Cimode, you should use customerid instead of invoiceid for JOIN condition.
SELECT I.*
  FROM Invoices I

       INNER JOIN
       (SELECT customerid, MAX(date) most_recent_date
          FROM Invoices
         GROUP BY customerid
       ) AS C
         ON  I.customerid = C.customerid
         AND I.date = C.most_recent_date
