Cheque discounting service is offered only by few banks. For instance, if you have a cheque of $3000 outstation and the cheque will take 7 seven days for clearance, then bank will offer you a service for early payment. The bank can make an early payment, but they will pay only for certain percentage of the actual amount, here they will pay you $2000 but they will charge interest on it and the remaining $1000 will be paid, once the outstation cheques get clear.
