Swiss E-Invoicing Requirements: eBill, Peppol & B2G Guide

Switzerland takes a fundamentally different approach to e-invoicing than its European neighbors. While France, Germany, Italy, and Greece are rolling out sweeping B2B e-invoicing mandates under EU directives, Switzerland charts its own regulatory course as a non-EU country with no obligation to follow the EU's VAT in the Digital Age (ViDA) framework domestically.

So what are the actual Swiss e-invoicing requirements? The short answer: e-invoicing is mandatory only for B2G (business-to-government) transactions. Since 2016, suppliers holding federal government contracts above CHF 5,000 must submit invoices electronically. Beyond that, B2B and B2C e-invoicing remains entirely voluntary, and the Swiss Federal Council has announced no timeline for changing this.

That voluntary status does not mean adoption is low. Switzerland has built one of Europe's most successful digital billing ecosystems through eBill, the national electronic billing infrastructure operated by SIX Group. Over 3.5 million users receive and pay bills directly through their e-banking platforms, making eBill a significant force in Swiss financial infrastructure even without a legal mandate driving adoption.

What makes Switzerland's e-invoicing landscape distinct is that it cannot be reduced to a single regulation or system. Five separate pillars define how electronic invoicing works in practice:

The B2G federal mandate governing invoices to government entities
The eBill system providing nationwide digital billing through banking channels
The format and standards landscape, including Peppol, ZUGFeRD, and Swiss QR-bill specifications
The QR-bill and eBill distinction, two systems frequently confused but serving different purposes
EU ViDA cross-border implications affecting Swiss companies that trade with EU counterparts

Each pillar carries its own technical requirements, participant ecosystems, and compliance considerations. This article covers each in detail.

B2G E-Invoicing: Federal Contract Requirements

Switzerland's only mandatory e-invoicing requirement applies to business-to-government (B2G) transactions. Since 2016, every supplier to the Swiss federal administration must submit structured electronic invoices for contracts exceeding CHF 5,000. Paper invoices and unstructured PDF attachments are not accepted for these transactions.

The BBL (Federal Office for Buildings and Logistics / Bundesamt für Bauten und Logistik) administers this mandate for federal procurement. If your company holds a contract with any entity within the Bundesverwaltung (federal administration), you are subject to these rules once the contract value crosses the CHF 5,000 threshold.

What "structured electronic invoice" means in practice: The federal administration requires machine-readable invoice data in a standardized format. Sending a PDF as an email attachment does not qualify, even if the PDF contains all the correct invoice fields. The invoice must arrive in one of the structured formats aligned with Swiss e-invoicing standards, which are covered in detail later in this article. Companies already meeting Swiss MWST invoice compliance requirements for VAT purposes will find that B2G e-invoicing adds a format and transmission layer on top of those existing obligations.

Scope and boundaries. The mandate covers the federal administration specifically. Cantonal and municipal governments are not uniformly bound by this requirement. Individual cantons and communes set their own procurement rules, and while some have adopted similar e-invoicing practices, there is no national mandate extending beyond the federal level. Suppliers working with multiple levels of Swiss government should verify requirements separately for each contracting authority.

No expansion on the horizon. Unlike the EU, where mandatory B2B e-invoicing is advancing rapidly across member states, Switzerland's B2G mandate has remained stable since its 2016 introduction. There are no announced plans to extend mandatory structured e-invoicing to B2B or B2C transactions at the federal level. For now, Swiss B2G e-invoicing stands as a contained obligation, limited to federal procurement contracts above the CHF 5,000 threshold.

Record retention. Regardless of whether invoicing is electronic or paper-based, Swiss businesses must retain all invoicing records for a minimum of 10 years under the Swiss Code of Obligations. For e-invoices, this means records must remain accessible, readable, and verifiable throughout the retention period.

How Switzerland's eBill System Works

eBill is Switzerland's national digital billing infrastructure, and the model has no direct parallel in other countries. Rather than sending invoices by post or email, billers transmit structured invoice data directly into the payer's e-banking portal. The recipient sees the full invoice details inside their online banking interface, reviews the amount and line items, and approves payment with a single click. No paper. No PDF attachment. No manual data entry or payment reference transcription.

The system is operated by SIX Group, Switzerland's financial market infrastructure provider (the same entity that runs the Swiss stock exchange and interbank payment systems). eBill launched in its current form in 2018, replacing the earlier Paynet service, and has since become the dominant digital billing channel for consumer-facing invoices across the country.

