What most employees do not realize is that corporate rebates and incentives are enacted when the employee population reaches thresholds outlined in their vendor contracts. Meaning, while an employee thinks the actual cost of his or her airline ticket is $500, the actual cost may be much less. And in most cases preferred supplier contracts contain volume commitments that, if not met, could jeopardize an entire contract and cost the company millions in lost discounts based on non-performance. This is precisely why compliance with preferred vendors and contracted rates is critical. Jeff Pulver
