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!

I asked for a basic feature — setting default payment terms per client. They admitted it's possible but said I’d need to upgrade to their premium plan, which is 3x more expensive. So they can do it, but they just want to charge way more for something simple. Feels like they’re forcing you to pay extra for functionality they already have, not recommended.
