Maybe you focus on shipping and transporting refrigerated food items to warehouses and supermarkets, or perhaps your main goal is the electronic industry, or the truck battery manufacturer near you!
Perhaps you focus on shipping packages for online retailers or you want to do a business with intermodal companies only.
Regardless your choice of clients, you need to know few things up front like: do you seek a many smaller organizations or small number of large customers for your logistic business?
Furthermore, you should define who your primary market is, as well as if you are going to have any secondary markets.
When mapping out your marketing and sales strategies, keep in mind that your target market is basically every one or, at least everyone that have cause to move things from one location to another location.
