Why I see my client $75 with Rover fees will be deducted from this amount, when Rover charges more?

Rover takes 20% of your earnings (just guessing because it does depend on when you started with Rover and whether you are RoverGo, which is 25%).

The additional amount $5.25 is a service fee that Rover charges each customer directly. it is between 5-7% of the booking but no more than $25.
