Our customers request different line items be shown on their invoices so we have a few different templates that we use.  We will start with the standard invoice template, modify the format and then save it as a new template.  

We added the "Balance Due" option through the Designer Layout feature and the total is correct, however, the format does not include the comma for the thousand notation.  So instead of see $1,000.00 we see $1000.00.  How can we fix this?
