EUVAT.app simplifies VAT management for cross-border B2B transactions within the European Union by automating key processes. Tailored for stores where VAT is included in product prices, the app recalculates net prices for eligible EU businesses using the reverse-charge mechanism, ensuring compliance with country-specific VAT regulations. By validating VAT numbers through the official VIES system, EUVAT.app ensures accuracy and provides exemption status directly within customer profiles. The app dynamically removes VAT when applicable, adapting to the unique VAT rates of each buyer’s country. It supports both modern and legacy e-commerce platforms, including Themes v.2.0 and 1.0, and is easy to install. Additionally, EUVAT.app is accessible in all EU languages, making it user-friendly across the region. Merchants receive alerts and notifications about invalid or potentially risky VAT numbers, enhancing security and streamlining operations.
