After a long search and some fails over the years and changes to shopify key functionality I was dispairing as a UK based store that needs to account for VAT unless a B2B in europe. We are OSS registered in ireland. We have just installed the trial and completed full tests with all parameters, including using a VPN to spoof locations, and it just works. Looking forward to seeing the app in practice.

Great support, i recommend

It is a great and simple app. The customer support is very helpful and has quick response times. I can recommend this app to anyone looking for a VAT validation system on their webshop for B2B customers

Veel vergelijkbare apps zijn namaak of werken niet naar behoren, maar deze app doet precies wat hij belooft. Dit is duidelijk de originele en betrouwbare oplossing binnen dit segment. De installatie is eenvoudig en alles werkt direct zoals verwacht.

Voor de nieuwe PEPPOL wetgeving in België hebben we Billit via de Webwinkelfacturen koppeling geïntegreerd in onze Shopify store. Echter vragen deze zelf geen btw nummer op, daar is OO-EU Tax Exemption app de redder geweest. . We verkopen zowel B2C als B2B, in binnen en buitenland. Registratie van het correcte btw nummer en toepassing van de 'BTW verlegt' regel vóór de checkout indien nodig is van groot belang. . Hebben veel apps getest, maar deze stak er ver bovenuit. Veel mogelijkheden qua instellingen en styling. . Voor onze koppeling moest de btw nummer in de order notes komen zonder prefix, na een snel antwoord van de support was dit in no-time toegevoegd als optie voor iedereen. . Fantastisch gevoel om een app support te hebben die zo snel en oplossingsgericht handelt!

Goede app met zeer goede support !

Great service. We had a request and they added it the same week!

This app does exactly what it promises. EU VAT numbers are validated automatically and business customers can check out VAT-free without any issues. Setup was quick and straightforward, and everything worked right away. Support is responsive and helpful. Since installing this app, our EU B2B checkout process has been much smoother. Highly recommended.

Needed some settings support and was fixed with 1 day. Perfect!

Fast and efficient support when required.

Works fine, setup is easy - and if something doesn't work the support team is great. replies quickly, and it's helpful.

We needed some help after installation. Support responded very quickly and immediately fixed a minor issue. The app is working as intended. The FAQs make it easy to configure the necessary Shopify settings yourself. If you need further assistance, you can rely on the friendly support team. Thank you!

Very, very good support and certainly a very useful tool for us that do b2b within EU.

The app works very well and the support team replied so fast and quick to a problem that we stumbled upon (how the appblock looked in our shop), they were ready to help us and fixed it for us!

Erg prettige app om zakelijke transacties buiten Nederland snel te regelen. Geen gedoe meer met BTW/terugstortingen. Installeren gaat makkelijk en werkt doeltreffend.

This app is very useful and greatly helps with the retention and validation of personal and corporate NIFs, reducing the risk of fraudulent purchases.

Very fast support and help from the team. Fast implementation and the app does what it should!

Yes, the app does exactly what you expect. The app fills the gap that Shopify has when it comes to reverse charging VAT in the EU. Support is also good.

If you sell digital products to European businesses, this app removes one of the most tedious compliance headaches you'll face: VAT ID validation and B2B tax exemption. The setup was straightforward, but what truly sets this app apart is the exceptional customer support. When I ran into configuration questions specific to my use case, selling online courses, the support team was responsive, knowledgeable, and patient. They didn't just answer my questions—they made sure everything was working correctly. Without their help, I would have struggled to get the setup right. The app does exactly what it promises: validates VAT IDs through the official VIES platform and automatically applies the correct tax exemption at checkout. My B2B customers from other EU countries now have a seamless purchasing experience, and I no longer worry about manual validation or compliance errors. For any merchant selling to European businesses, this is a must-have.

I used ChatGPT to find a reliable VAT verification app, and after testing several options for standard Shopify plans (non-Plus), this one turned out to be the best by far. I wanted a more seamless integration into our sales funnel and reached out to support. To my surprise, they replied almost immediately — and even offered to handle the implementation free of charge. The app runs smoothly, VAT checks are lightning-fast, and the support team is exceptional. I can confidently recommend this app without hesitation.
