The commission stack
DoorDash lists 15, 25 or 30 percent per delivery order plus 6 percent on pickup (DoorDash, 2026). Owners in the forums report 28 to 33 percent after promos. Some ordering vendors add $2 or $3 per order on top of a monthly fee. A direct order through your own site pays none of that.
App orders a month, times your average ticket, times the commission you pay.
