Manually send an invoice to a client and receive a copy

We often manually send an invoice to a client. Currently I do not see a way to send myself, or a member of my fulfillment staff a copy of the invoice. I see there is a report “receivables” which can be run and sent to my fulfillment team nightly. This report shows outstanding invoices. Hooray! However, if a client pays their invoice before the report is run & sent, the invoice is not included in the report. I am also aware of the report “net income by invoice” but this report does not show an orders details/products, only amount due.

Are there any work arounds? Specifically, I am looking for a copy of an invoice to be sent to me/my team or a report that shows invoices sent with product specific details.
