What happens when lists are imported into QuickBooks Online if there are customers with identical names?

When importing lists into QuickBooks Online, if there are customers with identical names, the system displays an error message. This mechanism is in place to prevent confusion and maintain data integrity, as having multiple customers with the same name can lead to issues with reporting, billing, and customer management. QuickBooks Online requires the user to address these duplicates before the import can proceed, ensuring that no conflicting or ambiguous customer entries are created in the system. Therefore, this process helps safeguard the accuracy of your customer database by flagging duplicates that need to be resolved rather than allowing a potentially problematic situation to develop.
