There’s one last unsolved problem in the payment ecosystem, and it’s a trillion-dollar one: recurring payments for subscription fail 24% of the time. Why? Because of a systemic problem in a payment ecosystem that was built for one-off transactions, not subscriptions. FlexPay is a FinTech startup that helps merchants retain more subscribers by recovering failed credit card payments on recurring transactions, unlocking revenue that was about to be lost. Organizations with recurring payments encounter systemic issues in the payment ecosystem that reject on average one-quarter of all recurring payments, and two-thirds of these rejected payments are false declines -payments that should have been approved. By upgrading the payment rails with artificial intelligence, the FlexPay platform creates unique recovery strategies for each transaction, achieving unparalleled approval rates. INVISIBLE RECOVERY™ interacts directly with the payments system to avoid customer visibility to the failed payment. It is the fastest and most effective tool to recover soft declines.
