Finding loads
One of the 1st things you must do is open an account with link logistics.
All you need is the basic account without all the frills. do not go for DAT , mileage and credit reference.
You can get all of those for free and more up to date.
All the americans Carriers and brokers can see you on link anyway, and why pay to see them with only a few trucks.
For mileage, you should have a recent version of PC miler, again you do not need the frills such as Streets., you can use microsoft streets for more detail.
You or your driver should always call the consignee or shipper before getting there to do two things.
1) To see if the freight is ready and that it is what you contracted for.
2) To get directions, none of the mapping software is precise enough to give you street closures and adequate low bridge info.
As for increasing sales, other coleagues have stated it already. You must work closely with good freight brokers ( most of them are) and good carriers.
Most importantly, be professional.
Do what you say you will do and advise all customers of any delay's or issues that affect the delivery of the freight.
Work out your costs as soon as possible, it is verry difficult to do , but without it you may realize you are losing money and it will be too late to turn things around.
