TWINT & Swiss E-Commerce Payment Methods 2026: PostFinance, Cards & Open Banking Guide

The 2026 Swiss Payment Landscape at a Glance

Few European countries have a payment mix as distinctive as Switzerland's. The cards below summarise the ten payment rails covered in this guide — keep them nearby as you read each deep-dive section.

1. TWINT — Switzerland's P2P Mobile Payment Champion

TWINT at a Glance

TWINT is, by every honest metric, the centre of gravity of Swiss e-commerce payments. The system originated as two parallel projects — Paymit from SIX Payment Services (UBS / Credit Suisse / ZKB consortium, 2014) and TWINT from PostFinance (2015) — which merged in April 2017 into the unified TWINT AG. By 2026 TWINT serves over 5 million active users in a country of 8.7 million, processes more than 700 million transactions per year and is owned jointly by UBS, Raiffeisen, Zürcher Kantonalbank (ZKB), PostFinance and the Swiss Cantonal Bank consortium. There is no comparable national mobile payment system in Western Europe.

The architecture is what makes TWINT uniquely Swiss: each user's TWINT app is tied directly to a Swiss bank account or prepaid CHF balance, so settlement is bank-to-bank, instant, and free of card-scheme fees. For merchants this means TWINT acceptance is consistently 30–50% cheaper than equivalent Visa or Mastercard acceptance — typically 1.1–1.4% of transaction value versus 1.8–2.5% for cards.

From a Swiss shopper's perspective, TWINT is a near-default for any mid-ticket online purchase. Independent surveys (Swiss Payment Monitor 2025, ZHAW) place TWINT's share of online mobile checkouts at 55–65%, ahead of all cards combined and well ahead of PayPal.

TWINT for E-Commerce — Two Flows

Merchants integrate TWINT through one of two flows. The first is a QR-code redirect: the checkout page renders a QR code and the shopper scans it with their TWINT app to confirm payment in seconds. The second is the UOF flow (User-on-File), in which the shopper enters their Swiss mobile number, receives a push notification from their TWINT app and confirms with biometrics — no QR scan required. UOF is the standard on mobile, QR is standard on desktop.

Both flows are EMV 3DS-equivalent from a strong-customer-authentication perspective, so they fall outside the EU PSD2/PSD3 SCA framework but still meet the FINMA-supervised Swiss equivalent.

TWINT Acceptance Channels

• Direct TWINT acquiring — open a TWINT merchant contract through TWINT AG; lowest fees, requires Swiss legal entity and CH IBAN.
• Stripe Switzerland — TWINT as a payment method since 2023, settles in CHF to a CH IBAN or via FX to EUR.
• Datatrans — Zurich-based Swiss PSP, one of the earliest TWINT integrations; deep cantonal-bank relationships.
• Wallee — Winterthur-based Swiss payment gateway, popular for Shopify and WooCommerce sites.
• Worldline (ex-SIX Payment Services) — long-standing TWINT acquirer; strong with large retailers like Migros and Coop.

2. Visa & Mastercard — The Universal Card Backbone

Cards in Swiss E-Commerce

Visa and Mastercard remain indispensable in Switzerland — not because Swiss shoppers prefer them (TWINT outpaces both combined for domestic purchases) but because cross-border traffic from Germany, Austria and France relies on them. Combined card share of Swiss e-commerce checkouts in 2026 sits at ~25–30%, of which Mastercard slightly leads Visa (largely thanks to Maestro / Mastercard Debit penetration on Swiss bank cards).

Major Swiss issuers — UBS, Raiffeisen, ZKB, PostFinance, Cornèr Bank, Viseca, Swisscard — issue both Visa and Mastercard products, and most include Apple Pay / Google Pay tokenisation by default.

Acquiring in Switzerland

The Swiss card-acquiring market is concentrated. The dominant acquirers are Worldline (which absorbed SIX Payment Services in 2018), Stripe Switzerland, Adyen, Datatrans and Concardis (now Nexi Group). Each provides Visa + Mastercard acceptance with CHF settlement to a Swiss IBAN, EMV 3DS2 enforcement, and integrated tokenisation for repeat customers.

