Swiss SMEs currently sell through multiple channels simultaneously: webshop, over the counter, market stall, mobile service. Anyone using different payment providers for this loses time due to 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 an integrated payment approach costs in practice.

1. What omnichannel payments mean for Swiss SMEs

Omnichannel is not just a wholesale buzzword. 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 client a payment link via WhatsApp after the session – all these transactions run through the same account, end up in the same evaluation, and are transferred in a single payout to your IBAN.

This 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 evaluations. Reconciliation costs 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 an additional local feature: 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 demands 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 usually 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 the market stall 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 means in concrete terms: online, TWINT and PostFinance Pay must be available. 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 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 benefit of a consolidated payout.

5. Online shop integration: Plugins for Swiss platforms

The first omnichannel step for many SMEs is integrating 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 through 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 required with enterprise solutions.

6. Click & Collect: When online purchase and on-site pickup 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 need for a second payment device – the transaction is already completed. This simplifies store organization considerably and reduces errors at the checkout.

For boutiques, bookstores, decoration shops, and similar businesses, Click & Collect is now a standard expectation. Anyone who operates an online shop and POS terminal through the same provider sees both transaction types in the same overview – no manual allocation, 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 online shop with Payrexx plugin (WooCommerce, Shopify, Shopware etc.)

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

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

• Verify Dashboard evaluations for all channels in a single view

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