Postmates has teamed up with Square to offer on-demand delivery to Square’s small business sellers. Square sellers now have the ability to offer deliveries that can be scheduled and tracked with the new Postmates integration.

“By partnering with Square to offer on-demand delivery, together we are enabling millions of small businesses to extend their reach and grow their business using our delivery platform,” said James Butts, SVP, product, Postmates. “Demand for Postmates Delivery as a Service has been growing quickly as all types of merchants look to add an on-demand delivery capability.”

With the new Postmates “Delivery as a Service” integration, restaurants and retailers can add on-demand delivery to any transaction with just a touch of a button. The stated goals are driving more revenue, increasing the reach of small businesses and scheduling future deliveries.

Postmates introduced Delivery as a Service in 2014, which allows businesses of all sizes to integrate into its platform from their own app or website. Postmates recently announced it expanded to a thousand additional cities, bringing the city total to more than 3,500 in the U.S., which is more than 70 percent of U.S. households.
