The Practical Guide: Omnichannel Payments for Swiss SMEs – Online, in-store 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 these channels lose time with manual reconciliations and pay double fees. Omnichannel payments solve this problem: one contract, one Dashboard, one payout – for all channels.

This guide shows you in detail how omnichannel payments work for Swiss SMEs, which payment methods are important on each channel, and the practical costs of an integrated payment approach.

1. What omnichannel payments mean for Swiss SMEs

Omnichannel is not just a wholesale buzzword. For a Swiss SME, it simply means this: whether a customer pays in your 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 a session – all these transactions go through the same account, end up in the same reporting, and are transferred to your IBAN in a single payout.

It sounds simple, but it is not always the case. Today, many SMEs have a card terminal from provider A, a WooCommerce Plugin e-commerce from provider B, and accept TWINT through a third-party QR sticker. The result: three payouts into 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 specificity to consider: TWINT and PostFinance Pay are essential purchasing decision factors here, which 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, which have different requirements for hardware and payment methods:

The key is not the number of channels, but the connection behind them: a single account that aggregates all transactions saves not only time but also fees – because you do not pay extra fees 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 checkout online 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. Retailers who do not offer PostFinance Pay in their online checkout lose these customers to competitors.

Specifically for an omnichannel setup, this 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. Choosing an international provider that does not natively integrate these methods leaves you with a structural gap in your omnichannel setup.

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 differ. 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 on the Standard plan. The POS terminal (Nexgo N6 or N86) is currently free while stocks last – the regular rental price is EUR 25/month. Using two separate providers often means paying double 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 their 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 at 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, a PostFinance contract or a separate acquirer connection. For SMEs without their own IT department, this is a significant advantage compared to the effort involved with enterprise solutions.

6. Click & Collect: When online purchasing and in-person collection come together

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

For boutiques, bookshops, decoration stores and similar businesses, Click & Collect is now a standard customer expectation. Running your online shop and POS terminal through the same provider allows you to see both transaction types in the same overview – no manual assignment, no Excel reconciliation.

Checklist: Setting up omnichannel payments for Swiss SMEs

• Audit 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 an Android device

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

• Verify Dashboard analytics for all channels in a single view

• Define the Click & Collect process: will customers pay online or at the pickup counter?
