Prepayments
The Prepayments tab displays and manages prepayment invoices related to the current freight invoice.
This tab becomes available when the Prepayment parameter is enabled in the Details tab.

Prepayment Invoice Logic
Prepayment handling follows the same rules across the Accounting, Cargo, and Port Agent modules.
Each invoice includes a Prepayment checkbox. When enabled, the invoice is treated as a prepayment invoice.
Prepayment invoices may be added to a final invoice. The prepayment and final invoice must have the same invoice type and direction.
