    Root Causes

    Plastiq allowed businesses and consumers to pay bills with credit cards even when recipients didn't accept cards, charging a 2.85% fee. But margins were razor-thin after card processing costs, and the company took on credit risk by advancing payments. Rising interest rates in 2022-2023 increased the cost of float capital. Plastiq filed for Chapter 11 in May 2023 after burning through $140M.
