[Back](./) # 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. * * *