Typical Card Acquiring Fees 2026

Fees include a fixed transaction component (typically CHF 0.20–0.35) on top of the percentage. Switzerland is not covered by the EU Interchange Fee Regulation (IFR), so domestic CH interchange is set by Swiss schemes rather than capped at the 0.20/0.30% EU ceilings — this is a subtle but important reason Swiss card fees run slightly higher than EU averages.

3. PostFinance Card — The Yellow Swiss Debit

From Postcard to PostFinance Card

PostFinance AG is the financial-services arm of Swiss Post, established as a separate joint-stock company in 2013. It is fully owned by the Swiss Confederation, holds a Swiss banking licence and is supervised by FINMA. PostFinance issues a yellow debit card historically known as Postcard, now rebranded the PostFinance Card, that taps into the famous PostFinance current accounts used by over 2.5 million Swiss residents.

The card was a pure domestic-Swiss product for decades, processed through PostFinance's own acquiring network and accepted at virtually every Swiss POS terminal. Since 2020, PostFinance has been migrating the card onto the Debit Mastercard rails so it can be used internationally and online, while preserving the legacy "PostFinance Card" branding for domestic acceptance.

PostFinance Card in E-Commerce

The PostFinance Card carries roughly 7–9% of Swiss e-commerce checkout share — small versus TWINT but very sticky, particularly among older demographics, federal-government workers and rural Swiss customers. PostFinance shoppers tend to be high-trust, low-chargeback and concentrated in groceries, household goods and government-adjacent services.

For merchants, PostFinance Card acceptance comes bundled with most Swiss acquirer contracts (Worldline, Datatrans, PostFinance Checkout). PostFinance also operates its own checkout platform — PostFinance Checkout — which natively supports the PostFinance Card, TWINT, Visa, Mastercard, PayPal and Klarna in a single API.

4. PayPal Switzerland — Cross-Border Default Wallet

PayPal's Long History in Switzerland

PayPal has been live for Swiss merchants and shoppers since 2008, operated by PayPal (Europe) S.à r.l. et Cie, S.C.A. out of Luxembourg with a CH branch for local compliance. By 2026 PayPal counts roughly 2 million Swiss account holders and a checkout share of approximately 5–7% — smaller than in Germany or the UK, primarily because TWINT and Stripe carve out the mobile-wallet niche, but indispensable for cross-border CH ↔ DE / AT / FR / IT shoppers.

Strengths of PayPal in CH

• Multi-currency wallets — Swiss users can hold CHF, EUR and USD balances in a single account, switching by checkout.
• PayPal Buyer Protection — the de-facto "safety net" Swiss shoppers reach for on unfamiliar international stores.
• PayPal Pay Later — 3-instalment BNPL launched in Switzerland in 2023, settled in CHF with no interest within the 3-instalment window.
• SEPA + SWIFT payout — merchants can withdraw to CH IBAN, EUR IBAN or USD account with FX visibility.

PayPal Fees in CH 2026

PayPal Switzerland fees in 2026 are 2.49% + CHF 0.55 for domestic CH transactions on the standard merchant tier, with reductions to 1.99% + CHF 0.55 for higher-volume merchants. Cross-border surcharges add 0.5–1.5% depending on currency. FX spreads on PayPal currency conversion are notably wide (~3.5%) — Zunapro routes PayPal payouts via a "keep currency" rule to avoid the FX hit when settling back to a CHF IBAN.

5. Apple Pay & Google Pay — Tokenised Mobile Wallets

Apple Pay in Switzerland

Apple Pay launched in Switzerland on 7 July 2016, making CH one of the very first European countries with Apple Pay support — ahead of Germany (2018) and Spain (2016). Initial issuer support came from Cornèr Bank, Bonus Card and Swiss Bankers Prepaid; today every major Swiss issuer (UBS, Raiffeisen, ZKB, PostFinance, Viseca, Swisscard) tokenises Visa and Mastercard for Apple Pay. Apple Pay handles both online checkouts (via the Apple Pay JS API or Stripe / Adyen / Worldline integrations) and in-store contactless via NFC.

