Customize Admin Invoice Display

[enrich]

Hi Support,

 

I want to add extra field say “Special Discount” in admin Invoice Display area and printing Invoice.

i.e. Billing > Invoice > ( Paid / Unpaid) > click Invoice id for details

 

Url like (admin/invoices.php?action=edit&id=15)

 

Please see attachment for more idea.

 

Thanks in advance

I don't believe there is anyway to add a field in that spot. What I would recommend doing instead is just adding a new line to the invoice called special discount and for the amount put a negative number which will subtract that amount from the total.
