Core Concepts
This is the architecture layer: how commercial billing data is validated by tax authorities in real time, and how documents are signed and routed. If you are looking for the plain-English meaning of consolidated e-invoice, pool or validation, start at Concepts instead — this page assumes them.
The E-Invoice Validation & Clearance Lifecycle
Tax compliance submission follows a structured 5-step lifecycle. Each step represents an automated cryptographic transformation and validation milestone.
| Step | Milestone | Business Purpose | Applet Used |
|---|---|---|---|
| 1 | Commercial Invoice Generation | Sales order billing or POS checkout creates commercial invoice in ERP | Sales Invoice Applet |
| 2 | Data Transformation & Sign | Data formatted into LHDN’s schema and digitally signed by BigLedger as your intermediary — no certificate of yours is involved | MY E-Invoice Admin Applet |
| 3 | Tax Authority API Submission | Real-time REST API transmission to tax gateway (e.g., LHDN) | MY E-Invoice Admin Applet |
| 4 | QR Code & UUID Clearance | Tax authority validates schema, issues unique UUID and clearance QR stamp | Government Tax API |
| 5 | Recipient Dispatch | Validated e-invoice, with its QR code, e-mailed to the buyer and viewable by them | MY E-Invoice Portal Applet |
PEPPOL Global Network Routing
While government tax APIs handle local country tax compliance, the PEPPOL (Pan-European Public Procurement On-Line) network provides standard international B2B electronic document delivery:
- PEPPOL Participant ID: Unique global business identifier (e.g., scheme ID + registration number) used for routing.
- Access Point (AP): BigLedger acts as a certified PEPPOL Access Point, automatically converting commercial invoices into UBL XML standards for instant cross-border delivery.
