I'm already using a custom form for the customer to complete in order to get a quote, I don't think is the solution - what I'm doing is creating the "item" in the commerce/inventory area so that thay can make a payment. On the completed order email notification I want the email to include details of the order - not just simply the "title" of the item.
If this doesn't work that way then I'll have to find another option for invoicing, but I'm hoping this can work as I want to keep everything within the Square site. I mean, it's what I'm paying the high price to have a Square site, am I right??
