One thing that I have found out with being new is your credit rating on the load boards. It can take 6 months to a year before you have any type of credit rating at all. Several carriers will not even look at your load. Doesn't mean they won't haul for you but you have to do the extra work and call them and tell them what you have to offer. Also realize if you are calling them to get the load covered they know you need to get it moved and will want more for the load. So you need to be able to work something out with them.
As long as your credit score is approved and or you pay the majority of the load rate upfront once loaded..you should be ok until you become more established......the difference for a new carrier is , the new carrier assumes all of the risk once he/she signs that b.o.l.....YOU,the broker is pretty much in the clear for the entire trip until the load is delivered with no os&d......Brokers come and go quickly ,oftentimes leaving carriers on the hook for large sums of cash.
My deal with new brokers is 50% upon pick up, and 50% before unloading at delivery.
If being a new carrier means no one wants to work with you and you have to haul for cheap just to get rolling and all the hardships some guys go through, well same with brokers.I don't work with anyone below B credit.
