A computer system, a service, a computer program product, and an associated method combine the ease of credit card purchases over the Internet with the flexibility of traditional leasing. The financing on demand system is a financing e-utility that prepackages customer entitlement processes, such as credit approvals, lease structures and rates, terms, and conditions with secure electronic delivery and legally enforceable document archiving, such as e-signatures. The system provides the advantage to the merchant of reducing internal administration costs, speeding up current business processes, and enhancing the ease of conducting business with end users and vendors alike. It produces secure legal enforceable documents that meet financing company requirements. Merchants provide the software for the financing on demand system to customers by software token, CD ROM, or smart card media. The system has no fixed credit limits or payment structures, is completely encrypted and secure, and uses non-proprietary open standards architecture in inputs/outputs to permit convenient integration to any vendor's Web site.
