Define Payment Terms

Hi all,

Though i am not a FICO consultant but i have to define the payment terms.

the scenario is

1. 90% payment against Pro. Inv. bal with 30 days Credit

2. 10% Advance, 90% Payment within 30 days of invoice

3. 100% Pmt Through LC with 180 Days Free Credit from dispatch

I understand that this can be done through OBB8 but i need to know what all conditions should be made in order to carry out this.

Pls guide.
