How to capture a settlement discount which is after vat and cant be captured in the discount field as this is before vat ?

Hi @warren6,

Let's set up your Discount value field on your invoice placed after VAT so you'll get the correct total amount.

Here's how:

1. Go to the + New menu.
2. Select Invoice.
3. Fill up the form as necessary. 
4. Enter the discount amount on the Discount value field. 
5. Press the Switch (down and up arrow) button, so your VAT gets deducted from the subtotal before the discount. 
6. Hit Save and close.
