I like LAX88's post about getting bonuses on spend.
Depending on what your credit card programs are like and what you're trying to achieve; for instance, even with the free AMEX Hilton after $20,000 spend in a calendar year you'd receive Hilton gold status. You'd get at least 90,000 points @ 3x/$.
Same with the Palladium. At least 60k points, then you'd receive the 25k points.
AMEX SPG Business has 30k spend and you get gold with SPG. So you'd receive at least 30k points & gold status.
What is the CC processing fee? What cards do you have?
