Fees are disbursed by the winery, and paid to someone other than the grower. The cost may be borne by the winery, its grower, or shared by the two parties. Fees are relative to tons received or the dollar value of the contract. Their units of measure are $ per ton, or percent of contract dollars.
There are two steps to using fees with your grape contracts.

Applying Fees to Contracts

On the Grape Contract Maintenance - Pricing and Payments screen we'll select the fees that apply to the contract. 

Select fees using the check boxes (large arrow). Fees associated with the contract will be calculated and will appear in the Contract Totals summary (smaller arrows, above).
