Peppol vs SdI
SdI is Italy's mandatory clearance platform through which nearly all Italian invoices must pass in FatturaPA format; Peppol handles Italian public procurement documents (NSO) and cross-border invoices. Providers bridge both so one integration covers everything.
| SdI | Peppol | |
|---|---|---|
| Scope | Italian B2G, B2B and B2C invoices | procurement documents (NSO), cross-border |
| Format | FatturaPA XML | Peppol BIS / UBL |
| Model | centralised clearance | decentralised 4-corner network |
| Since | 2014 (B2G), 2019 (B2B/B2C) | entrenched in health-sector procurement |
Foreign suppliers invoicing Italian customers are outside SdI clearance — the Italian customer reports the cross-border invoice themselves, and receiving a structured Peppol invoice makes that painless. Details and deadlines on the Italy country guide.
