Swedish E-Invoicing (E-fakturering) Skill
This skill is the authoritative reference for everything related to Swedish electronic invoicing: the legal regime, the Peppol network and BIS Billing 3.0 wire format, Sweden-specific CIUS validation rules, integration with Swedish accounting systems and bank rails, the consumer e-faktura ecosystem, the upcoming ViDA mandate and the pending Swedish domestic mandate inquiry (Dir. 2026:9), and concrete implementation strategy for software builders.
The data in Claude's training is stale and unreliable for this domain. Peppol specifications update twice yearly (May / November releases). The Peppol PKI migrated G2→G3 in late 2025. ViDA was adopted 11 March 2025 and entered into force 14 April 2025. Swedish Dir. 2026:9 was issued 5 February 2026. Skatteverket gained expanded online-audit rights from 1 April 2026. Always consult this skill rather than answering from priors.

Core facts that govern every answer
These are short enough to inline; the references expand each.
Legal status (April 2026): B2G mandatory since 1 April 2019 (Lag 2018:1277). B2B voluntary. B2C uses bank rails / Kivra, not Peppol. ViDA cross-border B2B mandate hard date: 1 July 2030. Domestic mandate inquiry: Dir. 2026:9 issued 5 Feb 2026, final report 30 Nov 2027. Realistic Swedish domestic mandate window: 2029–2031 on a Belgium-style decentralised Peppol model.
Wire format: Peppol BIS Billing 3.0, UBL 2.1 syntax, EN 16931 semantic. CustomizationID = urn:cen.eu:en16931:2017#compliant#urn:fdc:peppol.eu:2017:poacc:billing:3.0. ProfileID = urn:fdc:peppol.eu:2017:poacc:billing:01:1.0. Current release: Billing 3.0.20 (November 2025). BIS 4.0 / PINT convergence in late 2025 / early 2026.
Network: Peppol four-corner (C1 sender → C2 sending AP → C3 receiving AP → C4 receiver). AS4 v2.0 over HTTPS. SMP discovery via NAPTR/SHA-256 (migrated from CNAME/MD5 in 2025). PKI: G3 only after end-2025. SMP servers must run on port 443 from 1 February 2026.
Authority: DIGG is Sweden's Peppol Authority, regulator under Lag 2018:1277. DIGG's Peppol-ID: 0007:2021006883. Skatteverket: 0007:2021005448. Per regeringsbeslut Fi2025/01826, Peppol functions transfer to Upphandlingsmyndigheten on 1 July 2026; DIGG merges into PTS by 1 January 2027. SFTI ESAP 6 (EDIFACT) was removed 1 July 2025; Svefaktura is deprecated.
Identifier formats: Swedish orgnr → schemeID="0007", 10 digits no dash. Swedish VAT ID → SE + 10 digits + 01 (e.g. SE556732100001), prefix mandatory (BR-CO-9). For sole proprietors DIGG recommends GLN (0088) over personnummer (0007) for GDPR.
Swedish payment encoding (SE-R-011): PaymentMeansCode 30 for Bankgiro AND Plusgiro; the discriminator is cac:FinancialInstitutionBranch/cbc:ID = SE:BANKGIRO or SE:PLUSGIRO. Legacy codes 56 / 50 are forbidden. Bankgiro 7–8 digits (SE-R-008/009), Plusgiro 2–8 chars (SE-R-010). OCR reference goes in cbc:PaymentID (BT-83), Luhn-validated.
F-skatt (SE-R-005, FATAL): Swedish suppliers issuing invoices with VAT category S MUST include the literal string "Godkänd för F-skatt" in the document, typically cac:PartyLegalEntity/cbc:CompanyLegalForm or as cbc:Note. Missing this string is the most common reason public sector authorities reject invoices.
Archive (BFL): Retention 7 years after the calendar year of the financial year (SFS 2024:342). The inbound UBL XML is itself the verifikation. Storage in another EU country permitted under 7 kap. 3a § with Skatteverket notification. From 1 July 2024 paper kvitton may be destroyed once correctly scanned.
Posture and style
When answering questions in this domain:
- Cite the specific law section, regulation, MDFFS, or Peppol BIS rule by identifier. "BR-CO-15", "SE-R-011", "BFL 7 kap. 1 §", "Lag 2018:1277 §4". Vague answers signal stale knowledge.
- For UBL fragments, output real, valid XML with full namespaces and example values, not pseudocode.
- For build-vs-buy or vendor selection, give numbers, €/SEK, monthly minimums, per-document costs, certification fee tiers, break-even volume, not adjectives.
- When a regulatory date is involved, distinguish (a) hard EU deadline, (b) currently-known Swedish proposal, (c) speculation. The user is technically sophisticated and is making product decisions; mistaking speculation for binding fact is the worst possible failure mode.
- Be willing to say "the spec is currently in flux", Peppol BIS 4.0 / PINT convergence, the DIGG → Upphandlingsmyndigheten / PTS reorganisation, the Dir. 2026:9 outcome, and the post-ViDA national mandate landscape are all moving targets in 2026–2027.
