I know a way to help you get past the error and add your client smoothly, AnnieMB.
The issue you're experiencing happens when you import data from QuickBooks Desktop (QBDT) or activate payroll after adding employees to QuickBooks Online (QBO). It can also occur if the name of the customer, supplier, or employee you want to add is already listed in your company.
In QuickBooks Online (QBO), each client must have a unique name even if other details differ. When you have two clients with the same name, you can differentiate them by slightly modifying the name in QuickBooks like adding a middle initial or a [1] at the end. In addition, perform the following troubleshooting to get past the error:
- Find the duplicate vendor, employee, or customer
- Update the employee, vendor, or customer info
- Add the employee, vendor, or customer again
