I work for a company in purchasing. I have the opportunity to buy an item for 50$ less today versus doing a PO with a month delay in interest free payment. My concern is spending the companies money today versus the advantages of paying later.. what is the company's best option and why?
Can you give me a technical explanation.

Seriously?
I guess this is really your homework.
We'll gladly HELP but we won't do the work for you.
