"I can confirm that in response to rising inflation and higher operational costs, we are increasing our commission rates for the first time in five years in certain European markets," a spokesperson said.
A notable exception is the British market, where Just Eat competes with Deliveroo and Uber's Uber Eats.
Just Eat's shares, which are down more than 60% this year, were 3.9% higher at 19.04 euros at 1155 GMT.
A spokesperson for Uber Eats in Germany said the company was "not planning any change in the service fee for restaurants at the moment."
A spokesperson for Deliveroo said the company could not comment but expects to later on Monday.
Germany's Delivery Hero, which owns a majority stake in Barcelona-headquartered food delivery company Glovo, could not immediately be reached for comment.
