2. Invoice Validation
   • Validates XML invoices using the ESS validator API for compliance.
   • Generates detailed error reports for failed validations.
3. Invoice Sending
   • Allows sending validated invoices via email.

4. Invoice Management
   • Enables authenticated users to edit, delete, and manage their invoices.
5. User-Centric Design
   • Material-UI-based interface for a consistent and familiar user experience.
   • Responsive design supporting desktop and mobile use.

The application is dockerised for easy deployment:

1. Clone the repository.
2. Create a .env file in backend/ with required variables
3. Run docker-compose up.
4. Access the app at localhost:3000.
