Hey @Stephane_Paillard, good news, this is now live!
Head to your Dashboard → Billing and you’ll find a Download button on the Invoices card. You can grab all your invoices in one go or pick a specific month, and it comes down as a ZIP of the PDFs with a CSV summary included.
@Chris_Bellairs this should cover your date-range ask too. Give it a try and let us know how it works for you!
