Hi, I know this is a very old post but just in case anyone else wanted to include a £ on their invoices and estimates.
I managed to successfully add the pseudo class “before” to some of the table elements in the inspector, which adds the pound sign before the totals.
.footer-sub-total .invoice-footer-right-td:before, .footer-vat .invoice-footer-right-td:before, #invoiceBalanceAmount:before, #invoiceNetTotal:before, #invoiceAmountPaid:before, .tdItems3:before, .tdItems5:before, .tdItems6:before
{
content: "£";
padding-right: 1px;
}
This seems to work for me when creating the PDF invoices and estimates.
You may need to tweak the CSS slightly depending on the template you’ve chosen.
Cheers
