Milestone Billing

Hello,

We are a Engineering company

Our Pricing procedure is

Basic

+ Excise Duty

+ Edu. Cess

+ H.Edu. Cess

Sub Total

+ CST / VAT

Sub Total

+ Transportation

Grand Total

Now we want to implement Milestone billing as our billing pattern is such.

10% Advance on Basic Price

10% Against drawing approval from Customer on Basic Price

70% + All Taxes against Material Despatch from Factory

10% After one year of product supply.

Now tell me how can i Configure this scenario in SAP.

As at present I have configured milestones billing but it is calculating advance on Basic + Taxes instead of Basic only.

Please guide

Best Regards,

Vishal Kadia
