Say their profit margin is 1%. If you offer to pay them a 1% higher price, you're offering to nearly double their profits on whatever they sell to you.

Admittedly, that only works if you are a sufficiently large portion of their business. If you're a tiny percentage, then it may take a lot more to motivate them if their other customers aren't willing to pay more.

If the solution to the problem involves line checks, independent audits, personnel checks, increased pay, etc., thenyes, throwing money at the problem is a large part of the solution.
