Grubhub has collaborated with Block, parent company of the Cash App mobile payment service for peer-to-peer transfers that integrates Square's point-of-sale (POS) system with the food-delivery platform. Square is a Block brand.

The collaboration adds Block’s Cash App Pay as a checkout option for Grubhub customers.

Grubhub CEO Howard Migdal stated: "At Grubhub, we’re always looking for ways to help restaurants simplify operations and reach more diners.

"By integrating directly with Square’s point-of-sale system, we’re removing friction for restaurants so they can manage all their orders in one place, streamline kitchen workflows and keep menus up to date with ease. And with the addition of Cash App Pay, we’re giving diners even more flexibility and convenience at checkout — all while helping restaurants tap into a new audience of potential customers."

The deal allows restaurants using Square POS to receive Grubhub orders directly through their system, removing the requirement for additional tablets.

Restaurants will be able to manage menus, modifiers and inventory across channels from a single Square dashboard.

Orders can be routed directly to kitchen, and businesses can receive immediate payouts to help maintain cash flow.

Block sales and marketing global head Nick Molnar stated: "This partnership showcases Block's unique ability to drive value for both sellers and customers by serving both sides of the counter.

"By uniting Square’s operational capabilities with Cash App’s flexible payment technology, we’re creating a commerce ecosystem that benefits everyone, where restaurants can focus on delivering quality while giving customers more ways to pay."

In May 2025, HungerRush announced an integration between its POS system and Grubhub Marketplace.
