anglais vers français Autre Finance (général)

"The Parties agree to the right to set off sums validly invoiced owed to one another leading to a net balance payment. In such case, the net balance shall be paid prior to the Due Date. Offset statements are to be initiated by the net receiving Party, within the month of invoicing."

I know what the term means in the context, but I don't know what the corresponding expression is in French.
