Switzerland — QR-bill, SIX and e-invoicing watch

Switzerland has no national B2B e-invoicing mandate in 2026. The QR-bill however is mandatory since 30 September 2022 for all payment slips, and the Confederation requires structured e-invoicing from suppliers of the federal administration since 2016.

Regulatory timeline

• 2 September 2003 — SCSE 1st generation. Federal law on certification services in the electronic signature domain, legal basis for Swiss qualified signature.
• 1 January 2016 — Federal B2G e-invoicing. The Federal Administration mandates electronic invoicing for its suppliers above the CHF 5,000 threshold (FOBL general terms applicable to federal contracts).
• 1 January 2017 — Revised SCSE. New electronic signature act aligned on eIDAS, mutual recognition of Swiss/EU qualified signatures by sectoral bilateral agreement (ongoing negotiation).
• 30 June 2020 — QR-bill launch. Swiss Payment Standards v2020 introduces the QR-bill as the replacement for orange (BVR) and red (BV) payment slips. Coexistence phase opens.
• 30 September 2022 — End of BVR/BV. SIX Interbank Clearing ends acceptance of BVR (red) and BV (orange) slips in the clearing system. QR-bill becomes the only structured payment means.
• 21 November 2024 — Swiss Payment Standards v2024. ISO 20022 update aligned on CBPR+ migration and SEPA RTP; Swico publishes v2.6 of the e-invoice model.
• 2025 — ESTV B2B e-invoicing consultation. The ESTV opens a public consultation on the opportunity of a B2B e-invoicing mandate aligned with ViDA, with no firm schedule to date.
• 2026 — Watch. No Swiss B2B mandate announced. Switzerland remains outside ViDA but follows European generalisation through OpenPeppol for cross-border invoicing.

Deep dives — 10 dedicated pages

Ten dedicated pages drill into every dimension of the Swiss e-invoicing ecosystem — the reforms and framework (QR-bill 2020, ISO 20022 early leadership, no mandate but high voluntary adoption, low VAT regimes, federal B2G since 2016, the non-EU / ViDA position), the technical specs (UID/IDE identifiers), and the real-world B2B usage that long predates any regulation (Migros/Coop retail EDIFACT, Nestlé/Novartis/Roche industrial & pharma EDI, the SWIFT/SIX banking backbone).

Reforms & framework

• QR-bill — the QR-Rechnung since 30 June 2020 · Switzerland flagship innovation: a Swiss QR Code embedding all payment data, live since 30 June 2020. It replaced the orange (ISR/BVR) and red (IS/BV) payment slips, finally withdrawn on 30 September 2022. SIX governance, Swiss Payment Standards format.
• ISO 20022 — Switzerland early leadership · Switzerland harmonised its payment traffic onto ISO 20022 from 2018 (pain.001, camt.05x), well ahead of the global SWIFT MX migration. SIC/euroSIC operated by SIX, Swiss Payment Standards recommendations. The QR-bill is the consumer-facing capstone of that backbone.
• No mandate — voluntary adoption via providers · Switzerland imposes no B2B e-invoicing mandate. Voluntary adoption is nonetheless high, driven by providers (PostFinance, Abacus, SIX Paynet, Pingen) and the swissDIGIN forum guidelines. A pull/opt-in model, no tax clearance.
• VAT (MWST/TVA) — 8.1% / 3.8% / 2.6% · Standard rate 8.1% (raised from 7.7% on 1 January 2024 to fund the AHV/AVS old-age scheme), special accommodation 3.8%, reduced 2.6% (food, books, medicines). Among the lowest VAT rates in the world. Legal basis MWSTG / VAT Act, run by the FTA/ESTV.
• Outside EU / ViDA — bilateral agreements and cross-border · Switzerland is outside the EU: ViDA does not apply directly. Cross-border invoicing with the EU runs via bilateral agreements and export rules (zero-rating), complying with the EU customer format (PEPPOL, Factur-X, FatturaPA). Watching the ViDA 2030-2035 roadmap.

Technical specs

• UID / IDE — CHE-XXX.XXX.XXX · Business identification number UID/IDE (CHE-XXX.XXX.XXX), operated by the FSO since 2011. The VAT number = UID + MWST/TVA/IVA suffix. Linked to the commercial register (HR/RC). PEPPOL ICD 0183 (CH UID).
• Federal B2G — mandatory e-invoicing since 2016 · Since 1 January 2016, every supplier to the Confederation on a contract above CHF 5,000 must invoice electronically, via the federal platform (E-Rechnung, historically run with PostFinance/Conextrade then SIX). Eight years ahead of EU Directive 2014/55.

