Cooperative Services, Inc. (CSI) is a service organization that provides a number of support services to credit unions. CSI was founded in 1989 by the six largest credit unions in the state of Georgia and what was then known as Georgia Central Credit Union (now Catalyst Corporate Federal Credit Union). Forty-eight credit unions currently own stock in CSI. More than 120 credit unions utilize the services of CSI. The cooperative support of credit unions has created an organization that benefits credit unions in terms of lower processing costs and a high level of service. CSI consolidated its check and ACH processing operations with PCS's operation in Irmo, SC in 2011. This consolidation resulted in a new company, PCSi, which in 2015 consolidated with MY CU Services. All CSI check and ACH products and services are performed by MY CU Services.
