CHARLESTON, SC — Grant Street Group announced today that Charleston County in South Carolina has officially gone live with PaymentExpress® as its new payment processing software.

A handful of county departments and divisions made the transition, most notably the Department of Revenue Collections and the County Treasurer’s Office.

“We are thrilled to partner with Grant Street Group to deliver added convenience and ease of payment to Charleston County taxpayers,” said Charleston County Treasurer Mary Tinkler. “The implementation process and training for this new initiative was seamless, and has already been well received by both the team in the Treasurer’s Office and our customers.”

Charleston is the first county in South Carolina to implement PaymentExpress. It is the third most populous county in the state, home to nearly half a million people.

“We’re pleased to have Charleston County as a customer and proud of the smooth rollout we accomplished together,” said Phil Runyard, Grant Street’s Chief Strategist for Payments. “The fact that the Department of Revenue Collections and the County Treasurer’s Office both chose PaymentExpress, after thoroughly evaluating all options in a competitive bidding process, speaks volumes about the emphasis we place on providing a payment platform tailored specifically to the unique needs of government entities.”

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