Great and incredibly quick support by Katy! Many thanks for your competent and super friendly help!

Fantastic app! Once you get the hang of it, it's very easy to use and set up, just make sure you have everything, i.e. tax settings etc, set up in Shopify first (tutorials can be found at Articles link in the footer). Support is extremely friendly, helpful and patient, I got a little grumpy in one question and they handled it very professionally and gracefully, for which I thank them.

Great support from Katy to help us make our invoice the best it can be!

Works great and awesome support!

Great app, and fantastic support, Sufio have done so many customisations just for us, cannot recommend them highly enough!

I would recommend usage of Sufio to anyone who wants to save their time and effort when setting up and managing invoice agenda. Support of multiple languages is a big plus.

The support from the developers is very fast and to the point.

I have just started using Shopify...and had a lot of little things that needed to be
done to comply with Italian requirements.....Sufio responded immediately to any
questions I had and found solutions for me ....I would highly recommend Sufio.
It is straightforward and logical to use with a brilliant back up support service.

We've been using Sufio for around 2 years ago, great product and excellent support! - TritonDatacomOnline.com

Top class customer service - they changed a few elements on my invoices for my custom requirements. I can absolutely recommend their program to all Shopify store owners!

Great App! Customer service is wonderful - quickly made changes for me :) Highly recommend them!
