how is the payment processed? when booking what amount the stay is charged and when is final payment charged?

When the sitter accepts the job, you will have to pay for it in full to be considered a confirmed booking. Payment is not done in installments. However, Rover holds the funds until 48 hours after the job is completed to ensure the owner is satisfied.

Here is an article that answers your questions about payment: https://support.rover.com/hc/en-us/ar... Once you and your sitter confirm the reservation, you will pay at that time.
