In a letter to investors before its share price plunged last week, online food delivery service GrubHub Inc cited its profitable ties with small and medium-sized restaurants, saying they generate 80% of the orders on its platform.
"This is a highly lucrative relationship for both parties," the letter said.
But some restaurants think otherwise and have begun pushing back against what they see as the relationship's unfair distribution of profits.
A growing number of small and mid-sized food chains want to reduce ordering and delivery commissions as high as 30% charged by the big four third-party platforms - GrubHub, Uber Technologies Inc's Uber Eats, DoorDash Inc and Postmates Inc, industry sources say.
"They hate the relationship and they are getting raked over the coals," said Ben Gaddis, president of T3, a digital marketing and tech consultant to restaurants such as Pizza Hut and Schlotzsky's. "The smaller they are, the more it impacts their margins."
The delivery platforms charge restaurants for having their menus listed on their sites, which customers can use to place orders - similar to the way consumers book hotel rooms through third-party online marketplaces like Priceline, Kayak or Expedia . Restaurants pay higher fees if they want to be listed more prominently, or if they use the services to deliver the orders placed through them.
"They've become this necessary evil," said Bareburger Group Chief Executive Euripides Pelekanos, referring to the delivery platforms. The organic burger chain with 46 stores mostly in the northeast hopes to be rid of all third-party platforms by 2020.
In 2017, Bareburger booked $20 million in revenue from orders placed through third-party platforms, Pelekanos said, but it also spent about $2.5 million to $3 million in related fees.
