Samina Hussain-Letch, executive director of Square U.K., said the launch of the firm's corporate card product in the U.K. would give merchants speedier access to funds and help them more easily manage their daily expenses.
"When designing this product we went back to our mission of making commerce easy," Hussain-Letch told CNBC. Based on internal research Square found that small and micro businesses "prefer their funds to be consolidated in one place," she said, adding that real-time access to funds was also an important factor.
