Great app, and even greater support. I would like to see duties/tariffs being displayed as line items in invoices/receipts.

A very helpful App for our business. The Control over the invoicing and design is very flexible and provides alternatives and meets our region very well.

I am not only extremely satisfied with the app itself but also with the outstanding support team behind it — especially our account manager, Lewis!! These are people who genuinely treat your problems as their own and go above and beyond to resolve issues and provide assistance. Their dedication and service truly deserve respect and recognition. It is a great feeling to work with a team we can genuinely count on.

Sufio has completely streamlined our invoicing process in Shopify. The app is beautifully designed, easy to use, and packed with smart features that save us hours every week. From automated invoice creation to flawless customization, everything works exactly as promised. The highlight, however, is the outstanding support team — lightning-fast replies, deep product knowledge, and genuine commitment to solving any issue. They make you feel like a valued partner, not just a customer. Absolutely 5 stars!

Suffio Support are a great help, they are quick to respond and I have found Veronika really helpful and easy to communicate with.

Absolutely fantastic app with more functionality than first meets the eye. To top this off the customer support is absolutely amazing! Incredibly helpful and friendly staff.

Es lohnt sich, Sufio zu nutzen. Die Designs lassen sich super einfach anpassen, man benötigt keine Vorerfahrung. App sehr benutzerfreundlich. Der Support hilft schnell und präzise. Und dahinter sitzt nicht nur ein KI Chatbot, sondern es hilft auch realer Mitarbeiter, wenn man es wünscht.

Hervorragender Support – ich bin wirklich beeindruckt! Ich schreibe nur selten Bewertungen, aber diese Erfahrung hat definitiv eine verdient. Lewis hat mir nicht nur geduldig (und mit Humor!) bei einem Problem geholfen, das letztlich auf ein kleines Versehen meinerseits zurückging – er hat sich außerdem die Zeit genommen, ein separates Problem mit Sonderzeichen zu untersuchen und tatsächlich eine Lösung dafür umgesetzt! So einen schnellen, menschlichen und wirklich hilfreichen Support findet man heute nur noch selten. Vielen Dank – ihr habt einen Fan gewonnen. Und zur App selbst: Sufio ist die fünfte Rechnungs-App, die ich getestet habe – und mit Abstand die intuitivste, benutzerfreundlichste und zugleich leistungsstärkste. Alles wirkt durchdacht, sicher und angenehm aufgeräumt. Der Einrichtungsprozess ist klar strukturiert, dabei aber flexibel und anpassbar. Es funktioniert einfach – automatisch dort, wo es soll, und anpassbar dort, wo es zählt. Man hat sofort das Gefühl, in guten Händen zu sein. Ich bin ehrlich froh, dass ich mich nicht für die erstbeste App entschieden habe – sonst hätte ich Sufio nie entdeckt.

It works great when our B2B customers require a PDF invoice. Easy, user friendly, and support is quick to respond.

Sufio is a truly great invoicing solution : powerful, reliable, and easy to use. The app integrates seamlessly with Shopify and covers everything we need for professional, compliant invoicing. But what really sets Sufio apart is the quality of their support. The team is incredibly responsive, helpful, and genuinely committed to finding solutions. They went above and beyond to help us during the setup phase, and their guidance made all the difference. Highly recommended!

I love this app! It is so easy to use and has provided everything we needed for our wholesale store. They have really great customer service too. Highly recommend!

There is a time difference for US merchant but the service people know what they doing and come up with great solutions.

I genuinely believe no webshop in the Netherlands (and likely many other countries) can go without Sufio. After testing numerous invoicing apps, this is possibly the only one that truly handles invoicing and credit notes properly. Sufio is absolutely essential if you serve business customers who require professional invoices for their administration. While it took me a little time to get used to the interface, I now find it intuitive and efficient. Beyond the powerful functionality, the support is outstanding. Incredibly friendly, fast, and knowledgeable. Sufio solved my invoicing headaches . Highly recommended!

Lewis was amazing for the set up of our Sufio invoicing, we needed invoices based on customer rules, and he made the whole process straightforward

Sufio is an excellent invoicing system! After trying and comparing several different invoicing app, we decided to go with Sufio—and we’re very glad we did. The system is user-friendly, but what truly sets Sufio apart is their customer support. The team is incredibly patient, detail-oriented, and always quick to respond. They’ve helped us with various customizations and often offer thoughtful, effective suggestions. Their efficiency and professionalism are top. Highly recommended!

Great customer support with quick responses and automatic fixes according to the requests of our company. Would absolutely recommend to use this tool!

It took us some time to set up everything just the exact way we need it (we are a B2B Catering company with german tax laws), but with the help of Sufio, we were able to accomplish everything. We are a customer since 1,5 years by now and are very satisfied with the ongoing good quality of the support. Thank you Olivia! :)

Easy to get started with the day to day configurations on your own. The onboarding with the Sufio flows fast and is super versatile in helping with shop specific requirements; let it be coding additional snippets, configuring designs, or aligning with data flows/fields outside of the Sufio app during the build-phase. Looking forward to soon scaling with Sufio. Can only recommend.

Excellent customer service. Veronika was quick in answering my emails concerning some setup issues I was having. She even suggested some improvements I could make. Wish all apps had such great customer service!

I should say that you’re a great partner for businesses like us. I’m extremely impressed how you handle our requests and flex the features based on our needs. Special thanks to Veronika and to the IT team! The only regret for me is that I haven’t switch to Sufio earlier. Keep going so we'll be your lifetime customer!
