B2B Invoicing Compliance in Switzerland: 2025 Guide

B2B Invoicing Compliance in Switzerland: 2025 Guide

Swiss invoicing compliance sits at the intersection of federal tax law, SIX Payment Services standards, and an evolving e-invoicing landscape. For B2B logistics companies — billing other businesses rather than individual consumers — the compliance burden is real and the cost of getting it wrong ranges from delayed payments to VAT audit exposure.

This guide covers the current state of Swiss B2B invoicing requirements in 2025, with specific focus on what logistics companies need to know, and how BackOffice addresses these requirements systematically.

Swiss VAT Invoicing Requirements

Switzerland is not an EU member and follows its own VAT legislation under the Mehrwertsteuergesetz (MWSTG). Swiss VAT (MWST) currently operates at a standard rate of 8.1%, a reduced rate of 2.6% for essential goods, and a special rate of 3.8% for accommodation.

Mandatory Invoice Fields for VAT Compliance

Swiss VAT law requires the following on every B2B tax invoice:

• Supplier identification: business name, address, and Swiss VAT number (UID number prefixed with "CHE-", formatted as CHE-XXX.XXX.XXX MWST)
• Customer identification: name and address
• Invoice date and a unique invoice number
• Description of goods or services supplied
• VAT rate(s) applied and the VAT amount broken out separately
• Total amount in CHF (or EUR for cross-border transactions)
• Payment terms

For logistics companies, the "description of services" field deserves careful attention. A generic entry like "delivery services" may be insufficient for audit purposes. Best practice is to reference the specific delivery order numbers covered by the invoice.

QR-Bill: The 2022 Mandate That Persists

The QR-Bill mandate, effective October 2022 under SIX Payment Services standards, remains in full force in 2025. The key requirements:

• All paper payment slips must use the QR-Bill format
• The QR code must encode the full SIX data schema
• QR-IBAN (for structured references) or standard IBAN (for creditor references) must be used correctly
• Physical dimensions of the printed payment slip are mandated

For B2B logistics companies invoicing dozens of customers daily, manual QR-Bill creation is not practical. BackOffice generates SIX-compliant QR-Bills automatically as part of the post-delivery invoicing workflow.

E-Invoicing Trends in Switzerland

While e-invoicing mandates in Switzerland are not yet as strict as in some EU member states (which have implemented mandatory B2B e-invoicing frameworks), the direction is clear:

eBill and Swiss Digital Invoice Standard

eBill is the Swiss electronic invoicing platform operated by SIX. It allows businesses to send invoices directly into customers' e-banking interfaces. Adoption among larger Swiss companies has grown steadily since 2020.

For logistics companies with large corporate clients, eBill integration is increasingly expected. Clients who receive invoices directly in their banking portal have lower friction to pay, which reduces days-to-payment.

PDF Invoices with Embedded QR-Bill

In 2025, the de facto standard for Swiss SME digital invoicing remains a PDF document with a compliant QR-Bill payment section. This format satisfies both the SIX payment slip standard and the VAT documentation requirement.

BackOffice generates this exact format: a VAT-compliant invoice PDF with the QR-Bill payment section embedded, ready for email delivery or digital archive.

Cantonal Variations

Switzerland's 26 cantons do not impose additional invoicing requirements beyond federal MWSTG law. However, cantonal tax offices conduct their own VAT audits, and audit procedures vary. Cantons with large logistics hubs — Zurich, Geneva, Basel-Stadt — have active commercial audit programmes.

Best practice for logistics companies operating across cantons is to maintain a complete, searchable invoice archive with all mandatory fields present. System-generated invoices from platforms like BackOffice inherently satisfy this requirement by creating a complete electronic record for every transaction.

Cross-Border Invoicing: Export Services

Swiss logistics companies frequently handle cross-border shipments to EU countries. Export services are generally zero-rated for Swiss VAT (Nullsteuer) under MWSTG Article 19, but documentation requirements are strict:

• Export declaration reference (Ausfuhrzollanmeldung) must be retained
• The invoice must reference that the service is zero-rated due to export
• Proof of export must be archived for 10 years

For import services — brokering customs clearance for goods entering Switzerland — different rules apply depending on whether the logistics company acts as importer of record.

The Compliance Case for Integrated Invoicing Software

The complexity of Swiss B2B invoicing compliance — QR-Bill format, VAT field requirements, sequential invoice numbering, cross-border zero-rating — makes a strong case for integrated invoicing software rather than manual processes or generic tools.

BackOffice was designed for exactly this environment. It maintains sequential invoice numbering, applies correct VAT rates based on service type, generates SIX-compliant QR-Bills, and archives all documents in a searchable repository. For Swiss logistics companies, it provides compliance as a byproduct of normal operations — not as a separate administrative burden.
