Today, Swiss SMEs sell across multiple channels simultaneously: webshops, over the counter, market stalls, mobile services. Anyone using different payment providers for these loses time through manual reconciliation and pays double 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 wholesale buzzword. For a Swiss SME, it simply means: whether a customer pays with TWINT in the online shop, with a debit card at the counter, or whether a personal trainer sends their client a payment link via WhatsApp after the session – all these transactions run through the same account, land in the same analysis and are transferred to your IBAN in a single payout.

That sounds simple, but it is not always. Many SMEs today have a card terminal from provider A, a WooCommerce Plugin e-commerce 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 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 a local peculiarity: TWINT and PostFinance Pay are domestic 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:

Status: May 2026

The decisive factor is not the number of channels, but the connection behind them: a single account that bundles 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 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. Anyone who does not offer PostFinance Pay in the online checkout loses 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 via NFC. Tap to Pay must support TWINT. Anyone relying 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 guide values for the Standard plan (as of May 2026):

A practical example: a boutique with a monthly turnover of EUR 15,000 (half online and half at the terminal) pays around EUR 19 subscription plus transaction fees with the Standard plan. The POS terminal (Nexgo N6 or N86) is currently free of charge while stocks last – the regular rental price is EUR 25/month. Anyone using two separate providers often pays double the fixed costs without the advantage 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 in-person 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. There is no need for a separate TWINT agreement, no PostFinance contract, 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 come together

Click & Collect is the simplest form of omnichannel: customers buy online and pay in the webshop. When picking up in-store, there is no longer a need for a second payment device – the transaction is already completed. This simplifies shop organisation considerably and reduces checkout errors.

For boutiques, bookstores, decoration shops and similar businesses, Click & Collect is now a standard expectation. Those who operate their 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

• Inventory all active payment channels: online shop, terminal, Tap to Pay, payment links

• Check whether TWINT and PostFinance Pay are available on 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

• Set up a consolidated payout frequency (weekly or monthly)

• Review Dashboard analysis for all channels in one single view

• Define Click & Collect process: is payment made online or at the pick-up counter?
