Custom text on Sales Invoices

Could an additional text box be added to sales invoices for custom notes or special terms on specific invoices.

Why not enter this text into line item Description column?

I would agree with antgweb here. I tend to use the “description” box to describe what ever service I have provided to the customer. It would be great to be able to add a seperate little note for the customer.

I use the Description column, however there are different T&Cs for different Customers. So I have to go back into the invoicing template to change invoicing text, which then means that the text on other invoices without those T&Cs is also changed.
