Your subscription term and billing period start the day you receive your car. When you make your reservation, you pay for the first 30 days in your car. At the end of those 30 days, you will get the next invoice, which covers the following 30 days as well as any credits or debits that have been added to your account (such as a referral credit or a bridge toll). Payment for that invoice is processed 10 days later. When you return your car, we issue a closeout invoice 10 days later based on your final balance, after we've applied any vehicle/mileage fee credits for unused time.
