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

Swiss SMEs sell through multiple channels simultaneously today: online shop, events, shop counter, market stall, mobile service. Anyone who uses 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 how omnichannel payments work in practice 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 a corporate 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 if 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 currently have a card terminal from provider A, a WooCommerce plugin from provider B, and accept TWINT through a third QR sticker. The result: three payouts to three different accounts, three fee structures, three reports. Reconciliation takes 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 particularity: TWINT and PostFinance Pay are domestic purchase-deciding 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:

As of: May 2026

The critical factor is not the number of channels, but the underlying connection: a single account that bundles all transactions saves not only 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 market stalls via QR code.

PostFinance Pay is also highly relevant: a substantial part of the Swiss population holds their primary bank account with PostFinance. If you do not offer PostFinance Pay in the 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. If you rely on an international provider that has not integrated these methods natively, you are 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 CHF 15,000 (half online and half at the terminal) pays around CHF 19 subscription 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 CHF 25/month. If you use two separate providers, you often pay 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 in-person payments. 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 under 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 involved with enterprise solutions.

6. Click & Collect: When online purchase and in-store 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 shop organisation considerably and reduces checkout errors.

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

• Connect your online shop using 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 cycle (weekly or monthly)

• Review Dashboard reports for all channels in a single view

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