When the money collected does not match the fee

The OpenSports captain FAQ says that missing the payment deadline is up to the league admins, who reserve the right to charge the captain’s card or invoice the remaining balance. It says an overpay shows up as a negative team balance, and refunds are up to those same admins. It also says that if an admin refunds a player, the captain has to make up that balance.

This calculator does not charge a card and does not send an invoice. It shows the gap instead. Paid minus owed is a credit when someone has paid too much, and an unpaid or part-paid balance when they have not paid enough. Credits are listed on their own so they do not hide someone else’s unpaid amount.

If fixed substitute amounts add up to more than the league fee, the split stops and names the extra cents. It does not invent negative shares for the rest of the roster.
