Over 9,000 Subway restaurants in the US are now offering a delivery service, announcing new partnerships with UberEats, GrubHub, DoorDash and Postmates. The move is part of an overall shift in the company to improve sales for franchisees, and will start “in the coming months.”

“We want to connect with consumers and give them the convenience of choice, whether it’s a customized, made-to-order sandwich or in how they get their meals,” said Michael Lang, Subway’s senior director of global convenience.

Subway is the first of the major fast-food chains to spread its delivery services across all the major platforms. Most chains have stuck with one or two, such as McDonald’s partnering with UberEats while KFC and Taco Bell work with GrubHub – with Yum! Brands going so far as to take a $200 million stake in the delivery company.

According to research firm Technomic, delivery is expected in grow 12 percent a year for the next five years.
