## Principal Invoices

| Symptom | Likely cause | Fix |
|---|---|---|
| You cannot access the invoice workspace. | The sign-in screen is displayed or the credentials have not been entered. | Complete **Enter User Name** and **Enter Password**, then select **Login**. If needed, use **Reset Password**. |
