I went thru the available code and structure and needed some technical clarification. So I sent a request to the CEO (Bjorn Forsberg-Chief Eternal Optimist). In a word, perfect.
Easily customizable invoice templates (html / liquid coding), walk thru setup, downloadable pdf comes from your domain to customer, no 3rd party pdf downloads for customers, pdf created and coded securely in neat URL.
Definitely some time and thought went into this app. Very handy and great for customers to receive invoice straight after purchase. Very happy.
Can't wait for the 'carrier pigeon' upgrade pak. Apparently pigeons still waiting for passports.
This app shouldn't be free!

A great app with superb customer support!! Thank you for adjusting the standard template according to my needs!

Great tool. Another thing not to worry about

Great tool for our invoices!!!...easy and practical solution for our customers....recommended!

I was already posting out receipts by Order Printer. However this APP can eliminate need for printing. Perfect tool that makes shipping email to customer, look more informative and professional.

Forsberg+2 apps are amazingly good!
Order printer pdf emailer is no exception.
Excellent! Easy to install and works perfectly.
Purchased others and pleased with them all.
Don't hesitate getting their apps.

Great app and so easy to get it done!

Thank you great App and free !!!

Perfect. Simple, clear, easy. Like all the add-ons from this company.
