Signature Design Concept

The keen-automated landing page will feature an interactive VAT calculation journey. Users will see a dynamic map of Europe and the UK, where they can click on different countries to see VAT rates and rules. As users input transaction details, the map will animate to show the flow of goods across borders, with VAT calculations updating in real-time. This interactive experience will be built using motion/react for smooth animations and transitions.

Landing Hero Motion Brief

The hero section will depict a digital map of Europe and the UK. As users enter transaction data, animated lines will connect countries, representing the flow of goods. The VAT calculation will be visually represented by changing colors and numbers on the map, providing an immediate visual understanding of the VAT implications. The animation will loop every 10 seconds, with interactive elements allowing users to explore different scenarios.

Interaction Model & Motion Direction

• Interaction Model: Animated
• The landing page will feature moderate scroll-triggered reveals and hover transitions. The interactive map will provide a dynamic and engaging user experience, enhancing the storytelling aspect of the VAT calculation process.

Non-Functional Requirements

• The system must ensure data security and compliance with GDPR.
• The system should handle high volumes of transactions without performance degradation.
• The system must be reliable, with an uptime of 99.9%.
