 # QuickBooks Desktop FAQ
@@ -92,3 +92,56 @@ Note: Disconnecting clears all imported options from Expensify.
 ## Can I Export Negative Expenses to QuickBooks Desktop?
 
 Yes. QuickBooks Desktop accepts negative expenses across all export types.
+
+---
+
+## Why Am I Seeing the QBWC1039 Error?
+
+If you see:
+
+> QBWC1039: Unique OwnerID/FileID pair value required
+
+This means the Expensify application is already registered in QuickBooks Web Connector and a second registration is being attempted. QuickBooks requires each application to have a unique OwnerID/FileID pair. If one already exists, the new registration is rejected.
+
+## How to fix the QBWC1039 error
+
+## How to remove the existing Owner ID using the CP3 tool
+
+You'll need the [CP3 tool from Intuit](https://http-download.intuit.com/http.intuit/CP3Tool/QBWC_CP3Tool.exe) to remove the existing Owner ID stamp.
+
+1. Open **QuickBooks Desktop**.
+2. Download and open the CP3 tool.
+3. Select **Select the file**, then search for your QWC configuration file.
+4. Select **Open**, then click **Remove Stamp**.
+5. On the **QuickBooks Application Certificate** window, select **Yes**, then **Continue**.
+6. On the **Access Confirmation** window, select **Done**.
+7. Follow the remaining instructions, then select **OK**.
+8. You should see a confirmation that the Owner ID was removed. Select **OK**.
+9. Exit and reopen both **QuickBooks Desktop** and **Web Connector**.
+
+## How to re-add the Expensify application in Web Connector
+
+1. In Expensify, go to **Settings**.
+2. Select **Workspaces**.
+3. Select your Workspace.
+4. Click **Accounting**.
+5. Click **Sync now** to re-initiate the connection.
+
+QuickBooks Desktop will prompt you to approve the Application Certificate.
+
+1. Select **Yes, always; allow access even if QuickBooks is not running**.
+2. Choose the **Admin** user from the dropdown.
+3. Click **Continue**.
+4. **Important:** Proceed to the password screen and save the password when prompted. This step must not be skipped.
+5. Click **Done** in the confirmation window.
+
+Return to Expensify and allow the Workspace to finish syncing.
+
+## How to fix the QBWC1039 error when QuickBooks Desktop is hosted (e.g., Rightworks)
+
+If your QuickBooks Desktop is hosted in a remote/cloud environment (such as Rightworks or another hosting provider), you will likely **not** be able to run the CP3 tool yourself. In this case:
+
+1. Contact your hosting provider's support team and request that they remove the existing Owner ID stamp using the CP3 tool. For example, Rightworks support is available at **(888) 417-4448, option 2** (available 24/7). They can perform a screenshare via phone and set up a three-way call if needed.
+2. Your hosting provider may need to close your remote desktop session to make the changes.
+3. **Important:** After the hosting provider completes their changes, you must use the **same QWC configuration file** you originally saved. Do not generate a new one.
+4. Reconnect the Expensify application following the steps in **How to re-add the Expensify application in Web Connector** above.
