In the Account Charges window (Charges button in Meta Ads or Monitor Balance), choose the account and period and click Export PDF. The file follows the format of Meta's invoice summary: account, period, and each charge with its date, transaction ID and the amount charged to the card (including tax, as in Meta Billing), plus the total charged and the tax included. It's ready to send to your client. The PDF uses exactly the period shown on screen.

The card shown is the account's current primary card, because Meta doesn't report which card paid each charge.
