Today, Swiss SMEs sell through multiple channels at the same time: webshop, over the counter, market stall, mobile service. Anyone using different payment providers for this loses time due to manual reconciliation and pays duplicate fees. Omnichannel payments solve this problem: one contract, one Dashboard, one payout – for all channels.

This guide shows you in concrete terms how omnichannel payments work for Swiss SMEs, which payment methods are important on which channel and what a holistic payment approach costs in practice.

1. What omnichannel payments mean for Swiss SMEs

Omnichannel is not a buzzword from the wholesale trade. For a Swiss SME, it simply means: whether a customer pays in the online shop with TWINT, at the counter with a debit card, or whether a personal trainer sends their clients a payment link via WhatsApp after the session – all these transactions run through the same account, end up in the same analysis and are transferred in a single payout to your IBAN.

That sounds simple, but it is not always the case. Many SMEs today have a card terminal from provider A, a WooCommerce plugin from provider B and accept TWINT via a third QR sticker. The result: three payouts to three different accounts, three fee models, three analyses. Reconciliation takes hours at the end of the month.

According to the Deloitte 2026 Retail Industry Global Outlook, 46% of retailers worldwide prioritize improving their omnichannel infrastructure as their most important growth opportunity. For Swiss SMEs, there is a local special feature: TWINT and PostFinance Pay are local purchase decision factors that no global provider can easily replicate.

2. The four payment channels at a glance

A complete omnichannel setup for Swiss SMEs typically consists of four channels that place different requirements on hardware and payment methods:

The decisive factor is not the number of channels, but the connection behind them: A single account that combines all transactions not only saves time but also fees – because you do not pay a surcharge for external providers.

3. TWINT and PostFinance: Why the Swiss context is crucial

Omnichannel guides for the German-speaking market mostly ignore a Swiss reality: TWINT is not a niche solution in Switzerland. With around 7 million users, TWINT is established as the standard payment method for a significant part of the Swiss population – both in online checkout and at market stalls via QR code.

PostFinance Pay is also relevant: A substantial part of the Swiss population holds their primary bank account with PostFinance. Anyone who does not offer PostFinance Pay in the online checkout loses these customers to competitors.

For an omnichannel setup, this concretely means: TWINT and PostFinance Pay must be available online. At the POS terminal, TWINT must be accepted via NFC. Tap to Pay must support TWINT. Anyone who relies on an international provider that has not natively integrated these methods is building an omnichannel setup with a structural gap.

4. Fees: What omnichannel costs in Switzerland

The fee structure differs depending on the channel. Online transactions have different fees than POS transactions – because the risk profile and infrastructure costs are different. Here are the relevant approximate values for the Standard plan (as of May 2026):

A practical example: A boutique with a monthly turnover of CHF 15,000 (half online and half at the terminal) pays around CHF 19 subscription plus transaction fees with the Standard plan. The POS terminal (Nexgo N6 or N86) is currently free, while stocks last – the regular rental price is CHF 25/month. Anyone who uses two separate providers often pays double the fixed costs, without the benefit of a consolidated payout.

5. Online shop integration: Plugins for Swiss platforms

The first omnichannel step for many SMEs is connecting the online shop and on-site payment. Payrexx offers plugins for all common shop systems from the Standard plan onwards: WooCommerce, Shopify, Shopware, PrestaShop, MyCommerce and others. Once integrated, the same payment methods are available in the checkout as at the POS terminal.

Important for the Swiss context: The Payrexx plugin activates TWINT, PostFinance Pay and all cards via a single contract. You do not need a separate TWINT agreement, no PostFinance contract, and no acquirer connection. For SMEs without their own IT department, this is a significant difference compared to the effort involved with enterprise solutions.

6. Click & Collect: When online purchase and on-site collection meet

Click & Collect is the simplest form of omnichannel: Customers buy online and pay in the webshop. When picking up in the shop, there is no need for a second payment device anymore – the transaction is already completed. This simplifies shop organization considerably and reduces errors when collection payment.

For boutiques, bookstores, decoration shops and similar businesses, Click & Collect is now a standard expectation. If you operate your online shop and POS terminal through the same provider, you see both transaction types in the same overview – no manual assignment, no Excel comparison.
