I don’t know if this is useful anywhere else but we have a client in Scotland that needs a feature added for what is called CIS tax. This is a tax discount applied after VAT. I can’t see it being used anywhere else biut someohow we need to code it and it might help out somehwhere.
So, I suggest this.
On the discount tab we add the boxes below. A tab to add a decription so on the invoice it can tell the customer what the discount is for and a check box to apply the discount after VAT or Tax. The default will be that it applies a discount before tax. And then I suppose we need to ba able to add multiple discounts…..
