Grubhub

Once the pioneer of online ordering, Grubhub now adds restaurants without permission and charges them commissions up to 30%, eating their entire profit margin. This high commission rate is 5% higher than #4 Postmates' typical fee, squeezing small businesses hardest. With a 40% surge in hidden fees over the past year, Grubhub's model is 25% less profitable for eateries than the industry average.
