If you see the error “The name supplied already exists. Another customer, supplier, or employee is already using this name.", this is usually caused by the following:
- The customer, supplier, or employee name you're trying to add already exists in QuickBooks Online.
Step 1: Find the duplicate supplier, employee, or customer
Search for a duplicate name of the supplier, employee, or customer you’re trying to add in QuickBooks Online.
- Select + New, then select Cheque.
- In the Payee▼ dropdown, enter the name you’re trying to add.
- Duplicate names appear on the list, and you’ll know if they’re added as a supplier, employee, or customer.
Step 2: Update the employee, supplier, or customer info
After finding the duplicate name, you can change the name or make it inactive if the profile is no longer in use.
- Depending on what you need to edit, do one of the following:
- Employees: Go to Employees.
- Suppliers: Go to Expenses and select Suppliers.
- Customers: Go to Sales and select Customers.
- Find and select the duplicate name and do one of the following:
- Edit the employee, supplier, or customer name. For example, add a middle initial or a [1] at the end.
- If the profile you’re editing is no longer active or in use, make it inactive.
Step 3: Add the employee, supplier, or customer again
Now you can try to add your employee, supplier, or customer again.
