In our line of business we add a % contingency based on the overall itemised bill.
This is a separate line that the customer can see as % amount before VAT is added. Much like the VAT is set currently - how the customer can see at the bottom of the invoice - the amount that 20% VAT is.
I would like an additional % custom field at the bottom of the page showing to allow for a % Contingency of the overal bill. This would be added BEFORE Vat.
So a invoice would be
Net Total =
Contingency % Total =
Vat 20% total=
Gross Total =
