What is an “Associated Vendor for expense tracking in QuickBooks”?

The “Vendor for expense tracking” drop-down list allows you to select which Vendor the current user is associated with for expense tracking. If the user only has permission to view and edit his or her own expenses, then the user will only be able to enter and track expenses for the Vendor you set as the “Associated Vendor for expense tracking in QuickBooks”. If the user can view, edit, and approve expenses for multiple Vendors, you can select a Vendor as the default Vendor for this user in expense tracking, but the user will be able to view and add expenses for the other Vendors as well.
