Online shopping is entering a new era. Customers no longer want to click through endless menus, fill out forms, or juggle carts. They want speed, simplicity, and answers in real time. That’s exactly what ChatGPT’s new Instant Checkout feature delivers.

For merchants on BigCommerce, this is more than just a new tool—it’s the foundation of Agentic eCommerce, where AI-powered assistants don’t just recommend products, they complete the sale.

What Is Instant Checkout in ChatGPT?

Instant Checkout is the next step in conversational commerce. Instead of browsing a website, shoppers can now ask ChatGPT for product recommendations in plain language.

Here’s how it works:

  • A customer types or says: “Show me the best wireless earbuds under $150.”
  • ChatGPT responds with curated product options.
  • The shopper clicks Instant Checkout and completes the purchase in seconds.

No cart juggling. No abandoned sessions. Just a direct path from question to purchase.

This is powered by the Agentic Commerce Protocol (ACP)—a framework that allows AI agents to connect product catalogs, recommendations, and checkout flows seamlessly. It’s not just a feature; it’s a shift in how eCommerce will operate.

Why This Matters for BigCommerce Merchants

The stakes are high. Research shows that nearly 70% of online shopping carts are abandoned before checkout. That means for every 10 potential customers who add products to their cart, only 3 actually complete the purchase.

Conversational commerce is already proving to be a solution. In fact, global spending through conversational commerce channels is projected to reach $290 billion in 2025 . That’s a massive opportunity for merchants who adopt early.

For BigCommerce merchants, Instant Checkout means:

  • Faster conversions – Every extra click costs sales. Instant Checkout removes those clicks.
  • Mobile-first experience – Shoppers on phones don’t want to type in endless details.
  • Higher satisfaction – A smooth checkout means fewer abandoned carts.
  • Visibility in conversational search – If your catalog isn’t indexed, you won’t show up.
  • Competitive advantage – Early adopters will set the standard while others scramble.

The Catch: Merchants Must Be Signed Up

Here’s the key detail most merchants don’t realize: you must be signed up and properly indexed to even be considered for this feature in ChatGPT.

That means your product catalog has to be structured and synced to ChatGPT in a very specific way. If it isn’t, ChatGPT won’t surface your products when customers ask for recommendations.

This is where frontrunning matters. The brands that move first will dominate conversational search results, while others are left invisible.

As of today, ChatGPT has announced that this new feature will first roll out to Etsy stores (with Shopify stores to follow short after), but that doesn’t mean that BigCommerce merchants have to be left behind. ChatGPT’s “Agentic Commerce Protocol” is an open standard and this means that a bridge or connector can be built and implemented for BigCommerce stores.

Trepoly Is Building the Bridge Today

Trepoly is already developing the integration that connects BigCommerce catalogs to ChatGPT’s Instant Checkout. Our work ensures:

  • Catalog indexing that meets ChatGPT’s strict requirements
  • Plug-and-play integration with BigCommerce checkout URLs

What Agentic eCommerce Really Means

The term Agentic eCommerce describes a future where AI agents don’t just answer questions—they act on behalf of the customer. Instead of browsing, comparing, and checking out manually, shoppers will increasingly rely on AI to:

  • Recommend the right product
  • Apply discounts or loyalty rewards
  • Complete the purchase instantly

The Agentic Commerce Protocol (ACP) is the backbone of this shift. It ensures that product data, pricing, and checkout flows are structured in a way that AI agents can understand and act on.

For merchants, this means preparing your catalog and checkout systems now—because once ACP becomes the standard, late adopters will be left behind.

The Bottom Line

The future of eCommerce isn’t just faster checkouts—it’s agentic commerce, where AI assistants guide the entire buying journey. BigCommerce merchants who act now will lead the way, while others scramble to catch up.

Trepoly, the leading ecommerce development agency in agentic commerce, is making sure you don’t just keep pace—you set the pace.
