When payments are duplicated, financial institutions are required to return the funds to affected customers or businesses. This could means the bank absorbs the cost of the mistake, resulting in an immediate financial and/or reputational hit.
While recovery mechanisms between banks exist and help mitigate losses, the process requires time, resources and coordination, which can add some operational workload.
The magnitude of the issue is substantial. Financial companies lose billions of dollars annually due to mistakes like duplicate payments. The Institute of Finance and Management (IOFM) estimates that duplicate payments account for approximately 1.5% of an organization's overall outgoing cash flow (Fiscaltec). A business with $1 million in expenses, for instance, would pay out $15,000 annually due to duplicate payments. The potential annual cost of these duplicate payments can potentially reach billions at large institutions.
