Uber Eats is available in more areas making it a bit easier for drivers to start making deliveries. Additionally, if you are already an Uber driver, signing up for Uber Eats takes minimal effort. Uber Eats vs DoorDash: Earnings Uber Eats Earnings Each time an Uber Eats driver drops off an order they get paid.

For example, in some areas, there is a guaranteed minimum per hour. Meaning that if you do not make at least the minimum rate, DoorDash will pay the difference. To make being a Dasher even sweeter, DoorDash only takes a 20% commission on average.

Dash Now makes it easier for drivers to reduce downtime between auto-scheduled deliveries.
