Signal · Agentic checkout
AI checkouts charge different fees. They all need the same facts from you.
AI assistants that let customers buy inside a chat don’t agree on what the business pays: PYMNTS reported in January 2026 that Shopify merchants pay a 4% fee on ChatGPT checkout sales, while Microsoft says Copilot Checkout takes no commission, as of 14 June 2026. They also differ on who is the seller of record and where the payment sits. Our read: fees will keep moving, but every one of these checkouts depends on your facts being current and correct.

Five checkouts, five different answers on fees and control
Public pages from the companies and independent reporting, read side by side. “Seller of record” means the business legally making the sale and answering for it.

Instant Checkout leaves the business responsible
With Instant Checkout and the Agentic Commerce Protocol a purchase can finish inside ChatGPT, while the business stays responsible for orders, payment, fulfilment and accepting the order.
PYMNTS · 21 January 2026
A 4% fee on ChatGPT checkout sales
PYMNTS reported in January 2026 that Shopify merchants pay a 4% fee on ChatGPT checkout sales, on top of existing payment fees. Our read: it’s a charge for reach, and terms like it can change. OpenAI’s checkout shift, reported in March (below), came later, so check the fee is still current before you rely on it.
Microsoft · product page
Copilot Checkout takes no commission, as of 14 June 2026
Microsoft says Copilot Checkout takes no commission or affiliate fee, as of 14 June 2026, that merchants stay the seller of record and that payments run on existing payment networks. Microsoft puts it in the present tense, so it’s a current position, not a permanent one.
PayPal · 28 October 2025
Store Sync and Agent Ready build on your setup
PayPal bases Store Sync and Agent Ready on merchants’ own catalogues and existing PayPal settings, with merchants staying the seller of record and keeping control of their brand and customer messages.

OpenAI moves checkout towards merchant apps
Digital Commerce 360 reported the shift, citing stock, tax, pricing and the constant updates they need as reasons a central checkout was hard to scale.
What they share: each assumes the business’s catalogue, prices, availability and acceptance are current and correct.
Who sets what
Three layers in an AI purchase. One is yours.
The checkout and its fee
- Set by
- The assistant
Each assistant sets its own fee, who is seller of record and where the payment is held. These differ today and can change tomorrow.
Payment and settlement
- Set by
- Payment networks and providers
Existing payment networks move and settle the money, on a route the business or its payment provider chooses.
Your current facts, authorised by you
- Set by
- You
The catalogue, prices, availability, rules, locations and accepted payments an agent reads before it acts. Every checkout relies on them; none of them supplies them.
Our read: no checkout has won, and fees are the part that moves. Your facts travel with the customer to every one of them.
Your side
Six facts every AI checkout reads
They have to be right when the customer asks, not when your last update went out.
What you sell
Described clearly and consistently, so a request matches the right item on any assistant.
Price and availability
Today’s price, and whether the item or slot is really available now.
Your rules
Deposits, cancellations, who qualifies, and when you can accept an order.
Which location
Hours, service area and the details of the site the request is for.
How you take payment and deliver
The payment and fulfilment routes you actually support, so the agent doesn’t guess.
Current and authorised by you
Fresh, and traceable to you as their source. Stale or unauthorised facts fail at the moment that matters.
Four ways building around one checkout backfires
A brand rebuilds around one checkout and its fee, then a second assistant launches on different terms and the brand is least ready where new demand arrives.
A team reads a no-commission stance as permanent and plans around it, though the company describes it in the present tense and can change it.
An operator treats the chat as the control point and lets seller-of-record details, rules and location facts drift, so the agent reads stale facts at the moment of purchase and the order fails.
A business spends its effort negotiating one assistant’s fee instead of keeping facts right that cut failures on every assistant at once.
What to do now
Five things to do as checkouts multiply
Keep your facts current and authorised
Catalogue, prices, availability, rules, location details and accepted payments, so the same facts serve any assistant your customers use.
List the AI checkouts your customers reach
Note each one’s fee, who is seller of record and where the payment sits, as they stand today.
Choose your payment and delivery routes per location
Decide which ones you support at each site, so an agent sends customers down a route you can honour.
Treat today’s fees as a snapshot
A fee or a no-commission stance can change; check the terms again before you plan around them.
Check what assistants say about each location
As hours, prices and availability change, make sure the answers customers get still match.

Where this comes from
Built from public pages and reporting, all checked on 14 June 2026; each development’s own date and the date we checked it are kept apart. That your business facts are the lasting control point is our reading, not a claim by any company named. Obenan doesn’t process payments, settle transactions, run a checkout or route transactions; isn’t a payment provider, acquirer or seller of record; doesn’t own or implement a checkout or payment protocol; and has no partnership, endorsement, integration, pilot or commercial relationship with OpenAI, Microsoft, PayPal, Shopify or any other company named. Nothing here says your facts are certified or committable by any assistant, network or protocol.
