Credit card payment services provider iPayment Holdings Inc. will lay off 30 employees from its Westlake Village headquarters in September, according to the company and the state Employment Development Department. The company filed a Worker Adjustment and Retraining Notice with the state on July 18, just a month after Paysafe Group, in London, finalized its acquisition of iPayment. Kate Aldridge, vice president of corporate communications for Paysafe, said in an email to the Business Journal that the company does not take lightly the decision to cut staff. “We are now working hard to support those affected by providing wide-ranging assistance, both in terms of the severance packages we are offering as well as the job-seeking support we are organizing,” Aldridge said in the email. IPayment provides payment and processing solutions for small and medium-sized businesses. Last year, the company generated processing volumes of more than $25 billion from more than 137,000 merchant customers across the United States.
