Hi @basvweb,
Yes, it is. Although, you’ll need to install two different plugins to do so.
To see the complete list of your generated invoices, date of creation, and order linked, you can use our Number Tools extension. After, installing and activating, go to WooCommerce > PDF Invoices > Number Tools > Choose a number store, select Invoice > Click on View, and now you’ll see the complete list of generated invoice numbers.
If you want to export the orders that have an invoice number, you could use the Advanced Order Export For WooCommerce plugin. It allows you to filter orders by custom fields and also add those custom fields to your export file.
For your case, you’ll need to add this condition, under Filter by order > Custom fields: _wcpdf_invoice_numer
<> empty
…and add the _wcpdf_invoice_numer
metakey as a new field, from the Set up fields to export section, right column. After adding the custom field to this area, it will be flashing. Drag in drop this field to the left column and choose your desire position in the exported file.
Let me know if you manage to view and export your invoice numbers ??
