Okay so I found a website that gives the basic requirements for a Tax invoice but I need so advise from you.We ship products from multiple address from multiple vendors to one customer,now as state on the site you have to show the "to" and "from" address.Now the to address is the customers address but what about the from address,I mean we might have a couple per order depending on the products purchased.So what address should I show on the invoice? our business address or each individual address the products is shipped from? I would say our business address but is it legal to do so?
