The way fuel surcharges are billed to some of these customers would make you think the Three Stooges devised it all. One FSC for a van, another for a truck, everyone understands that, but some (many) customers have different fuel surcharges for weights, dimensions, where picked up, where delivered, time of day picked up or delivered, even different routing affects things with many customers. There are some who have one surcharge from a shipper to a consignee, and a different FSC from the same shipper if it goes to a different consignee.
It's nuts, and that's why the FSC is just an estimate when it's quoted in the load offer. Panther may do a lot of things that may or may not be questionable, but I do know, FOR SURE, that they do not play with the FSC. Whatever the customer pays, they pass it along, 100%, to the contractor.
The problems come when there is a bad quote, because someone picked the wrong FSC code, or there was a mistake in who the paying party was, a lot of reasons. It gets more complicated when the (alleged) purpose of the Load Receipt is the "We Pay What We Say" mantra, when, in fact, they don't in many cases. The Load Receipt has a disclaimer wide enough to drive an 18-wheeler through, yet "We Pay What We Say". Keep chanting it.
My answer to the reasons for the misquotes is quit making quoting mistakes, or Pay What You Say, I don't care which.
Now, understanding how the FSC works, in that it's yer basic complicated mess, I can forgive the actual paid-out FSC being off a little, even though quite honestly I shouldn't have to. It usually is off a little, but usually within a penny, two at most. It's when it's off by a nickel or more that I have a problem. If they are going to alter the agreed-to-terms to that degree, a simple phone call explaining it would certainly help ease the pistoffedness.
I do keep track of it weekly, monthly, and YTD, as each week the paid-out FSC will be different. More often than not, it's within a penny higher than what was quoted. Sometimes it pays out at significantly more than what was quoted. My most recent settlement includes one that was quoted at $.40, and paid at exactly $.40. That's rare. Another one was quoted at 41 cents and paid at 41.79 cents, which is about the normal amount of variation, but yet another was quoted at 52 cents and paid at 58.65 cents. That one makes up for the one the previous week where I was shorted a nickel.
To date I'm in the black on the FSC over/under. So while the significant shortages do stand out and can make one mad, in the long run you're probably making out better than you think you are.
