Another great app by this team that fixes some of the problems with Shopify for B2B orders. You can now send tax invoices direct, saving the hassle of making an invoice in your own accountancy system when asked for a copy by a customer.

This for the most part is my favorite kind of app. Intuitive and well laid out visually from a function over form point of view.
But the description here doesn't mention the "free" plan has 7 cents per email charges and "comming" is spelled wrong numerous times in numerous places.
