Croissant, a shopping and rewards app for luxury fashion, reports that its Croissant Pay solution is now available in Shopify Checkout and at the register through Shopify POSand all other PoS systems. Fashion brand SIMKHAI is among the first to offer it through the new integration. “Reaching a luxury customer costs more every year, and the first order rarely pays for itself. The industry needs two things: alternative means of acquiring the right shoppers, and deeper loyalty,” says John Howard, CEO and Co-Founder at Croissant. Croissant Pay brings that spending power to a brand's checkout and its stores, and the brand pays only when a member spends.
