You can resend your invoices to your accounting software in the following way:
Create an additional accountancy package integration. If you want to send the invoices to the same e-mail address, copy the e-mail address from the other integration. Check "I want to approve each invoice in Storecove".
Go to: Receive > Invoices. You now see a button for the new integration behind the invoices. By pressing the button you send the relevant invoice to your accounting package again.
When you are finished, you can remove the extra integration.
