Credit note
A credit note is a document issued when it is necessary to adjust an original commercial invoice. This may occur for several reasons, such as product returns, discounts that were not initially applied, or errors in the original invoice.
This type of document has important operational and financial implications:
Accounting impact
A credit note affects accounts payable by reducing the total amount owed to the supplier, since it adjusts the original invoiced value.Customs and import impact (before nationalization)
If the products have not yet been nationalized, a credit note may impact the preparation of the Import Declaration (DIM).
For example, when a supplier issues a credit note for products that are still in a Free Trade Zone, it is still possible to adjust customs duties, taxes, and other charges, as these calculations are based on the declared value.Costing and liquidation impact
Credit notes also affect the final cost calculation, since product costing is based on both the quantities and the total value of the complete logistics operation. Any adjustment to the invoice value directly impacts the final cost per product.
