Data Flow Overview

The data flow within BigLedger’s architecture follows these steps:

1. Document Submission:
   Document Submission: Documents are submitted via REST APIs or through the user interface

2. Data Processing and Validation:
   The backend services validate the submitted documents for compliance and data integrity, integrating AI-driven analytics where necessary.

3. E-Invoice Service:
   This service applies validation rules, ensuring compliance with PEPPOL standards and any local e-invoicing regulations.

4. Document Storage:
   Once validated, documents are stored in PostgreSQL and large files are managed through Amazon S3 for efficient retrieval and backup.

5. Document Management Service:
   This service handles the storage and retrieval of documents and metadata, with support for APIs to external systems for document exchange.

6. Response to External Systems:
   BigLedger sends status updates and responses regarding document processing back to external systems, whether ERP platforms or financial gateways.

7. PEPPOL Network:
   For cross-border compliance, validated e-invoices are sent to the PEPPOL network for secure international exchange.
