Google has rolled out a new shopping feature in the U.S. that lets people add products from different retailers to a single cart and check out once, inside both Google Search and the Gemini app. The move pushes Google further into territory once owned by marketplaces like Amazon — and it changes how a shopper might encounter a small business's products before they ever reach the business's own website.
What happened
Universal Cart works by pulling product listings from multiple merchants into one shopping session. A user searching for, say, a desk lamp and a pair of headphones could add both to the same cart even if they come from two unrelated stores, then complete one checkout flow rather than bouncing between sites. The feature is live now across Search and Gemini for U.S. users.
This builds on years of Google trying to make itself a shopping destination rather than just a traffic router. Earlier efforts included Google Shopping Actions and Google Express, both of which Google shut down after a few years when merchant and consumer adoption didn't justify the operating cost. The company has since leaned on its Merchant Center product feed system, which lets retailers list inventory directly in Search results without a dedicated storefront.
Universal Cart appears to extend that same feed infrastructure, meaning retailers already using Merchant Center listings are likely eligible for inclusion without extra setup. What's new is the checkout experience itself — consolidating purchases across sellers into one transaction, rather than Google simply linking out to each retailer's own cart and payment page.
The timing isn't incidental. OpenAI launched an instant checkout feature inside ChatGPT last year, letting users buy directly from retailers like Etsy and Shopify-powered stores without leaving the chat. Perplexity and Amazon's own AI shopping assistant, Rufus, have pushed similar ideas. The common thread: AI companies want to own the moment of purchase, not just the moment of search.
Why it matters
This is part of a broader pattern of AI platforms trying to compress the shopping journey into fewer steps and fewer websites. For years, a customer would search, click through to a retailer's site, browse, and then buy. Tools like Universal Cart aim to shrink that into one continuous interaction that never requires leaving Google's ecosystem.
That shift raises a familiar tension: convenience for the shopper versus control for the merchant. When checkout happens on a platform rather than a retailer's own site, the retailer has less visibility into the customer relationship — fewer emails captured, less control over the post-purchase experience, and more dependence on the platform's rules for visibility.
What this means for small businesses
If your business already lists products through Google Merchant Center, it's worth checking whether your feed is accurate and complete, since that's likely the gateway into Universal Cart. Outdated pricing, missing images, or incomplete product data could mean exclusion or a poor customer experience inside a checkout flow you don't fully control.
The bigger practical question is what Google charges for transactions processed this way and how much customer data flows back to the merchant. Historically, Google has been inconsistent about fees and feature longevity in its commerce efforts — several past shopping products were discontinued within a few years. Businesses relying heavily on this channel should treat it as a supplemental sales path, not a replacement for their own site and customer list.
There's also a visibility angle: as AI shopping tools get better at bundling products from multiple sellers automatically, ranking and recommendation logic becomes more important than it's ever been. Small retailers with sparse or poorly tagged product data may simply not surface at all.
What to watch
Watch whether Google discloses transaction fees or revenue-sharing terms for sales completed through Universal Cart, and whether the feature expands to Google's AI Overviews or voice search. Also track how OpenAI, Amazon, and Perplexity respond — if multiple platforms converge on bundled, cross-retailer checkout, the standard for how small businesses list products online could shift quickly.
The bottom line
Universal Cart adds another checkout path that bypasses a retailer's own website, so small businesses already using Google's product feed tools should audit their listings now rather than wait for the feature to expand.