Adoption and Scale

The growth numbers illustrate why eBill matters for any business billing Swiss customers. SIX Group reports that eBill now serves over 3.5 million registered users, with 89% of users reporting they are rather or very satisfied with the service. That reach covers more than half of all Swiss households in just six years. On the infrastructure side, 95% of Swiss financial institutions support eBill, and over 10,000 companies actively issue invoices through the platform.

These figures reflect something structurally unusual: eBill is embedded in the banking system itself, not layered on top of it. When a Swiss consumer logs into their bank's online portal, eBill invoices appear alongside their account balances and transaction history. This native integration is what drives both the high adoption rate and the high satisfaction scores.

eBill Direct Debit

In mid-2025, SIX Group introduced eBill Direct Debit, extending the platform into recurring payment collection. With this feature, billers can set up automatic debiting once the payer grants consent through their e-banking interface. The invoice is still presented digitally for transparency, but payment collection happens automatically on the due date.

This combines two capabilities that are typically separate in other markets: digital invoice presentation and automated recurring payment. For billers handling subscriptions, monthly service fees, or regular utility charges, eBill Direct Debit eliminates both the paper invoice and the manual payment approval step in a single integration.

B2C Dominance, B2B Growth

eBill is most firmly established in the B2C space. Utilities, insurance companies, telecom providers, and health insurers were early adopters, and these sectors account for the bulk of transaction volume today. B2B adoption is growing as more companies recognize the settlement speed and reduced processing costs, but the system's core strength remains consumer billing.

For international companies operating in Switzerland, this distinction matters. If your Swiss entity bills consumers, eBill is effectively a required channel to meet customer expectations. If you operate purely in B2B, eBill is a valuable option but not yet the default.

Becoming an eBill Biller

Companies that want to issue invoices through eBill connect to the network through a certified eBill network partner (SIX maintains a registry of authorized partners). The integration involves connecting the biller's invoicing system to the eBill infrastructure via the partner's platform, followed by a testing and certification process. The setup effort is higher than generating QR-bills, which is why eBill adoption is concentrated among mid-to-large billers with established digital invoicing workflows.

Why eBill Has No International Equivalent

Other countries have e-invoicing mandates, Peppol networks, or tax authority clearance models. None of them have a billing system integrated directly into the national banking infrastructure at this scale. eBill is not a government mandate or a tax compliance tool. It is a market-driven billing channel that succeeded because Swiss banks collectively adopted it and embedded it into their consumer-facing platforms. That combination of banking integration, voluntary adoption, and nationwide reach is unique to Switzerland and is the single biggest factor that distinguishes Swiss e-invoicing from every other country's approach.

eBill vs QR-Bill: Understanding the Difference

QR-bill and eBill solve fundamentally different problems, yet the two are routinely conflated in discussions about Swiss digital invoicing. The core distinction is straightforward: QR-bill is a payment instrument, while eBill is an invoicing channel. Confusing them leads to flawed compliance assessments and misguided IT project scoping.

A QR-bill is a standardized payment slip carrying a Swiss QR Code that encodes structured payment information such as the creditor's account number, payment amount, currency, and reference number. It replaced the legacy ESR (orange) and red payment slips in 2022, unifying Swiss payment transactions under a single format. The underlying invoice itself may still be a paper letter, a PDF attachment, or any other document format. What the QR code standardizes is the payment data, not the invoice content. The payer scans the QR code with a banking app, confirms the pre-filled payment details, and authorizes the transfer. For a deeper look at the technical specifications, see our guide to Swiss QR-bill format and payment requirements.

eBill operates on an entirely different model. Rather than digitizing the payment slip while leaving the invoice as a separate document, eBill eliminates the standalone invoice altogether. The biller transmits structured invoice data directly into the payer's e-banking interface through the SIX eBill infrastructure. The recipient reviews the invoice details within their online banking portal and approves payment with a single action. There is no document to open, no QR code to scan, and no manual data entry at any stage.

In practice, the two systems are complementary rather than competing. A Swiss business typically deploys both: eBill for customers who have registered for digital invoice delivery through their bank, and QR-bills for everyone else. This dual approach is common because QR-bill adoption is near-universal across Swiss payment transactions, while eBill, despite rapid growth past 3.5 million registered users, is concentrated among larger billers with the technical infrastructure to connect to the eBill network. Smaller businesses and sole proprietors often rely on QR-bills exclusively because the integration effort for eBill is substantially higher.

