I have some information about making an employee to a supplier. QuickBooks is unable to save duplicate information for customer, supplier, or employee. You'll need to delete your employee profile to create your employee as a supplier.
Go to Payroll. Select Employees.
Edit employee profile.
Scroll down towards the bottom then click Delete employee.
After deleting, go back to the supplier's page and add a new supplier using the employee's name. If you don't want to delete the employee's account, you'll have to add a number or a letter at the end of your employee's name to make it unique. This way, QuickBooks won't prompt your for duplicate info.
In case you need help with other supplier's tasks, click this link to go to our general topics with articles.
Keep me posted if you still have questions or concerns. I'm always here to help. Take care and have a wonderful day ahead.
