Definition
Agentic checkout is a purchase flow where an AI agent places the order on a shopper’s behalf instead of the shopper filling in a checkout form. Instant Checkout is OpenAI’s named implementation of the pattern inside ChatGPT, while agentic checkout is the general category several platforms are building toward. The merchant still fulfils the order.

At a glance
- An agentic checkout sends the order through an interface built for software, not through your web pages.
- Payment usually works by passing a token, so the agent never holds a raw card number.
- The merchant stays the seller of record, with fulfillment, tax and refunds unchanged.
- Whether you can support one today depends on your commerce platform, not on your marketing team.
Where the order actually gets placed
Three parties are in the flow instead of two: the shopper, the agent, and you.
The shopper describes what they want. An AI shopping agent builds a shortlist, and when the shopper confirms a choice, it does not open your website. It calls interfaces you publish: a feed for price and stock, a checkout call to create the order, a payment step that hands over a token.
The Agentic Commerce Protocol sets out one version of that handshake, keeping checkout and delegated payment separate so the agent never sees raw card details.
You accept or reject the order, take the money, and ship. What you no longer own is the screen where the decision happened.
Losing the last screen you control
Your checkout page is the last place you get to influence a sale. Free shipping thresholds, a loyalty prompt, the add-on that pays for the campaign. None of that renders in an agentic flow.
The agent sees price, availability, shipping cost, return window and whatever else your feed exposes. Those fields are the entire basis of comparison.
A brand that competes on experience gets flattened into a row in a table. A brand with a better price, faster delivery or a clearer returns policy gets a fairer hearing than it ever got on a crowded category page. Which of those happens to you is settled in your feed, not in your design system.
Decide your position before a platform decides it for you
Most brands have no say yet in whether agentic checkout exists. You do have a say in what you are ready for.
- Ask your commerce platform what is live. Your storefront, payments provider and marketplace integrations are doing the implementation. Get a straight answer on what ships, what is in beta and what needs your opt-in.
- Work out the unit economics of an agent-placed order. Platform fee, no email captured, a likely higher return rate on something nobody browsed twice. Set your margin floor before someone else sets it.
- Fix the data the agent reads. Price, stock, shipping cost, delivery window, return window. Product feed optimization is the dull half of this and the half that decides whether you get chosen.
- Choose the categories you would accept it on. Consumables and replenishment are the easy yes. Sizing and long consideration are a reasonable no for now.
- Keep one route to the customer. A packing insert, a warranty registration, a returns flow you own. If the assistant holds the relationship, the insert is your only introduction.
Agentic checkout vs the checkout you built
| Your own checkout | Agentic checkout | |
|---|---|---|
| Who completes the form | The shopper | The agent, from stored details |
| What moves the sale | Page design, upsells, urgency | Price, stock, delivery, returns |
| Data you receive | Email, behavior, consent | Order details, little else |
| Cost per order | Payment fees | Payment fees plus a platform fee |
Frequently asked questions
-
Is agentic checkout the same as Instant Checkout?
No. Instant Checkout is one product, OpenAI’s, running inside ChatGPT. Agentic checkout is the category it sits in, and other assistants are building their own versions. Treat Instant Checkout as the first live example, not the definition.
-
Do I pay a fee when an agent places the order?
Usually yes. OpenAI’s announcement of Instant Checkout says merchants pay a fee on completed purchases. Other implementations will set their own terms. Price it as a channel cost next to marketplace commission and paid acquisition, because it changes which products are worth listing.
-
Who handles a refund on an agent-placed order?
You do. In the implementations published so far the merchant stays the seller of record: your returns policy, your customer service, your tax obligations. The agent brokered the sale. It did not take over the contract.
-
How do I get my products eligible?
Eligibility runs through your commerce platform, not a form you fill in. Get your catalog accurate, then ask your platform how it enrols merchants. Anyone offering to list you for a fee is selling access they do not control.
-
Is this worth building custom integration for today?
For most brands, no. Volume is small, the specs are young, and an integration you write this quarter may need rewriting next quarter. The exception is a large merchant with spare engineering capacity in a replenishment category. Everyone else should get the feed right and let the platform do the rest.
