1.  Make an attempt to collect the difference on-counter, as it is the most straightforward way.  When a person returns a car - you act as usual and document the damages. Then, you may ask the hirer to pay for the damage. 


2. If step 1 is not possible - you charge from the deposit on Cardoo's card and send us your usual proofs of the damage and issue the invoice in our name. We'll take care of soft collection ourselves. Then, you will have to unblock the rest of the deposit.