Google Pay in Switzerland

Google Pay followed in March 2018, again starting with Cornèr Bank and UBS issuance and now covering all major Swiss issuers. Android device penetration in CH is roughly 45% — significantly lower than the EU average due to Apple's exceptionally strong iPhone share in the high-income Swiss market — so Google Pay's checkout share is correspondingly smaller than Apple Pay's.

Wallet Share and Trends

Combined Apple Pay + Google Pay share of Swiss e-commerce checkouts sits at roughly 10–14% in 2026, with year-on-year growth above 30%. Apple Pay dominates the mix at roughly 2:1 vs Google Pay. The wallet flows are not really "new" payments — they tokenise an underlying Visa or Mastercard — but they radically improve mobile conversion (typical uplift: 8–15% on iOS checkouts) thanks to biometric one-tap confirmation.

Implementation

Apple Pay and Google Pay are activated at the PSP level rather than via a direct merchant contract. Stripe Switzerland, Adyen, Worldline, Datatrans and Wallee all expose both wallets as a toggle once you complete the Apple Pay merchant identifier (MerchantID) registration with Apple. Zunapro pre-registers the MerchantID on your behalf and surfaces both wallets in the checkout in a single step.

6. Stripe Switzerland — Unified PSP for CH Merchants

Stripe's Swiss Entry

Stripe launched in Switzerland in 2018, operating through Stripe Payments Europe Ltd. with a Zurich branch for local compliance and CHF settlement. By 2026 Stripe has become the de-facto default payment stack for new Swiss e-commerce projects — particularly for SaaS, marketplaces and direct-to-consumer brands — because of the breadth of methods supported through a single API.

Methods Available Through Stripe in CH

• Visa, Mastercard, American Express, JCB, Discover, UnionPay
• TWINT — added 2023, full CHF settlement
• Apple Pay, Google Pay — automatic wallet tokenisation
• SEPA Direct Debit — for EU-based recurring billing customers
• Klarna — Pay-in-30 + 3-instalment, CHF settlement
• Sofort / EPS / iDEAL / Bancontact — for DACH and Benelux cross-border

Stripe Fees in Switzerland 2026

Stripe Switzerland settles to CHF or EUR IBANs with a 7-day payout window by default (Stripe Express). Their Radar fraud-protection engine is included on the standard tier and tunes specifically for Swiss BIN ranges and TWINT velocity signals.

7. Klarna BNPL — Buy on Invoice, Swiss Style

Klarna in Switzerland

Klarna entered the Swiss market in 2020, partnering initially with Galaxus, Digitec and Interdiscount. By 2026 Klarna is offered by virtually every major Swiss retailer — Manor, Coop, Migros (selected categories), Mediamarkt, About You, H&M — and counts roughly 1 million Swiss users. Checkout share of Klarna across Swiss e-commerce sits at 4–6%, with much higher penetration in fashion (sometimes >15% of checkouts).

The Three Klarna Flavours in CH

• Pay in 30 days (Rechnung kauf) — the most popular variant in Switzerland. Swiss shoppers have historically loved post-paid invoicing (the old "auf Rechnung" model from offline retail), so Klarna's invoice flow lands on familiar cultural ground.
• Pay in 3 instalments — interest-free 3-month split, settled in CHF.
• Klarna Financing — 6 / 12 / 24-month financing with regulated interest, suitable for high-ticket electronics and furniture.

Klarna Fees and Risk

Klarna charges Swiss merchants approximately 2.5% + CHF 0.35 on Pay-in-30 invoice transactions, slightly higher for Pay-in-3. The crucial economic point for Swiss merchants is that Klarna absorbs the credit risk on Pay-in-30 — the merchant is paid in full within 14 days regardless of whether the shopper ultimately pays Klarna. For categories with traditionally high "auf Rechnung" exposure (fashion, electronics), Klarna effectively monetises the risk you previously carried in-house.

