The big tier ones (Bosch, Continental, etc) insist on payment up front specifically to avoid this. It's the smaller vendors that don't have leverage to set payment terms who get screwed.

One tactic I've seen OEMs use is to buy for multiple products and stop payments for one as a test. If the vendor complains, they lose all the unrelated business (possibly including clawbacks!) and the OEM moves to the second source. This can kill the supplier.

The winning move is not to play.
