Project Overview

Project Name

"NRA Submission Hub" - Software for automating the process of submitting transport declarations for high fiscal risk goods to the National Revenue Agency of Bulgaria.

Technical Scope

The system integrates with NRA's API endpoints to process and submit various declaration types for goods transportation, ensuring compliance with Bulgarian fiscal regulations for high-risk cargo movements.

NRA Transport Reports

1. Import - starting from another EU member state territory and ending in Bulgaria
2. Export - starting from Bulgaria and ending in another EU member state territory
3. Cancellation of unique transport number (UTN) for non-executed transport
4. Confirmation of receipt/dispatch of high fiscal risk goods
5. Internal transport - starting and ending within Bulgaria territory
