When PTSB used Worldpay's then-majority stakeholder FIS to get access to its payment systems, the two companies formed their first partnership in July 2021. Afterwards, FIS received $11.7 billion last year from US-based private equity firm GTCR for its share of the Worldpay company.

PTSB will have access to more Worldpay products thanks to the extended relationship, such as Worldpay Dynamic Currency Conversion (DCC), the company's e-commerce platform for international business transactions, and Worldpay ePOS, its point-of-sale and integrated payment solution.

PTSB's head of personal banking, Jeff Harbourne, discussed the agreement and said that it will allow the bank to offer new options to both current and potential clients that will help them "grow their businesses and accept payments across all channels."

PTSB now offers a number of business banking services, including as virtual terminals, online payment solutions, and point-of-sale terminals previously made available through the Worldpay alliance, in addition to deposit and current accounts, mortgages, term loans, and asset financing.

The bank has 1.3 million clients overall in Ireland.
