PwP with respect Unit Price, Discount, Charges and VAT

Standard Behavior of Pay-when-Paid WRT to Unit Price, Discount, Charges and VAT

When the PO line has Discount and VAT AND the Project invoice has NO VAT
Supplier Invoice Section
Invoice Amount = Unit Price + /- Discount + VAT +/- Charges

Supplier Invoice Lines Section
Unit Price – Price for the Item / Service
Amount = Unit Price +/- Discount

Customer Invoice
Invoice amount = Invoice Amount = Unit Price + /- Discount + VAT

**There is no way on a project invoice that I can give ‘Charges’ on to it, if the project invoice only comprises of PO**

When the PO line has Discount and VAT AND the Project invoice has VAT

See the second example below where the ‘Totals’ screen for the Supplier invoice shows all the elements.i.e. Line amount, Discount, Charges, VAT etc.

**Discount is not shown currently in the Totals form as I am accessing it after the invoice is posted. ** Please consider the discount to be 15%
