7.1 The Principle of Flexible Integration

Every enterprise is unique. Multi-channel integration ensures all client environments can comply without costly ERP changes.

Every enterprise is unique. Some operate modern APIs, others rely on batch files or legacy systems, and many have subsidiaries with little to no IT capability. Softrust and Bluelight provide a multi-channel integration approach that ensures all client environments can comply without costly ERP changes.

Capture Technology

All integration channels converge into SmartAPI → FIRS MBS for unified compliance processing

7.2 Integration Option 1: SmartAPI (Direct API)

Real-time API integration for high-volume enterprises with modern ERP systems

Best For

  • High-volume enterprises (1000+ invoices/month)
  • SAP, Oracle, Dynamics ERP platforms
  • Real-time invoice clearance requirements
  • Organizations with dedicated IT teams

How It Works

The client's ERP system calls SmartAPI endpoints directly via HTTPS. Invoice payloads are submitted in JSON format using our canonical schema. SmartAPI handles transformation, validation, digital signing, and FIRS submission - returning clearance status in real-time.

< 2s Clearance Response Time
99.9% API Uptime SLA

Key Integration Steps

  1. Endpoint Setup: Configure ERP to call SmartAPI
  2. Authentication: Install client certificates
  3. Data Mapping: Map ERP fields to canonical schema
  1. Testing: Validate with test invoices
  2. Go-Live: Enable production processing
  3. Monitoring: Dashboard and alerting setup

7.3 Integration Option 2: File-Based Integration

SFTP/batch processing for legacy systems and scheduled invoice processing

Best For

  • Legacy ERP systems without API capability
  • Batch processing environments
  • Organizations preferring file-based workflows
  • Scheduled invoice submission (daily/weekly)

Supported Formats

CSV Files
Excel (XLSX)
XML/UBL
JSON

7.4 Integration Option 3: Email Connector

Simple email-based submission for subsidiaries and ad-hoc invoice processing

Perfect For

  • Small subsidiaries with minimal IT resources
  • Ad-hoc or low-volume invoice submission
  • Quick setup without technical integration
  • Remote offices and branches

How It Works

Users email invoice files (PDF, Excel, CSV) to a dedicated secure email address. SmartAPI processes attachments automatically, performs FIRS clearance, and replies with receipts. Rejected invoices include detailed error messages for correction.
