Re: Missing heading for Tax
In
Admin->Locations/Taxes->Tax Rates
you click and Edit Tax Rate. There is a description field that you must have left blank. It's not needed but it will display in the area you are asking for. Make sure it's something that makes sense for your tax rate so your customers understand it. For instance, I am in USA, Arizona. I put "Tax (includes county & city taxes)".
I can't help with your other item, sorry.
Re: Missing heading for Tax
Yes that works Thanks so much. With the description added to different tax rates they show up seperately in the Invoice too
