Payment Terms - 5% + 6% 10 days / Net 60

Hi,

I want to get your views on what is the best option to setup a payment term such as:

5% fixed discount, additional 6% if paid within 10 days, otherwise net 60 days.

Do you take the fixed discount as a sales discount, make a special order type for that, use Pricing Manager or even build a custom on the whole payment term?

I am also interested in reporting for this as well, depending on the best setup. Will it show the whole discount or would we have 2 discount fields?

Thanks,