One practical timeline consideration: the November 2025 requirement mandating structured address data (rather than free-text fields) in QR codes applies specifically to QR-bill, not to eBill. Businesses maintaining QR-bill workflows need to ensure their invoicing software outputs addresses in the structured format with separate fields for street, building number, postal code, and city. eBill transmissions already carry structured data by design, so this particular deadline is irrelevant for the eBill channel.

Dimension	QR-Bill	eBill
Function	Payment instrument (standardized payment slip)	Digital invoicing channel
Invoice delivery	Separate document (paper, PDF, or other format)	Invoice data delivered directly to payer's e-banking
Payer action	Scan QR code, confirm payment	Review invoice in banking portal, approve with one click
Adoption scope	Near-universal for Swiss payment transactions	3.5M+ users, primarily larger billers
Integration effort	Low (generate QR code on invoice)	Higher (connect to SIX eBill infrastructure)
Document required	Yes (invoice exists as a separate artifact)	No (invoice data is the delivery)

Accepted E-Invoicing Formats and Standards

Switzerland does not mandate a single e-invoicing format. Instead, the country accepts multiple standards, each serving a distinct purpose depending on the transaction type, trading partner, and whether the invoice crosses a border. This multi-format reality distinguishes Switzerland from markets like Italy or France, where a single national standard dominates.

Here are the principal formats and standards in use across the Swiss e-invoicing ecosystem:

SwissDIGIN is the domestic e-invoicing standard developed specifically for the Swiss market. Maintained by the SwissDIGIN Forum, it defines how structured invoice data should be exchanged between Swiss businesses in B2B transactions. Organizations operating primarily within Switzerland will encounter SwissDIGIN requirements most frequently in their domestic supply chains.

UBL XML (Universal Business Language) is the international standard for structured e-invoicing adopted across dozens of countries. In Switzerland, UBL is accepted for B2G submissions to the federal government and is the default format for cross-border trade with partners who require structured data exchange. Its broad international adoption makes it a practical choice for Swiss exporters.

For public sector data exchange, eCH-011 provides the Swiss e-government standard. Developed under the eCH association's framework for standardizing government IT, it defines invoice data structures used in cantonal and federal procurement contexts. Organizations bidding on public contracts should verify whether their submission platform requires eCH-011 compliance.

Cross-border interoperability is handled through Peppol BIS and the OpenPeppol network. Although Switzerland is not an EU member state, it participates in OpenPeppol as a full member, giving Swiss businesses access to the same standardized delivery infrastructure used across Europe. Peppol adoption is growing for both B2G submissions and international B2B transactions, particularly with trading partners in EU countries where Peppol is becoming mandatory.

ZUGFeRD/Factur-X takes a different approach as a hybrid format, embedding machine-readable XML data inside a human-readable PDF. GS1 Switzerland has officially endorsed ZUGFeRD/Factur-X since 2020, recommending it as a practical bridge for organizations transitioning away from pure PDF invoicing. The format allows recipients to process invoices automatically while still viewing them as familiar PDF documents. See our detailed guide to how the Factur-X hybrid PDF/XML format works for coverage of its profile levels and technical structure.

EN-16931 is the European e-invoicing standard developed under EU Directive 2014/55/EU. Switzerland maintains partial alignment with EN-16931 but is not legally bound by the EU directives that require its adoption. In practice, Swiss companies trading with EU partners will need EN-16931 compliance for those transactions, even though no Swiss law imposes it domestically.

The practical consequence of this multi-format landscape is that a single Swiss business may need to send SwissDIGIN invoices to domestic clients, Peppol BIS documents to EU trading partners, and UBL XML submissions to the federal government. Organizations handling high invoice volumes across these channels often rely on automated tools for processing electronic invoice formats or middleware that normalizes incoming documents into a single internal format. GS1 Switzerland continues to promote standardization efforts aimed at reducing this complexity, but for now, format versatility remains a core requirement for Swiss e-invoicing implementation.

EU ViDA and Cross-Border E-Invoicing for Swiss Companies

Switzerland is not an EU member state, and no Brussels directive applies directly to Swiss domestic invoicing. But Swiss companies that trade across EU borders cannot treat this as someone else's problem. The EU's VAT in the Digital Age (ViDA) initiative is reshaping how invoices flow between businesses throughout Europe, and Swiss exporters and importers sit squarely in the path of that change.

