't $11.20 per unit. It's $16.80. Your 65% gross margin drops to 42%, and your cash flow takes the hit.

The hidden cost of "cheap"

A quote only tells you what a factory wants to charge under perfect conditions. It tells you nothing about scrap rates, yield loss, material substitution or packing efficiency.

Real cost reduction doesn't come from beating a factory down on price until it cuts corners to survive. It happens on the ground:

• Checking bill-of-materials (BOM) cost sheets line by line for hidden markups.
• Getting master carton packing right so you're not paying to ship air.
• Catching tooling defects before thousands of parts are ruined.

The cheapest quote on paper is almost never the lowest cost at your warehouse door.
