@financica/peppol

Peppol network toolkit for TypeScript. Provider-free participant discovery and reference data: check whether a company is reachable on the Peppol network, read the document types it accepts, enrich it from the public Peppol Directory, and resolve the right electronic address scheme (EAS) per country.

No API keys, no access point, no per-call cost — it talks to the public Peppol SML, SMP, and Directory directly.

npm install @financica/peppol

Participant reachability (SML → SMP)

Resolve a participant's SML NAPTR record to its SMP, then read the SMP's ServiceGroup to confirm registration and list the document types it can receive. Node only (uses node:crypto for the SML hash and node:dns for the NAPTR lookup).

import { lookupPeppolParticipant } from "@financica/peppol";

const result = await lookupPeppolParticipant({ scheme: "9925", value: "BE0123456789" });
// → { status: "registered", participantId: "9925:BE0123456789", documentTypes: ["invoice", "credit-note"] }
//   { status: "not_registered", participantId }
//   { status: "error", participantId, message }

// Pass `environment: "test"` to query the test SMK instead of production.

This targets the OpenPeppol-operated SML (…sml.prod.tech.peppol.org), which replaced the retired EC edelivery.tech.ec.europa.eu zone — and the modern NAPTR discovery that superseded the old CNAME scheme. A DNS name that doesn't exist (or carries no NAPTR) means the participant is not registered; any other DNS/transport failure returns status: "error" so callers can distinguish "absent" from "couldn't check".

Directory enrichment

The public Peppol Directory carries business-card data for participants who opted in. Best-effort only (not a source of truth for reachability):

import { buildCanonicalParticipantId, lookupPeppolDirectory } from "@financica/peppol";

const entry = await lookupPeppolDirectory(
	buildCanonicalParticipantId("9925", "BE0123456789"),
);
// → { name: "ACME NV", countryCode: "BE" } | null

EAS schemes by country

import {
	getPeppolCountryScheme,
	PEPPOL_COUNTRY_SCHEMES,
} from "@financica/peppol/schemes";

getPeppolCountryScheme("DE"); // → { country: "DE", scheme: "9930", example: "DE123456789" }

@financica/peppol/schemes, @financica/peppol/document-types, and @financica/peppol/countries are free of Node built-ins, so they are safe to import in a browser bundle (e.g. to build a country dropdown or label document types). The main entry pulls in the Node-only lookups.

Country e-invoicing profiles

Provider-neutral, hand-verified per-country facts for building an e-invoicing integration: the legal delivery network, the company and (separate, when one exists) VAT participant EAS schemes, where the VAT/registration number is validated (VIES vs BRREG), statutory archival years, and the org-number length to gate onboarding inputs on.

import { getCountryEInvoicingProfile } from "@financica/peppol/countries";

getCountryEInvoicingProfile("NO");
// → { network: "peppol", companyIdentifierScheme: "0192", vatIdentifierScheme: null, … }

A test pins these profiles to the addressing table in ./schemes so the two views cannot drift.

Document type classification

import { classifyPeppolDocumentType } from "@financica/peppol/document-types";

classifyPeppolDocumentType(rawBusdoxId); // → "invoice" | "credit-note" | "order" | … | "other"

document-types also exports the canonical BIS Billing 3.0, Self-Billing 3.0, and Invoice Response document type and process identifiers for registration payloads.
