The Practical Guide: Omnichannel Payments for Swiss SMEs – Online, in-store and mobile from a single source

Swiss SMEs now sell across multiple channels simultaneously: webshop, events, store counter, market stall, mobile service. Those who use different payment providers for this lose time through manual reconciliation and pay duplicate fees. Omnichannel payments solve this problem: one contract, one Dashboard, one payout – for all channels.

This guide shows you how omnichannel payments specifically 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 wholesale buzzword. For a Swiss SME, it simply means: whether a customer pays in the online shop with TWINT, at the shop counter with a debit card, or a personal trainer sends their client a payment link via WhatsApp after the session – all these transactions run through the same account, end up in the same reporting, and are transferred to your IBAN in a single payout.

That sounds simple, but it isn't always. 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 reports. Reconciliation costs hours at the end of the month.

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

2. An overview of the four payment channels

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

As of: October 2026

The deciding factor is not the number of channels, but the connection behind them: a single account that brings all transactions together 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 over 6 million users, TWINT is established as a 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. Those who do not offer PostFinance Pay in the online checkout lose these customers to competitors.

For an omnichannel setup, this specifically means: TWINT and PostFinance Pay must be available online. At the POS terminal, TWINT must be accepted – the customer scans the QR code on the terminal display for this. Tap to Pay must support TWINT (via QR code on the smartphone). Those who rely on an international provider that has not natively integrated these methods build 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 guide values for the Standard plan (as of October 2026):

A practical example: A boutique with a monthly turnover of EUR 15,000 (split equally between online and at the terminal) pays around EUR 19 subscription plus transaction fees on the Standard plan. The POS terminal (N910 Pro, Nexgo N6 or N86) costs EUR 25/month rental. Those who use two separate providers often pay twice as much in 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 more. Once integrated, the same payment methods are available at 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. There is no need for a separate TWINT agreement, no PostFinance contract, no acquirer integration. For SMEs without an in-house IT department, this is a significant difference compared to the effort involved with enterprise solutions.

6. Click & Collect: When online purchasing 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-store, a second payment device is no longer needed – the transaction is already complete. This significantly simplifies store organisation and reduces checkout errors.

For boutiques, bookshops, interior decoration shops, and similar businesses, Click & Collect is now a standard expectation. Those operating an online shop and POS terminal via the same provider see both transaction types in the same overview – no manual assignment, no Excel reconciliation.

Checklist: Setting up omnichannel payments for Swiss SMEs

• Take inventory of all active payment channels: online shop, terminal, Tap to Pay, payment links

• Check whether TWINT and PostFinance Pay are available across all relevant channels

• Connect the online shop with the Payrexx plugin (WooCommerce, Shopify, Shopware, etc.)

• Order a POS terminal or set up Tap to Pay on an Android device

• Use the consolidated weekly payout

• Review Dashboard reports for all channels in a single view

• Define the Click & Collect process: Is payment made online or at the collection counter?

Payrexx offers Swiss SMEs a complete omnichannel infrastructure from a single contract: online payments via plugins or API, POS terminals (N910 Pro, N6 or N86), Tap to Pay for Android, payment links, and QR Pay for mobile situations – all in one Dashboard with a consolidated payout. TWINT, PostFinance Pay, and all Swiss payment methods are natively integrated, without separate contracts with acquirers or payment providers. Find more information at payrexx.com.
