In addition to the setup categories we have discussed so far, there are a few more topics that are sometimes not looked at until after installation but that you may want to consider prior to setup.
Shipping Methods are company specific and are used to define all the possible shipping options a company uses to deliver goods to customers or receive goods from vendors. During the Dynamics GP installation a default list of shipping methods can be installed.
The two major functions of shipping methods are to communicate the shipping information to employees, customers, and vendors on transactions and documents, and to determine what taxes are calculated automatically by Dynamics GP. For example, if the shipping method on a customer invoice has a type of Delivery, then the customer's shipping address will determine the tax. If the shipping method has a type of Pickup, then your company's warehouse location will determine the tax.
