Case Study Example Video
Pierce Processing is a credit/debit card processor. It provides outsourced services to credit/debit card issuers. The issuer pays a percentage of transaction fees to Pierce for providing the following services: Credit authorization, Fraud detection, Accounting and reporting.
Issuers outsource this function to companies like Pierce because of the high cost of maintaining their own IT systems to perform this function.
Pierce currently serves the 10 of the top 20 issuers of the country. The 20 top issuers comprise 90% of the credit card market. The 10 of the top 20 that are not Pierce’s customers either use Pierce’s competition or perform the function in-house. The number of credit card transactions is growing at 3% annually.
Pierce earns a percentage of the transaction fee of each transaction.
