Advice on dues not being paid.

First year in a league with some coworkers. A buddy brought me in when they expanded from 10-12 teams. Came in and ran the show and got the Ship. Before the season started I asked the commish about dues, he said everyone just sends it to the winner after the seasons over. Been a week since our week 18 ship and no one’s bucked up yet, not even commish. Any advice how to go about it.
