Restaurants use Deliverect to keep track of orders from their own websites and a variety of apps, and to manage workflow and dispatching.
Under the deal, the two companies will integrate software and Deliverect will preferentially route deliveries via Uber Direct - Uber's 'white label', or unbranded, delivery service.
Financial terms were not disclosed.
External Delivery Service
This system is attractive to restaurants that want to highlight their own brand and control communications with customers, while being able to use an external delivery service.
Deliverect will benefit from improving its offering, while Uber will benefit from making additional deliveries, the companies' joint statement said.
Deliverect said it has 43,000 customers. The partnership will be available in the US, Canada, France, Germany, Britain, Spain, Portugal, Australia and New Zealand, the companies said.
Buybacks And Dividends
Uber Technologies announced earlier this month that it is considering buybacks and dividends to shareholders as its cash flow ramps up, CEO Dara Khosrowshahi said at an event on Thursday.
"We are now entering a phase where we are increasingly thinking about returning the capital to shareholders, either through dividends or buybacks, more likely with buybacks," Khosrowshahi said at the Goldman Sachs Communacopia + Technology conference.
Uber in August reported its first-ever operating profit of $326 million (€305.9 million) for the second quarter ended June.
It had more than $1 billion (€938 million) in free cash flow in the period.
