Over the past 30 days, customers in the Bluefin North group have experienced intermittent delays in their payout emails.  The responsibility for sending these payout/settlement emails lies solely with Bluefin and First Data, and we are currently awaiting their resolution of the issue.

CUSI does not have control over the timing or delivery of these emails to the utilities.

Typically, utilities receive their payout/settlement emails early in the morning, allowing them to reconcile promptly upon starting their day. However, due to the ongoing issues with Bluefin, these emails are sometimes being sent out hours later than expected, and in some cases, even at the end of the workday.  This delay is causing significant inconvenience and disruptions in the reconciliation process for the utilities in Bluefin North.

Bluefin is working diligently to resolve this issue as quickly as possible. CUSI sincerely apologizes for any inconvenience this has caused our customers. We appreciate your patience and understanding during this time.

We will provide updates as they become available.
