Transmission Infrastructure
PEPPOL vs. Direct E-Invoice Delivery
PEPPOL is the European network for secure exchange of business documents. When is it worth using — and when does a direct email delivery of the XML file suffice?
| Criterion | PEPPOL Network | Direct Delivery (Email / Upload) |
|---|---|---|
| What is it? | International B2B/B2G network for standardised document transmission | Transmission via email attachment or upload to supplier portal |
| Technical standard | AS4 protocol via Access Points; documents usually UBL (BIS Billing 3.0) | No unified standard; depends on recipient system |
| Adoption in Germany | Growing — EU-wide mandatory for certain procurement; not yet universal in DE | Very widespread — standard for most SMEs |
| Prerequisites for participation | Registration with an accredited PEPPOL Access Point required | None — immediately usable |
| Cost | Approx. €20–100/month for Access Point; cheaper at high volume | Near zero (email) or low-cost (supplier portal) |
| Security & auditability | High — encrypted, signed, delivery confirmation | Low for email; better for HTTPS upload |
| Degree of automation | Very high — fully automated receipt and processing possible | Low — manual steps at recipient often required |
| Mandatory in Germany | Currently only for specific EU procurement; not generally for XRechnung | Not regulated — free choice of transmission path for XRechnung (except specific portals) |
| Scalability | Ideal for high invoice volume (100+ per month) | Sufficient up to approx. 50–100 invoices per month |
Verdict
For most small and medium-sized businesses in Germany, direct delivery of XRechnung via email or through government portals is entirely sufficient — and free. PEPPOL only becomes worthwhile at high volume, for cross-border EU business, or when clients explicitly require it. Those planning to scale across Europe should evaluate PEPPOL early, however.
