Creating an invoice for daily receipts from the previous quarter!?

Yes, it is possible, but you will have to remove it from your daily receipts. Are you subject to VAT? If you are exempted from VAT, you can simply adjust this in the daily receipts themselves.

If you are subject to VAT and this is in a closed period, I would do it via the reports -> income and expenses -> manual input. Just enter the amount as negative. You then note that the customer wanted an invoice and then you create an invoice in the usual way.
