How does a small business get ready for agentic commerce?
Agentic commerce is software buying on a customer's behalf, and it has already shipped. To get ready, a small business needs spotless structured product data, a platform that supports the ACP and UCP protocol rails, and plain, structured returns and delivery terms an agent can read.
Section 01
Being bought from, not just recommended
Everything so far was about being recommended. This chapter is about being bought from — by software, on a customer's behalf, without them ever seeing your beautiful homepage. It sounds like science fiction. It shipped.
You do not need to memorise the acronyms. You do need to know that there are competing rails and you can't pick a side — ChatGPT transacts through one, Google's AI surfaces through another, and most retailers will end up supporting both.
Section 02
The four protocol rails, in plain English
- ACP — Agentic Commerce Protocol
- OpenAI with Stripe. Handles checkout inside ChatGPT. Shopify merchants can switch on the ChatGPT sales channel from the admin.
- UCP — Universal Commerce Protocol
- Google's, announced January 2026 with Shopify, Etsy and Walmart. Covers discovery through to order management; agents find your capabilities at a well-known address on your site.
- AP2 — Agent Payments Protocol
- The "is this agent allowed to spend this money" layer, backed by the card networks and handed to the FIDO Alliance. Your payment provider's problem, mostly. Ask them anyway.
- MCP — Model Context Protocol
- Anthropic's open standard, now under the Linux Foundation. The plumbing agents use to talk to tools and systems — including, eventually, yours.
Section 03
What an SME should actually do about it
- Get your product data spotless. Titles, prices, stock, variants, shipping, returns, images. An agent won't ring you to clarify — it'll pick the shop whose data it understands. This is the whole ball game.
- Ask your platform one question. "Which agentic commerce protocols do you support, and what do I need to switch on?" If you're on Shopify the answer is short and pleasant. If your dev built it in 2016, the answer is a project.
- Write your returns and delivery terms in plain, structured language. Agents read policy pages to decide risk. Vague policies lose to clear ones.
- Accept that measurement is behind reality. As of early 2026 you can sell through these channels far more easily than you can attribute the sale. Don't wait for perfect reporting to show up.