Real-world B2B usage

• Retail EDIFACT — Migros, Coop, Denner, Aldi, Lidl, Manor · Migros + Coop duopoly, plus Denner, Aldi Suisse, Lidl Schweiz, Volg and Manor. GS1 Switzerland-led EANCOM subset (ORDERS, DESADV, INVOIC), GLN/GTIN, VANs and AS2. The real retail B2B rail, predating and parallel to any regulation.
• Industrial & pharma EDI — Nestlé, Novartis, Roche, ABB, Lonza, Sika · Heavy verticals: food (Nestlé), pharma (Novartis, Roche, Lonza), power & automation (ABB), specialty chemicals (Sika). Swissmedic pharma serialisation, GS1 Healthcare (GTIN + GLN + SSCC), EDIFACT D.96A/D.01B over OFTP2 and AS2.
• Financial centre — SWIFT, SIX, ISO 20022 sese/semt · The back office of the Swiss financial hub: SWIFT (HQ in La Hulpe, CH operations), securities settlement at SIX SIS, ISO 20022 sese (settlement) and semt (reporting) messages. SIC/euroSIC for cash. The data backbone of the banking sector.

Technical schema

Three technical layers coexist in Switzerland: QR-bill (payment), ISO 20022 flows (bank initiation and reporting), and the B2G or voluntary B2B e-invoice format (Swico, ZUGFeRD, PEPPOL).

• Swiss QR Code: 2D QR code embedding bank details (IBAN/QR-IBAN), amount, currency (CHF or EUR), reference (27-digit QRR with modulo 10 checksum or ISO 11649 Creditor Reference), creditor and debtor name and address, additional information.
• ISO 20022 pain.001: payment instruction issued by the debtor to their bank; Swiss Payment Standards v2024 restricts ISO options for Swiss usage.
• camt.053 / camt.054: bank statements and operation notices for automatic reconciliation (Strd CdtrRefInf = QR-bill reference).
• IDE/UID: format CHE-XXX.XXX.XXX, assigned by the Federal Statistical Office, suffixes HR (Commercial Register), MWST/TVA/IVA (VAT-liable), NOGA.
• Currencies: CHF (Swiss franc) dominant; EUR allowed for international and border QR-bills.

Submission flow

The QR-bill follows a payment flow, not a fiscal clearance. The biller generates a PDF with Swiss QR Code at the bottom. The debtor scans the code in their e-banking (Twint, UBS, PostFinance, Raiffeisen, etc.), generates a pain.001, and the bank executes the payment via SIC4 (Swiss Interbank Clearing) or euroSIC. The camt.054 reporting enables automatic reconciliation on the creditor side.

For federal B2G, the supplier submits the invoice via the e-rechnung.bit.admin.ch portal in ZUGFeRD 2.x, Factur-X, PEPPOL BIS, yellowbill or Swico. The BIT then routes to the accounting centre of the destination administrative unit (federal SAP S/4HANA).

Validation

• SIX Group — QR-bill Validation Portal: validation.iso-payments.ch — official validator for QR-bills and ISO 20022 Swiss Payment Standards messages.
• ESTV — Federal Tax Administration: estv.admin.ch — VAT, online returns via ePortal.
• BIT — Federal Office of Information Technology: bit.admin.ch — e-rechnung portal for Federal Administration suppliers.
• Swiss Payment Standards: SIX Swiss Payment Standards 2024 — ISO 20022 implementation and QR-bill rules.
• Swico: swico.ch/e-rechnung — sectoral e-invoice model (ICT) and best practices.

Common pitfalls

1. QR-IBAN vs IBAN by reference type. If the reference is a QRR (27 digits), a QR-IBAN must be used (positions 5-9 between 30000 and 31999). If it's an ISO 11649 Creditor Reference (RF…), a standard IBAN suffices. Confusing them rejects the QR-bill on collection.
2. Recursive modulo 10 QRR checksum. The 27-digit QR-Reference checksum uses the recursive modulo 10 algorithm (SIX table). A checksum error is not caught by all e-bankings and may produce payments blocked at the creditor bank. Test systematically before emission.
3. DE/FR/IT/EN language parity. The QR-bill must be printable in the four national languages depending on the debtor's canton. Anticipate translation of labels "Konto/Compte/Conto/Account", "Referenz/Référence/Riferimento/Reference", "Zahlbar durch/Payable par/Pagabile da/Payable by", etc. Latin extended character sets must be supported (ä, ö, ü, é, è, ç).
4. No B2B mandate = vigilance on archiving. Without fiscal clearance, the company is solely responsible for probative-value archiving (LTVA art. 70, OTVA art. 122 — 10-year retention for commercial documents, 20 years for real estate). Use an eCH-0044 compliant electronic vault or a certified archiving third party.
5. SCSE ≠ eIDAS, partial bilateral recognition. Swiss qualified SCSE signature is not automatically recognised in the EU (and vice versa), except for certain domains covered by Switzerland-EU bilateral agreements. For a cross-border B2B invoice, plan for dual signature or partner validation.
