On January 11, 2026, Google unveiled the Universal Commerce Protocol (UCP) at the NRF conference - an open standard that enables AI agents to shop autonomously for users. What sounds like science fiction will become reality in the coming months. For e-commerce merchants, this means: Those unprepared will lose visibility and revenue to competitors.
What is Agentic Commerce?
Agentic Commerce describes a fundamental shift in online retail: Instead of searching, comparing, and buying themselves, users delegate these tasks to AI agents. The agent understands the request, researches options, compares prices, and executes the purchase autonomously - without the user ever visiting a shop.
A user tells Gemini: "Buy me new running shoes, size 10, under $150, delivery by Friday." The AI agent searches for matching products, compares reviews and prices, selects the best offer, and completes the checkout - fully automatically.
Handelsblatt reports that agentic AI in online retail could already have a market share of 20-30% within three to five years (Handelsblatt/Unzer). Market researchers predict that more than 50% of consumers will use AI shopping assistants by the end of 2026 (eMarketer).
The Universal Commerce Protocol (UCP) Explained
The Universal Commerce Protocol is an open standard that establishes a common language between AI agents, merchants, and payment providers. It was developed by Google in collaboration with Shopify, Target, Walmart, Etsy, Wayfair, and over 20 other partners - including Visa, Mastercard, Stripe, and Zalando.
Open Standard
Open source, compatible with existing protocols like A2A and MCP
End-to-End
From product search through checkout to post-purchase support
Secure
Tokenized payments, transaction audit trails
UCP works with defined Capabilities - individual functions like availability checking, price calculation, discount application, or payment processing. AI agents can automatically detect which capabilities a merchant supports and call them in a structured way.
Google's New Merchant Tools
Together with UCP, Google has introduced several new tools for merchants accessible through the Google Merchant Center:
| Tool | Function | Availability |
|---|---|---|
| Business Agent | Branded AI chat directly in search | Live since Jan 12, 2026 |
| Direct Offers | Exclusive discounts for ready-to-buy users | Pilot phase |
| New Data Attributes | Extended product fields for LLMs | Rollout ongoing |
The Business Agent is particularly interesting: It functions like a virtual sales associate that appears directly in Google Search. Merchants can train it with their own data and customize it to their brand. First partners like Lowe's, Michael's, and Reebok are already live.
What Merchants Need to Do Now
The good news: UCP doesn't require a complete technical overhaul. Integration primarily happens through the Google Merchant Center. However, requirements for product data are increasing significantly.
Unlike traditional keyword search, LLMs need rich contextual information. Thin product data leads to invisibility - no matter how good your shop otherwise is.
Google has introduced dozens of new data attributes in Merchant Center specifically relevant for AI agents. These go far beyond traditional keywords:
- Answers to common product questions
- Compatible accessories and alternatives
- Detailed technical specifications
- Usage scenarios and use cases
- Size and fit information
- Comparison data to similar products
Similar protocols like OpenAI's ACP even expect data refreshes every 15 minutes to keep price and availability current. For merchants without automated feed synchronization, this becomes a challenge.
Data Enrichment as Key to Success
AI-powered data enrichment is no longer just a nice-to-have, but becomes a critical success factor. Those investing in complete, structured product data today will be preferred by AI agents.
Product data requirements have fundamentally changed:
| Before (Keyword SEO) | Now (Agentic Commerce) |
|---|---|
| Titles with keywords | Natural language descriptions |
| Basic data (price, size) | Comprehensive attribute sets |
| Static feeds | Real-time synchronization |
| Categories | Usage scenarios & alternatives |
| Images | Images + structured product Q&A |
This is exactly what we already offer with our AI automation: Automatic enrichment of product data with AI, generation of product questions and answers, and real-time synchronization with Merchant Center.
UCP and Shop Systems: Who's Prepared?
