Vify Order Printer PDF Invoice

We have been using this app since January. The invoices are attractive, easy to read and the large colour images make it easy for customers to check there order.
Today I found that I could add a button to the confirmation email that allows customers to download a PDF invoice. We had been getting so many complaints from customers wanting a PDF invoice and now they can download it themselves from the Shopify confirmation email. Very simple, easy instructions to install. All the code is written for you.
Grace in customer support is very helpful.
