Is there a monthly list of every invoice with the full amounts for my accountant?

Yes. Reports → Monthly statements has, beside each month's statement, an Invoice summary as PDF and XLSX: every order with its amount in full, how it was paid, payment changes, house accounts, the top customer and the customers who ordered again. The statement stays the month in totals; the invoice summary is the month invoice by invoice. The Reports & insights tab in the docs covers both documents.
