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

Swiss SMEs now sell through multiple channels simultaneously: webshop, events, shop counter, market stall, mobile service. Businesses using different payment providers for each lose time through manual reconciliation and pay double fees. Omnichannel payments solve this problem: one contract, one dashboard, one payout – for all channels.

This guide shows you how omnichannel payments for Swiss SMEs work in practice, which payment methods are important on which channels, and how much a holistic payment approach costs in reality.

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 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, end up in the same evaluation, and are transferred to your IBAN in a single payout.

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 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. Overview of the four payment channels

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

As of: May 2026

The key is not the number of channels, but the connection behind them: a single account that consolidates 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 at the online checkout and at the market stall via QR code.

PostFinance Pay is also relevant: a substantial part of the Swiss population has their primary bank account with PostFinance. If you do not offer PostFinance Pay in your online checkout, you lose these customers to competitors.

For an omnichannel setup, this practically 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. Businesses choosing an international provider that does not have these methods natively integrated are building an omnichannel setup with a structural gap.

4. Fees: What omnichannel costs in Switzerland

The fee structure differs by 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 monthly sales of EUR 15,000 (half online and half at the terminal) pays around EUR 19 subscription fee plus transaction fees on 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. Businesses using two separate providers often pay twice the fixed costs without enjoying the benefits of consolidated payouts.

5. Online shop integration: Plugins for Swiss platforms

The first omnichannel step for many SMEs is connecting the online shop with in-store checkout. Payrexx offers plugins for all popular shop systems from the Standard plan: WooCommerce, Shopify, Shopware, PrestaShop, MyCommerce and more. 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, and no acquirer connection. For SMEs without their own IT department, this is a significant difference compared to the effort required for enterprise solutions.

6. Click & Collect: When online purchasing meets in-store pickup

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

For boutiques, bookstores, decoration shops, and similar businesses, Click & Collect is now a standard expectation. When running the online shop and POS terminal through the same provider, you can 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 if TWINT and PostFinance Pay are available on all relevant channels

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

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

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

• In Dashboard, review evaluations for all channels in one single view

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