8. Crypto Payments — Switzerland the Crypto Nation

Crypto Valley and Beyond

Switzerland is one of the most crypto-friendly jurisdictions on earth, anchored by the famous "Crypto Valley" around the Canton of Zug — home to the Ethereum Foundation, Cardano, Polkadot/Web3 Foundation, Bitcoin Suisse, ShapeShift and dozens more. FINMA was the first major financial regulator to issue clear guidelines distinguishing payment tokens, utility tokens and asset tokens (the 2018 ICO Guidelines, updated 2023), and the Swiss DLT Act of August 2021 created bespoke legal infrastructure for tokenised securities.

Banks That Accept Crypto

• Bitcoin Suisse — Zug-based crypto broker / custodian since 2013; merchant payment service (Bitcoin Suisse Pay) launched 2020.
• AMINA Bank (formerly SEBA Bank, rebranded 2024) — Zug-based FINMA-licensed bank covering crypto + traditional finance.
• Sygnum Bank — Zurich + Singapore-licensed; the first regulated digital-asset bank globally.
• PostFinance — launched crypto trading for clients in 2024 via partnership with Sygnum.

Municipal Acceptance

The City of Zug has accepted Bitcoin and Ether for tax payments and municipal fees since 2021, and Lugano's "Plan ₿" programme has accepted Bitcoin, Tether (USDT) and the city's own LVGA token for tax + commerce since 2022. Several other cantons run pilot programmes for crypto-denominated cantonal services.

Practical Merchant Acceptance

Swiss e-commerce merchants typically accept crypto through Bitcoin Suisse Pay, BitPay, Coinify or Mt Pelerin — each provides instant settlement in CHF to a Swiss IBAN, so the merchant has no crypto exposure unless they explicitly opt to retain it. Fees are typically 1.0–1.5% with no chargebacks (crypto transactions are final).

9. Open Banking — bLink / Common API (CH is not the EU)

Switzerland Is Not in the EU

The EU's PSD2 (in force since 2018) and the upcoming PSD3 + Payment Services Regulation (PSR), formally proposed in June 2023 and expected in late 2026, do not apply directly to Switzerland. Switzerland is neither an EU nor EEA member, so EU-level mandatory Open Banking obligations do not bind Swiss banks. Yet Swiss customers and Swiss FinTech startups still expect modern, API-based access to bank data — and the Swiss banking industry has responded with a voluntary domestic standard.

SBA Common API and bLink

The Swiss Bankers Association (SBA / SwissBanking) defined the Common API standard in 2018 — a reference specification for account-information services (AIS) and payment-initiation services (PIS) modelled loosely on the Berlin Group's NextGenPSD2 framework but adapted to Swiss legal context. SIX Group (operator of the SIX Swiss Exchange and Swiss financial market infrastructure) operationalised it in 2023 as the bLink platform, a regulated hub through which licensed third-party providers can access participating Swiss banks via standardised contracts.

As of 2026, more than 30 Swiss banks are live on bLink — UBS, Raiffeisen, ZKB, the Cantonal Banks, several private banks — and a growing roster of TPPs (third-party providers) offer account-aggregation, multi-banking and PIS flows on top.

Differences vs PSD3

• Voluntary, not mandatory — Swiss banks join bLink on a commercial basis; no regulator forces them.
• FINMA-supervised TPPs — FinTech licence (BankG art. 1b) or banking licence required for PIS.
• Commercial contracts — TPPs sign bilateral contracts with each participating bank; bLink standardises the contracts.
• Use cases — multi-banking aggregation, e-billing (eBill via PostFinance), corporate cash-management, lending underwriting.

Open Banking and E-Commerce

For e-commerce specifically, Open Banking PIS through bLink can power a "pay directly from your Swiss bank account" checkout button that competes with TWINT on cost (~0.5–0.8% per transaction) — but adoption remains early; TWINT's user-experience lead is hard to displace. We expect Open-Banking-initiated direct payments to capture meaningful share only by 2027–2028 as the EU PSD3 ecosystem matures and Swiss banks follow.

