Data Duplication #

When you import client data, the system automatically prevents duplicates. If an email address already exists on your WHMCS installation, the system will not import the new client.

Instead, the system will perform the following actions:

1. The system returns the existing client’s ID.
2. The system merges the client currency, status, client group, and any new client invoices, services, transactions, support tickets, or other items into the existing client record.
