Set up a new installment payment plan for a customer. When created, the initial charge depends on the deposit amount and start date: if no deposit and no future start date, the first payment is charged immediately; if a future start date is set with no deposit, only card validation is performed; if a deposit is provided with no future start date, the deposit plus first payment are charged immediately; if a deposit is provided with a future start date, only the deposit is charged immediately.
