Invoice bill

If you bought your iPhone at Apple Online Shop, see the section "View or Print Invoice" in this support article:--> Viewing & Changing Orders - Shopping Help - Apple , or contact Apple directly using this link:--> Contact Apple for support and service

In all other circumstances (Apple phisycal Stores, Authorized Resellers, who have their own accounting system) contact the seller and ask for a copy of that document.
