1. Open the Export submenu of the Invoicing module and select the integration you want to use for the export.
2. Select the invoices that you want to export to the accounting in the list, click on the gray button at the top and choose the action "Export".
3. A pop-up will then open where you can start the export. You can close this pop-up when all invoices have been exported. Exported invoices will now disappear from the list of invoices to be exported, so that you will not export invoices twice. If you close the dialog window too early, the export will be stopped.
