Exclude invoice lines from early payment discount

Hi All,

I have a business scenario where I need to put a goods (product) item and a service item on the same invoice. VAT is applicable to both items.

The customer is entitled to early payment discount (e.g. 2% off if paid within 2 weeks) which is controlled by the payment term.

However the discount can be applied only to the product.

Any suggestions how I can implement this?

I have tried to use the Discount Basis option on the Payment Terms, setting it to Lines and Tax, not Freight Items and Tax. -- and change the type of item in the Inventory Item to "Freight Item".
