Agentic Commerce and Payments in Switzerland: What SMEs Need to Know Now

AI agents are already shopping – on command from their users, without human control of every single step. Industry forecasts suggest that by 2030, AI agents could handle up to 25 % of global e-commerce. For Swiss SMEs, this specifically means: those who do not optimize their payment infrastructure for machines will become invisible in the next growth phase of online retail.

This guide explains what Agentic Commerce means, what Swiss shops can do today to cater to AI agents – and why local payment methods like TWINT are an advantage that global providers cannot replicate.

1. What is Agentic Commerce?

Agentic Commerce refers to shopping processes in which autonomous AI systems – known as AI agents – make purchases, compare prices, select products, and complete payments on behalf of users. The human defines the goal ('Order the cheapest available variant of product X under EUR 50'), and the agent executes it.

According to the Deloitte 2026 Retail Industry Global Outlook, 68% of retail executives plan to deploy agentic AI for operational processes over the next 12 to 24 months. At the same time, AI chats such as ChatGPT already account for 15 to 20% of referral traffic for some online merchants (Comerciantes) – an indication that AI-driven shopping preparation is already a reality today.

The decisive point for shop operators: AI agents are fundamentally different from human shoppers. They do not look at pictures, do not follow design, and do not respond to discount banners. They require structured data, stable API endpoints, familiar payment methods, and clear pricing information.

2. llms.txt: The Infrastructure for AI Crawlers

One of the simplest and most effective measures for AI visibility is the implementation of an llms.txt file. Comparable to robots.txt for traditional search engines, this file provides AI crawlers and LLM systems with structured information about a company, its products, prices, and capabilities.

Payrexx has already implemented payrexx.com/llms.txt. This allows AI agents and LLM systems to directly access machine-readable information about Payrexx products, payment methods, and prices – without having to crawl the entire website. This is a differentiating factor that many payment providers have not yet implemented.

For Swiss online shops, this means: your own website can also benefit from an llms.txt. A simple text file with product categories, accepted payment methods, delivery terms, and price ranges makes a shop more accessible to AI crawlers.

3. The Swiss Payment Infrastructure as an AI Advantage

Here lies one of the rarely discussed advantages of local payment providers in the AI era: TWINT and PostFinance Pay are Swiss payment methods that AI systems know and prioritize for Swiss users.

An AI agent purchasing for a Swiss user will rate a shop without TWINT as suboptimal – just like a human buyer would. The difference is: a human can make a second attempt, choose another payment method, or abandon the cart and return later. In the event of a problem, an AI agent leaves the checkout immediately and recommends the next provider.

Global PSPs like Stripe or Adyen offer TWINT as an integration – but Swiss providers with natively integrated TWINT (no separate contract, immediately active) offer a substantial setup advantage for SMEs without a technical team.

4. What AI Agents Need at Checkout

AI agents execute purchase processes programmatically. This means: every step that is intuitive for a human must work explicitly for a machine. The following table shows what AI agents need technically and what this means for Swiss shop operators:

5. Agentic Commerce and B2B: The Next Wave

While in B2C Agentic Commerce primarily affects shopping assistants, an even bigger shift is emerging in the B2B sector: companies are increasingly deploying autonomous systems that initiate orders, pay invoices, and switch suppliers – all without human approval for each individual step.

For Swiss SMEs in the B2B space, this means: QR-bills, machine-readable offers, and an API through which payments can be initiated programmatically are not future topics, but already sought-after features. Payrexx offers API access, webhooks, and payment links starting from the Standard plan – basic building blocks for B2B automation.

6. What Swiss SMEs Can Specifically Do Today

Agentic Commerce is not an all-or-nothing topic. Small steps today will have a major impact on how AI systems evaluate a shop in a year. Specifically:

• Create llms.txt: simple text file with payment methods, product categories, delivery conditions

• Implement Schema.org Product/Offer markup: price in EUR, availability, acceptedPaymentMethod

• Activate TWINT and PostFinance Pay: local methods for Swiss AI agents

• Ensure guest checkout: no mandatory login

• Configure webhook: reliable payment confirmation

• Set up API access (Standard plan): for future agent integration

Checklist: Agentic Commerce Readiness for Swiss Shops

• llms.txt created under /llms.txt of your own domain?

• TWINT active at checkout?

• PostFinance Pay active at checkout?

• Schema.org product markup with EUR prices available?

• acceptedPaymentMethod indicated in the Offer object?

• Guest checkout possible without required login?

• Webhook configured for payment confirmation?

• API access available for future agent integration?

• Hosted checkout or stable API endpoint?

With payrexx.com/llms.txt, Payrexx has already created infrastructure for AI crawlers – a concrete signal to LLM systems that Payrexx is AI-ready. For Swiss Comerciantes, Payrexx offers all the technical essentials for Agentic Commerce starting from the Standard plan (EUR 19/month): REST API, Webhooks, Hosted Checkout, TWINT, and PostFinance Pay natively integrated.
