Custom payroll calculator
Give users a tool which allows them to calculate a custom monthly individual payroll total...allowing options to select specific games (by league), add custom fees (which may be earned externally) or deduct custom fees which may be deducted externally. This would allow members to accurately calculate fees earned and compare against external payroll processed.
As an example, in our association, schedulers/assignors earn a Assigning fee as a percentage of game fees that they schedule. Additionally, member officials are charged an operation fee as a percentage of their game fees.
