Discover the benefits

  • Identify atypical activity for the current day using baselines established for your financial institution’s historical activity or by comparing your ACH transactions to industry rules
  • Receive timely notifications when anomalies are detected, allowing you to address concerns
  • Adhere to Nacha rules around notifications of change and help avoid future rule violations, contributing to overall efficiencies within the ACH network
  • Avoid overdraft situations by monitoring same-day activity at the final same-day deadline

Use cases

  • Notifications of change (NOC)
    • Improve your operations by monitoring when your institution receives the same NOC more than once, outside of prescribed Nacha-designated change timeframes, indicating that an originator has failed to make updates.
  • Same-day debit large dollar variance
    • Gain insight on your Fed account when unusual high-dollar debit batches will settle on the current processing day in the final same-day window and potentially require settlement account funding.
  • Micro-entry forward and Micro-entry return monitoring
    • Monitor velocity of forward/return micro-entries for originators that use small-dollar entries for account verification purposes and potentially mitigate your institution’s fraud risk.