Shopify natively supports UCP - not surprising since they're co-developers of the protocol. For other shop systems, it looks different:
| Shop System | UCP Status | Recommendation |
|---|---|---|
| Shopify | Natively supported | Activate & configure |
| Shopware | No native support yet | Optimize Merchant Center |
| WooCommerce | No native support yet | Improve feed management |
| Magento | No native support yet | Prepare API integration |
For Shopware shops, this means: Integration will likely happen through plugins and Merchant Center. Those optimizing their product data now and building a clean integration architecture are prepared.
Agentic Checkout: How Autonomous Purchasing Works
The actual paradigm shift lies in checkout: The user never visits the merchant's website. The AI agent handles the entire purchase process - from product selection to payment.
UCP offers two integration options:
Native Checkout
Direct API integration with Google AI Mode and Gemini - full agentic potential
Embedded Checkout
iFrame-based for special branding requirements - selected merchants only
Payment processing happens tokenized through established payment providers like Stripe, Visa, or Mastercard. The merchant remains Merchant of Record and retains full control over customer data and relationships.
Opportunities for Mid-Sized Businesses
Pascal Beij from payment provider Unzer sees great opportunities for mid-sized merchants: "Using Agentic AI gives mid-sized businesses the great chance to be seen in online retail without a huge advertising budget." (Handelsblatt)
AI agents evaluate products by relevance and data quality - not by ad budget. Those providing the best product information win - regardless of company size.
This shifts investment from advertising spend to data quality. For B2B merchants with complex products and technical specifications, this is a particular opportunity: Detailed product data is their natural competitive advantage.
OpenAI's Alternative: Agentic Commerce Protocol (ACP)
OpenAI is also working on their own standard: The Agentic Commerce Protocol (ACP) pursues similar goals as UCP, focusing on three core areas: Agentic Checkout, Delegated Payment, and Product Feed.
For merchants, this means: Convergence of these standards is likely. UCP is already compatible with existing protocols like A2A, AP2, and MCP. Those investing in structured product data today are prepared for both ecosystems.
Timeline: What Happens When?
- January 2026: UCP launch, first Business Agents live (USA)

- 2028-2030: Forecast 50-70% adoption of AI shopping assistants (eMarketer)
Development is rapid. Those starting to prepare their product data and optimize Merchant Center today have a decisive advantage.
Practical Steps to UCP-Readiness
Based on current requirements, we recommend the following steps for e-commerce merchants:
- Merchant Center Audit: Check your Google Merchant Center for completeness and errors
- Product Data Analysis: Identify gaps in your product attributes
- Feed Automation: Ensure price and availability data synchronize in real-time
- Start Enrichment: Add product questions, accessories, and usage scenarios
- Set Up Monitoring: Continuously monitor data quality
We analyze your shop and Merchant Center and show you specifically what steps you should take to prepare for Agentic Commerce.
Conclusion: Act Now, Don't Wait
Agentic Commerce is no longer a distant future vision - it's the present. Google's UCP is live, first merchants are already connected, and development will accelerate in 2026.
The good news for merchants: Preparation doesn't require massive technical changes. The focus is on data quality - and that's an investment that also pays off for traditional SEO and conversion optimization.
The bad news: Those who wait too long lose visibility. AI agents prefer merchants with complete, structured product data. Those who don't deliver it simply won't be recommended.
With Google Shopping, users search and buy themselves. With UCP, they delegate the entire process to an AI agent that autonomously researches, compares, and purchases - without the user visiting a shop.
No, integration primarily happens through Google Merchant Center. Product data quality is more important. Native Shopware plugins will likely be available in 2026/2027.
Add product questions and answers, accessory recommendations, detailed specifications, and usage scenarios. Our AI data enrichment automates this process.
On the contrary - mid-sized merchants can benefit because AI agents decide based on data quality, not ad budget. Good product data beats large marketing budgets.
Investment depends on your current product data state. A Merchant Center audit is the first step to quantify the effort. Contact us for an assessment.
Now. UCP is already live, and development is accelerating. Merchants starting today have a competitive advantage over those who wait.
