Hi Ray,
If you are using a 'Classic' theme invoice you have an additional text option. This gives you plenty of space to add additional details to your invoice rather than having to use the footer options.
As far as your fax number and web address, you can again add this in additional text or alternatively add this now to the footer?
If you do require some assistance with HTML editing there are some great examples of invoices on our website that you can reference.
The additional text option places text in the middle of the invoice. I have NEVER received an invoice with the fax number, web address, banking details in the body of the document! The additional text option has always been available, this is nothing new. NOTHING has changed, too many promises not enough action. What is happening about the promised invoice wizard, nothing probably. Let me guess - it is with the developers. Do they actually exist?
