Rate Types

A rate type is a unit amount that is multiplied by the weight, volume, or other factor to calculate the total charge. The multiplier is the rate basis. Each rate has a rate type that defines the rate. Each rate type must also specify the level at which a rate is applied. A rate can be applied at the shipment or load level, detail level, or piece level. The system provides these rate types:

Rate Type	Description
Unit amount	The amount charged that is specified by the rate basis. Depending on the rate basis, a unit of measure might also be required. For example, if the rate basis is weight, then the unit of measure must be specified.
Stored in route.	The amount charged, which may be based on a unit amount or a fixed amount, is stored in the route. For example, carriers charge truckload rates based on number of miles. When the rate per mile changes, you can update the route with the new rate.
Fixed amount	The amount charged regardless of weight or volume. For example, a parcel carrier charges a flat rate for a package. In this case, no rate basis is required.
Prorated amount	An amount that calculates one or more billable charges by prorating a payable charge based on volume or weight.
Business Function Exit	The Business Function Exit rate type enables you to use a custom business function to calculate rates or to access third-party rating products.
