Adding a question mark changes the tone to a question; the original phrase is a command, so keep the period.

Cultural Tip
In Italian business culture, asking for confirmation of a signature is common before processing payments or legal actions. Keep the tone polite but firm; adding “per favore” softens the command. In Southern Italy, you might hear a more informal “Dimmi chi l’ha firmato?” while in formal settings the imperative “Confermi” (third‑person) is preferred.
