Order Printer Pro: PDF Invoice

I just started using order printer pro today but already love it. It has been such a hassle to manually make each invoice for B2B customers as Shopify does not include an invoice feature in their system. 10 dollars a month is a very fair price for what they offer; it takes away hours of work for me per month and it's convenient for my customers.
Thank you Blanca for the excellent, kind help with my questions, all is set up now for future success!
