The Internet is an important resource for both business-to-business and business-to-consumer commerce. Its advantages over private networks are often overshadowed by concerns about using pubic networks for commercial transactions. We present a case study that describes adoption of an Internet-based auto finance system by a financial insitution and multiple auto dealerships. We discuss four issues that we needed to solve in order for the system to be accepted. These are: 1) the implications of the open nature of the Internet on existing business-to-consumer relationships, 2) security of enterprise data and systems, 3) ensuring connectivity across enterprises, and 4) the management of information assets generated by large volumes of electronic transactions.
