Nigeria reached the knockout stages at the World Cup where they were eventually eliminated by England on penalties after a 0-0 draw in their last-16 match on Monday.
"FIFPRO can confirm it is assisting players in a disagreement with the Nigeria Football Federation concerning bonus payments, camp allowances and expenses, some of which date back to 2021," it said in a statement.
"During the World Cup, the players expressed the desire to remain focused on their performance without making public statements or facing other distractions.
"However, the Super Falcons believe that it is now time for the Nigeria Football Federation to honour their commitments and pay the outstanding amounts."
"The team is extremely frustrated that they have had to pursue the Nigeria Football Federation for these payments before and during the tournament and may have to continue doing so afterwards," FIFPRO added.
