Hi - I am looking to change the sales invoice sent to customers to make it tax department compliant. (Need to add words "Tax Invoice" and also include our tax number. 

Can't find where or how to do this? 

Any help....anyone???

Hello @dricast 

How you are creating the invoices?

[dricast]

Hi - it is going to the customer as the packing slip (which if fine as they have paid by then). 

All want to do is add words "Tax Invoice" and our tax number "XXX-XXX-XXX" 

Changing packing slip wording appears bit complicated. Only want to add the info on the packing slip not elsewhere (i.e. so the info doesn't appear elsewhere on the site)

Actually that’s is incorrect. Is only the packing slip. Invoice is not produced. How do I send an invoice??
