All editions of ShowPro support Show Fees which are for example feed and bedding items, organization fees, campers, and really anything else you need to charge on a statement, show fees are completely configurable.
The Professional Edition of ShowPro supports Class Fees. These fees are associated with classes and are for example add fees, scratch fees, rode did not enter fees, jumper nomination fees, hunter/equitation fees, and a few other special purpose fees. These fees can be set to charge automatically and are a revenue enhancer for the horse show. These types of fees can be configured as show fees in the Standard and Lite Editions but class fees are a labor saving as well as a revenue enhancing feature.
