Bunkering Details

The main feature of Bunkering invoices in the system is the ability to link Daily Reports to the invoice. This is used to verify the actual amount of fuel delivered during bunkering.

Within the Services tab of a bunkering invoice, there are two vertically arranged subtabs on the left:

  • Services — Fuel-related services associated with the invoice;

  • Daily Reports — List of linked daily reports.

Services Subtab

The Bunkered Fuel block appears at the top of the Services subtab. It displays the types and quantities of fuel supplied under the invoice. For each non-zero fuel entry, corresponding service entries are automatically generated and appear in the general Expenses list within the module.

The following fields are shown in a table-like format for each fuel type:

  • Confirmed Quantity, MT: Stated fuel amount in metric tons.

  • Price: Cost per metric ton.

  • Total: Total cost (calculated as Total=ConfirmedQuantity×PriceTotal = Confirmed Quantity × Price ).

  • Delivered Quantity, MT: Actual delivered amount, based on linked daily reports.

  • Difference, MT: Difference between confirmed and delivered quantity.

  • Fuel Debt: Fuel underdelivery or surplus (calculated as FuelDebt=Difference×PriceFuel Debt = Difference × Price ).

Additional Calculated Parameter

Supplier Fuel Debt — Aggregated fuel debt value for the supplier (‘Issued By’ party on the invoice). Can represent a surplus or deficit.

SupplierFuelDebt=∑i=1nFuelDebtSupplier Fuel Debt = \sum_{i=1}^n Fuel Debt

Where n — the number of bunkering invoices.

Daily Reports Subtab

The Daily Reports subtab provides a summarized list of daily reports linked to this invoice (linked via the ‘Invoice’ field in the Daily Report card).
