Yes, you can find an overview of your last invoices in your Shipcloud webUI under "Billing". There you can download them via the small gray PDF button.
If you need invoices that are older than 12 months, we can send them to you by e-mail on request. Please send us a message with the requested billing details from the e-mail address you registered with to our support team at support@shipcloud.io and we will send you the PDF files again.
