The term "buyer" is what everyone refers to me as. Which is fine with me. However, that only gives a very narrow description of what I really do, which is provide monthly fincancials, research products, provide info on MBO's, etc. My voicemail greeting says "purchasing agent". Either way, I still fulfill the same function, which I think we all do in some form or another.
I am titled a "Pharmacy Purchasing Specialist" Some in our pharmacy say "purchaser" some say "buyer" it's about equal. But I agree with Dale, they have equal meaning.
My buyers title is Purchasing Agent. I am not sure she minds what she is called as long as she is a respected member of the team, which she is (very valuable to our efforts).
