Discount on bills during payment process

Discount on bills during payment process

Hi,

we do apply discount rates (that we agreed with our partners beforehand) whenever we pay in a certain delay. Example: 10.000 euros bill (vat included). And when we execute the payment order throught our bank system, if this is done in less then 10 days after the date of the bill, we are allowed to apply for that vendor a 2% discount rate on the amount of the bill (or partial payment-yes this happens also :) ).

How can we manage this ? Because giving this input at the bill level will automatically apply it during the whole time of the lifcycle of the bill which is not really what we want because often we dont want to pay that fast and then the discount rate at the bill level is wrong because we have paid too much too.

How can we manage this ?
In french we say: escompte de paiement sous x jours.
Or german: skonto wenn in X Tagen bezahlt wurde.