The core mechanism is the Digital Reporting Requirements (DRR) framework under ViDA. By July 2030, EU member states will implement mandatory e-invoicing for intra-Community B2B transactions. When a Swiss company sells goods or services to an EU-based buyer, that buyer's country may require the transaction to be documented through a structured e-invoice conforming to EU standards. The obligation falls on the EU party, but the practical effect reaches the Swiss seller: if your French customer needs a machine-readable EN 16931 invoice to satisfy their domestic mandate, you need to be able to produce one.

The patchwork problem compounds this. EU member states are not waiting for the 2030 DRR deadline to act. France begins phased mandatory e-invoicing from 2026. Germany follows from 2027. Italy has operated its Sistema di Interscambio since 2019. Poland, Spain, Belgium, and Romania each have their own timelines and platform requirements. A Swiss manufacturer exporting to customers in four EU countries could face four distinct e-invoicing regimes, each with different technical specifications, validation rules, and reporting portals.

For Swiss companies, the practical takeaway is format readiness. Domestic invoicing may continue using SwissDIGIN, eBill, or QR-bills for the foreseeable future, but EU-facing systems need to handle EN 16931 (the European semantic data model for e-invoices) and Peppol BIS Billing 3.0 as baseline formats. Many ERP vendors already support these standards, but companies that have configured their systems purely for Swiss domestic requirements will need to verify and likely extend their capabilities.

There is no domestic Swiss B2B e-invoicing mandate on the horizon, and the Swiss Federal Council has not signaled plans to introduce one. But that absence of a domestic mandate should not translate into inaction. For Swiss companies with EU trade exposure, the practical preparation steps are:

Inventory your EU trading partners by country and identify which will face e-invoicing mandates soonest (France 2026, Germany 2027)
Verify your ERP or invoicing system can generate EN 16931 and Peppol BIS Billing 3.0 output for those partners
Map country-specific platform requirements where applicable (e.g., France's Chorus Pro for B2G, Germany's XRechnung validation)
Establish a timeline for testing structured e-invoice exchange with your highest-volume EU partners before their mandates take effect

The EU ViDA impact on Switzerland is indirect but unavoidable for any business with cross-border European trade.

Swiss E-Invoicing FAQ

Is e-invoicing mandatory in Switzerland?

For business-to-government (B2G) transactions, yes. Federal suppliers with contracts above CHF 5,000 have been required to submit structured e-invoices since 2016. For B2B and B2C transactions, e-invoicing remains entirely voluntary. Switzerland has not announced any mandate timeline for the private sector.

What is eBill and how does it work?

eBill is Switzerland's national digital billing infrastructure, operated by SIX Group. Billers send invoices directly into a payer's e-banking portal, where the recipient can review, approve, and pay with a single click. The system has surpassed 3.5 million registered users and handles both recurring and one-time invoices across consumer and business accounts.

What is the difference between eBill and QR-bill?

QR-bill is a payment instrument that replaced the traditional orange and red payment slips. It standardizes payment data in a printed or digital QR code but does not transmit the invoice itself. eBill is a digital billing channel that delivers the full invoice electronically through the recipient's e-banking. The two serve different functions and complement each other rather than competing.

What e-invoicing formats does Switzerland accept?

Swiss e-invoicing supports several structured formats: SwissDIGIN, UBL XML, eCH-011, Peppol BIS Billing 3.0, and the hybrid ZUGFeRD/Factur-X standard. There is partial alignment with the European EN 16931 norm, particularly through Peppol and ZUGFeRD profiles. The right format depends on whether you are invoicing government entities, domestic businesses, or cross-border partners.

Does EU ViDA apply to Switzerland?

The EU's VAT in the Digital Age (ViDA) regulation does not apply to domestic Swiss transactions. However, Swiss companies that trade with EU-based partners will need to accommodate EU-mandated e-invoicing formats as individual member states roll out their requirements through 2030. Preparing for Peppol and EN 16931 compatibility now reduces the integration burden when those obligations take effect.

What is the 10-year archival requirement?

Swiss businesses must retain all invoicing records, including e-invoices, for a minimum of 10 years. This obligation aligns with general Swiss bookkeeping and accounting retention rules under the Swiss Code of Obligations. Records must remain accessible, readable, and verifiable throughout the retention period.
