If you export your invoices to Excel or CSV, they are not marked as exported automatically, so if needed, you have to mark them as exported manually one by one. Here is a workaround for that, but you should be careful because you cannot filter invoices by date, customer, etc., all approved invoices created from work orders of a specific type will be marked as exported.
Note Please make sure that you are logged in as a user with the ‘Administrator’ role and the ‘Export Invoices to CSV’ setting is turned on for your work order types.
Let’s say you have multiple approved invoices created from work orders of a specific type and you need to mark them all as exported.
On the Miscellaneous tab, click Export Invoices to CSV.
On the Export Invoices to CSV page, select the appropriate work order type, and then click Export Invoices.
As a result, all invoices created from work orders of this type will automatically change the status from ‘Approved’ to ‘Exported’.
