WesPay History

Our Journey

The history of our association includes some very important milestones, including the formation of the Automated Clearing House (ACH) payments network. WesPay is very proud of our distinction as the first non-profit association dedicated to the advancement of electronic payments. The following are a few notable events in the 40+ years since our founding in 1972:


A special committee on Paperless Entries (SCOPE) was formed to consider the possibilities of using computer entries to replace paper checks and deposit slips between members.


The Special Committee on Paperless Entries was converted into the California Automated Clearing House Association (CACHA), providing the first operational ACH in the United States.


The San Francisco and Los Angeles Clearing Houses merged to form the California Bankers Clearing House Association.


CACHA’s expanding membership led to renaming the association Western Payments Alliance, or WesPay.


Western Payments Alliance and The California Bankers Clearing House merge, bringing together their check and ACH expertise.


WesPay divests check clearing services to The Clearing House.


The association expands its service territory on 01/01/2011 with the merger of the Northwest Clearing House Association (NWCHA). The new organization retains the name WesPay and was expanded by 180 members in Washington and Alaska and three professional staff.


The association expands its service territory on 01/01/2014 with the acquisition of assets and staff of Viewpointe’s Association Services. The combined service area of the new organization is home to 25 percent of the nation’s population.


WesPay is a membership-based payments association focused on regulatory compliance, risk management and operational sound practices across various payments channels. We work with over 1,200 member organizations including financial institutions, third-party payment providers and other organizations supplying payments-related services.
