Fixed day limit to calculate Due date for payments

Question

Dear Gurus,
My Management wants to regulate its cash flows and want to use terms of payment in such a way that customer invoicing should be due on whole month evenly
Proposed payment plan is that
if invoices are created with 01 to 15th of the month, term of payment should be 40 days due net
if invoices are created with 16 to 25th of the month, term of payment should be 30 days due net
if invoices are created with 26 to 30th of the month, term of payment should be 25 days due net
so according to above scenario, plan should be
Invoice date     Payment terms     payment due date
9/1/2011     40     10/11/2011
9/15/2011     40     10/25/2011
9/16/2011     30     10/16/2011
9/25/2011     30     10/25/2011
9/26/2011     25     10/21/2011
9/30/2011     25     10/25/2011
Requirement,
Please advice how to cater it through OBB8 or should we have to look towards ABAP solution

Hi
Create the payment terms like
1)
Payment Terms           Z01
Day Limet                    15
In Payment Terms TAB
Term      Percentage            No,of.days
1             0.00                          40
2)
Payment Terms           Z01
Day Limet                    25
In Payment Terms TAB
Term      Percentage            No,of.days
1             0.00                          30
3)
Payment Terms           Z01
Day Limet                    30
In Payment Terms TAB
Term      Percentage            No,of.days
1             0.00                          25
This will resolve your issue,we can create multiple levels with same payment term with different day limit
