# Month Closing Invoice (MCI)

The Month Closing Invoice (MCI) is issued automatically on the 1st of each month. It provides a full reconciliation of all per-message usage costs charged at Meta rates for the previous billing period across every WhatsApp Business Account (WABA) connected to the 360Dialog Hub.

The MCI reflects the final usage costs after applying all credit balance prepayments made during the billing period.

If a remaining balance is due, the payable amount is automatically charged to the payment method saved in the Hub. 

If the automatic payment attempt fails, a manual payment will be needed. 

For more details, see [Funds](/docs/hub/funds.md)

If no billable messages were sent during the month, no Month Closing Invoice is issued.
