E-Invoicing Guide: Digital Invoices & Compliance 2026
E-invoicing is the structured electronic exchange of invoices between systems — not just emailing a PDF.
E-Invoice vs PDF Invoice
| PDF Invoice | E-Invoice |
|---|---|
| Human-readable document | Machine-readable structured data |
| Emailed manually | Transmitted via network (PEPPOL, etc.) |
| Manual data entry by recipient | Auto-imported into accounting systems |
Global E-Invoicing Mandates
- India: e-Invoice via IRP portal for businesses above turnover threshold

PEPPOL Network
PEPPOL is the standard e-invoicing network in Europe. Businesses register with an Access Point to send/receive structured invoices.
