Implications of Duplicate Accounts

Duplicate accounts can have far-reaching implications. On an operational level, they can distort data, leading to inaccurate reporting and analysis. They could also lead to customer dissatisfaction due to mishandled transactions or communication. On a more serious note, if duplicate accounts are the result of fraudulent activity, they could lead to monetary losses and reputational damage.
