Your store is now open inside every AI
When someone asks ChatGPT for a product recommendation, your catalog is in the conversation. They browse, compare, and buy — all without leaving the chat. UCP makes it happen.
Find me a wireless charger under $40
I found the MagSafe Pro Charger — $29.99, 4.8★ rating, ships tomorrow
Order confirmed — arriving Thursday
Shopping is moving into conversations
Your customers are already shopping this way. They ask Gemini “What’s the best wireless charger under $40?” — and the AI doesn’t just answer. It searches catalogs, compares prices, and completes the purchase. All in the same conversation.
This is not a trend to watch. Shopify launched agentic storefronts across ChatGPT, Gemini, and Copilot in March 2026. Google, Walmart, and Stripe are backing the same protocol. If your store isn’t part of this, you’re invisible to the fastest-growing shopping channel on the planet.
AI conversations are the new front door to commerce.

Open Standard
What is UCP?
UCP is the open standard that lets AI assistants sell products on behalf of merchants. Co-created by Shopify and Google, backed by Walmart, Target, Stripe, and 30+ others — it defines how any AI agent discovers your products, builds a cart, processes payment, and confirms the order. One protocol, every AI platform. Nventory supports it out of the box.
Open Standard
No vendor lock-in, no gatekeepers
Merchant-First
Your brand, your data, your customers
Extensible
New AI platforms, same protocol
What this means for your store
Not just another integration. A fundamentally new way to reach buyers.
A new revenue channel
ChatGPT, Gemini, Copilot — each one becomes a storefront for your catalog. No listings to manage, no marketplace commissions cutting into your margins.
Real checkout, not just links
Customers don't get a link to click — they complete the entire purchase inside the AI conversation. No app switching, no cart abandonment.
Works with what you have
Your existing catalog, pricing, and fulfillment rules carry over. Flip one switch in your Nventory dashboard — nothing to rebuild, no migration.
Secure by default
Every transaction is authenticated with API keys, payments processed through Stripe, and you can test the entire flow in sandbox before going live.

UCP is the checkout standard — how AI agents pay. ACP is the discovery layer — how AI agents find your products. Enable both and your store speaks every AI agent’s language, end to end.

Our team can help you understand activation, sandbox testing, and how UCP fits into your existing sales channels.
Contact UsThe Universal Commerce Protocol is an open standard that lets AI assistants like ChatGPT and Google Gemini sell products on behalf of merchants. It standardizes how AI agents discover products, create checkouts, and process payments.
Both protocols enable AI agents to interact with your store, but they work at different levels. ACP is an application-level protocol for agent-to-catalog interactions. UCP is an open industry standard that provides a cross-platform checkout flow — so AI agents on any platform can complete real purchases using the same protocol.
UCP is designed to work with any AI assistant that implements the protocol. Current platforms include ChatGPT, Google Gemini, Microsoft Copilot, and more are being added regularly.
No. You can enable UCP directly from your Nventory admin dashboard. Choose your sales channel, connect your payment gateway, add your branding, and you’re live.
Payments are processed securely through Stripe using tokenized payment methods. Nventory supports sandbox mode so you can test the full checkout flow before going live. No raw payment data ever touches your server.
Not at all. UCP adds a new channel alongside your existing ones. Orders from AI assistants appear in your dashboard just like orders from Shopify, Amazon, or any other channel.
