The system includes an invoice having a base invoice amount with an amount of penalty funds calculated from the base invoice amount when the invoice is not paid in a timely manner. An application is submitted to an investor via the network for enrolling the vendor in the service system. At least one installment is disbursed from the buyer and received by the investor over the network. At least one payment is disbursed from the investor and received by the vendor over the network wherein the payment is equal to the base invoice amount thereby allowing the vendor to receive 100% of said base invoice amount.