10. QR-Rechnung — The Swiss B2B Invoice Standard

The 2022 Transition

Switzerland's most important payments reform of the last decade was the migration from the legacy orange (ESR) and red (ES) payment slips to the new QR-Rechnung (QR-bill). The parallel-run period ended on 30 September 2022; since 1 October 2022, QR-Rechnung has been the only valid Swiss invoice payment format. Every B2B invoice issued in Switzerland in 2026 must carry a Swiss QR code, the creditor's CH IBAN or QR-IBAN, and (for structured references) a QRR (QR Reference) or SCOR (Structured Creditor Reference) field.

How QR-Rechnung Works

A QR-Rechnung is a standard A4 invoice with a Payment Section (105 × 210 mm) at the bottom containing the Swiss QR code (with the embedded Swiss Cross logo). The shopper opens any Swiss banking app — UBS, Raiffeisen, ZKB, PostFinance, Cantonal Bank, Migros Bank, Neon, Revolut Switzerland — scans the QR code, and the entire payment is pre-populated: amount, beneficiary, IBAN, reference. The payer confirms with biometrics; settlement is via SIC (Swiss Interbank Clearing) the same day.

Three Reference Models

• QRR (QR Reference) — replaces the old ESR reference; 27 digits; used when the creditor has a QR-IBAN.
• SCOR (ISO 11649) — international structured creditor reference; used for cross-border CH ↔ EU invoicing.
• Without reference (NON) — free-text "additional information" field; lowest-friction for ad-hoc invoices.

QR-Rechnung in E-Commerce

For B2C e-commerce, QR-Rechnung is the engine behind "Kauf auf Rechnung" (buy on invoice) — the Swiss shopper checks out, an electronic invoice with QR code is emailed or posted, and the shopper pays within 30 days. This flow remains hugely popular in CH (estimated 15–25% of mid-ticket B2C orders outside fashion). For B2B, it's effectively 100% of standard invoicing.

Zunapro generates compliant QR-Rechnung invoices automatically with the correct Swiss QR code, IBAN, reference (QRR/SCOR/NON) and MwSt breakdown at 8.1% / 2.6% / 3.8% — fully validated against the SIX Group QR-bill style guide.

Swiss Payment Methods — Fees Comparison Table 2026

The single most useful artefact for choosing which payment methods to offer is a side-by-side fee view. The table below summarises 2026 typical fees and key characteristics for each rail.

Payment Method	Typical Fee	Settlement	Share / Notes
TWINT	1.1% – 1.4%	CHF · same-day	~62% mobile · 5M+ users · CH-only
Visa / Mastercard	1.4% – 3.2% + CHF 0.30	CHF / EUR · T+1 – T+7	~28% · cross-border essential
PostFinance Card	0.8% – 2.0%	CHF · same-day	~8% · CH-only · loyal base
PayPal	2.49% + CHF 0.55	CHF / EUR / USD	~6% · cross-border safety net
Apple / Google Pay	same as underlying card	via card rails	~12% combined · mobile uplift
Stripe (CH)	1.4% + CHF 0.30	CHF · 7-day default	Unified PSP · TWINT included
Klarna	2.5% + CHF 0.35	CHF · 14-day net	~5% · invoice / 3-instalment
Crypto	1.0% – 1.5%	CHF instant · no chargebacks	Niche but Swiss-friendly
Open Banking PIS (bLink)	0.5% – 0.8%	CHF · same-day	Early; ~<1% share
QR-Rechnung	Bank transfer cost only	CHF · SIC same-day	~100% B2B · 15–25% B2C

Reading the table: TWINT is structurally the cheapest meaningful e-commerce rail for Swiss merchants; cards are necessary for cross-border; Apple/Google Pay piggyback on cards but boost mobile conversion; Klarna shifts credit risk off your balance sheet at a fee premium; QR-Rechnung is unique to CH and dominates B2B. The pragmatic 2026 stack is TWINT + Visa/Mastercard + Apple/Google Pay + PayPal + Klarna for B2C, plus QR-Rechnung for B2B.

Swiss Legal Framework 2026 — FINMA, MwSt, Consumer Law

FINMA — The Federal Regulator

FINMA (Eidgenössische Finanzmarktaufsicht / Swiss Financial Market Supervisory Authority) is the integrated federal regulator for Swiss banks, insurers, securities firms and payment institutions, established by the Financial Market Supervision Act of June 2007 (FINMAG). Every Swiss bank issuing TWINT, PostFinance Card, Visa or Mastercard is FINMA-supervised; Stripe Switzerland, Adyen and Datatrans operate under either a FINMA FinTech licence (BankG art. 1b) or under a partner bank's licence. The Swiss National Bank (SNB) separately supervises systemically important payment systems including SIC (Swiss Interbank Clearing).

Swiss Bankers Association (SBA / SwissBanking)

The Swiss Bankers Association (SBA), founded in 1912 and headquartered in Basel, is the umbrella industry body representing 260+ Swiss banks and bank-adjacent institutions. SBA does not regulate per se — that's FINMA — but it defines industry-wide standards (the Common API for Open Banking; the QR-Rechnung specification with PostFinance and SIX; the self-regulatory code of conduct on tax compliance). For merchants, the SBA is the source of truth for industry-wide payment standards.

MwSt — Swiss VAT

Switzerland's value-added tax is called Mehrwertsteuer (MwSt) in German, Taxe sur la valeur ajoutée (TVA) in French and Imposta sul valore aggiunto (IVA) in Italian, administered by the ESTV (Eidgenössische Steuerverwaltung). Standard rate is 8.1% since 1 January 2024 (raised from 7.7% to part-fund the AHV pension scheme), with reduced rates of 2.6% for food, books, medicine, newspapers and 3.8% for accommodation.

Merchants with annual worldwide turnover above CHF 100,000 must register for Swiss MwSt and charge it on supplies to Swiss customers. Foreign mail-order merchants delivering low-value (sub-CHF 65) goods into Switzerland have been required to register since 1 January 2019 if their annual Swiss turnover from such goods exceeds CHF 100,000 — the so-called "mail-order rule".

Consumer Protection — UWG, DSG, CO

• UWG (Bundesgesetz gegen den unlauteren Wettbewerb) — Unfair Competition Act; bans deceptive pricing, dark-pattern subscriptions and misleading promotions.
• DSG (Bundesgesetz über den Datenschutz) — revised Data Protection Act effective 1 September 2023, broadly aligned with EU GDPR but slightly more permissive; FINMA + FDPIC oversight.
• CO (Obligationenrecht) — Code of Obligations; defines distance-sale rights. There is no statutory EU-style 14-day right of withdrawal in CH for online B2C — Swiss law is more contract-freedom-oriented. Most reputable CH merchants nonetheless offer 14–30 day voluntary returns to match shopper expectations.

3DS and Strong Customer Authentication

Switzerland is outside the EU PSD2 SCA mandate, but in practice Swiss card issuers and acquirers apply EMV 3DS2 by default, with biometric authentication on Apple Pay / Google Pay tokens. TWINT and PostFinance Card are SCA-equivalent by design (PIN + biometrics in-app). FINMA's circulars on operational risk and the Banking Ordinance frame fraud-prevention expectations for Swiss PSPs.

Swiss Logistics, Fulfilment & Payment Touchpoints

Swiss Post — Backbone of Domestic Delivery

Swiss Post (Die Post) handles roughly 185 million parcels per year through its Swiss Post / PostLogistics network and is the dominant delivery partner for Swiss e-commerce. Its checkout-payment touchpoint is the PostFinance Card and TWINT-via-PostFinance flows; for returns, PostShop in-store drop-off is bundled into every major Swiss e-commerce platform.

The Courier Stack

• Swiss Post / PostLogistics — dominant; bundled PostFinance Card payment.
• DHL Express Switzerland — international + premium B2C.
• DPD Switzerland — strong cross-border DACH B2C.
• FedEx Switzerland — high-value cross-border, US-bound.
• Planzer — large-package + B2B distribution.

Payment-on-Pickup Patterns

Cash on delivery has fallen below 2% of Swiss e-commerce volume by 2026. The replacement pattern is Klarna Pay-in-30 + QR-Rechnung emailed after dispatch, which retains the "pay after I've seen it" psychology Swiss shoppers still value, with none of the cash-handling cost. Zunapro automates the dispatch → Klarna / QR-Rechnung flow trigger end-to-end.

Cross-Border DACH & EU from Switzerland

The DACH Market from a Swiss Base

Swiss merchants enjoy an unusual advantage: cultural and linguistic proximity to Germany (83M) and Austria (9M), on top of the Italian-speaking Ticino and the French-speaking Romandie. From a payments perspective, this means a Swiss merchant must always offer DE/AT-friendly methods alongside TWINT: Klarna Sofort (DE/AT favourite), Giropay (DE), EPS (AT), SEPA Direct Debit and the standard Visa/Mastercard rails.

The Cross-Border Payment Stack

• Domestic CH: TWINT, PostFinance Card, Visa/Mastercard, Apple/Google Pay, Klarna invoice
• DE customers: Klarna Sofort, Giropay, SEPA, PayPal, cards
• AT customers: EPS, Klarna, PayPal, cards
• IT/FR customers: PayPal, Carte Bancaire (FR), cards, SEPA
• Multi-currency settlement: CHF / EUR via Stripe Switzerland or Adyen

How to Set Up Swiss Payments — 2026 Step-by-Step

1. Choose Your Payment Mix (Decision Tree)

• Domestic Swiss B2C, all categories → TWINT + Visa/Mastercard + Apple Pay
• Fashion / lifestyle → add Klarna Pay-in-30 + PayPal
• High-ticket electronics, furniture → add Klarna Financing + QR-Rechnung post-pay
• Crypto-native or Crypto Valley audience → add Bitcoin Suisse Pay
• B2B → QR-Rechnung + eBill as primary, cards as fallback
• Cross-border DACH → add Klarna Sofort + Giropay + EPS via Stripe / Adyen

2. Swiss Legal Entity or Foreign Set-Up

You have three legal-entity options for accepting Swiss payments:

• Einzelfirma (sole proprietorship) — set up in days via the cantonal commercial registry, lowest overhead, full personal liability.
• GmbH (Gesellschaft mit beschränkter Haftung) — limited liability, CHF 20,000 minimum share capital, ~2 weeks registration.
• Foreign entity with Swiss MwSt registration — keep your existing company, register for Swiss MwSt with ESTV (CHF 100,000 turnover threshold), sell into CH with no Swiss establishment.

For TWINT direct acquiring, a Swiss entity is required. For TWINT via Stripe Switzerland, a foreign entity is acceptable but conversion is meaningfully better with a domestic CH IBAN.

3. MwSt Registration with ESTV

Once your annual worldwide turnover crosses CHF 100,000, MwSt registration with ESTV is mandatory. The registration flow:

• Apply online via the ESTV portal (estv.admin.ch)
• Receive your Swiss UID (Unternehmens-Identifikationsnummer) and MwSt-Nummer
• Configure your checkout for 8.1% standard / 2.6% reduced / 3.8% accommodation
• File quarterly MwSt returns electronically

Zunapro auto-applies the correct MwSt rate per SKU and produces quarterly ESTV export files.

4. QR-Rechnung Setup

Obtain a QR-IBAN from your Swiss bank (if using QRR references) and configure Zunapro's invoice templates with your name, CH IBAN, QR-IBAN, MwSt number and the Swiss QR code generator. Every B2B invoice will include the QR-Rechnung payment section in the correct 105 × 210 mm format.

5. Connect via Zunapro (10-Minute Integration)

1. Sign in to Zunapro and open the Switzerland module
2. Connect each payment method — paste API keys for TWINT (direct or via Stripe), cards, PayPal, Klarna and PostFinance Checkout into the respective tiles
3. Configure MwSt — 8.1% default with per-category overrides
4. Enable QR-Rechnung — single toggle, then upload your CH IBAN
5. Go live — first sync completes in roughly 10 minutes; all payment buttons render in your checkout
