At the end of each month, Adyen calculates the final invoice amount. Sometimes, it may happen that we either charged you too much, or too little. For example, this scenario can occur if you apply tiered pricing. To balance it, we book an
InvoiceDeduction line item in the settlement report, when necessary.
In this example, Invoice 201111000553 refers to the invoice number mentioned in the invoice of the given month. The amount may appear with debit or credit columns.
