# I’m unable to push the invoice to the IRP as it throws an error for the Project name/Project Reference Number. What should I do?

The project name must be a string within 20 characters. To verify the project name:

*   Go to the _Time Tracking_ module on the left sidebar.
*   Choose **Projects**.
*   Locate the project that you have associated with the invoice and click **Edit**.
*   Verify the project name. If it exceeds 20 characters, update the name to be within 20 characters.
*   Click **Save**.

Then, you’ll have to edit and save the invoice. To do so:

*   Go to _Sales_ on the left sidebar and choose **Invoices**.
*   Navigate to that invoice and click **Edit**.
*   Update the **Project Name** to match the project name you verified earlier, ensuring it is within 20 characters.
*   Click **Save**.

Now, you can push the invoice again to IRP without facing any errors.
