Orange County, CA Goes Live with PaymentExpress®

May 13, 2019


ORANGE COUNTY, CA — Grant Street Group announced today that, following a four-month implementation, the Orange County Treasurer-Tax Collector’s Office has officially gone live with PaymentExpress® as its new electronic payments platform.

The third largest county in California, and the fifth largest in the nation, the County of Orange encompasses the cities of Anaheim and Santa Ana and is home to over 3.1 million citizens.

Between the Treasurer-Tax Collector’s Office and the Probations Departments, PaymentExpress will process over $2 billion annually in e-payments for the County of Orange.

“We are excited to partner with Grant Street Group to lower property tax processing costs of e-checks and credit cards for both taxpayers and the County on these property tax payments of over $2 billion annually,” said Orange County Treasurer Shari Freidenrich. “Our implementation went very smoothly, and I am proud of the County staff that assisted with the implementation, and the professionalism and hard work of the Grant Street Group staff on the project.”

Using PaymentExpress, the Orange County Treasurer-Tax Collector’s Office and Probations Departments will be capable of accepting all major debit and credit cards (Visa, MasterCard, Discover, American Express) for payments online, over the phone, via mobile or tablet devices, and in the office. E-check payments will also be available online.

“Going live with PaymentExpress in Orange County is a major milestone for Grant Street Group in California,” said John McCarthy, Executive Director of Sales. “We excel at completing implementations for multiple county departments on a tight time frame, and we appreciate the Orange County staff members’ financial and technical expertise that contributed to a successful implementation.”

PaymentExpress, Grant Street’s secure e-payments service, is used to process over $5 billion in credit card and e-check transactions annually.
