Agentic commerce just moved from slideware to shipping software. In the last three weeks: Google introduced the Universal Commerce Protocol (UCP) and started buy‑flows in AI Mode; Microsoft and PayPal launched Copilot Checkout; Stripe detailed its Agentic Commerce Protocol (ACP) and Agentic Commerce Suite (ACS); Amazon brought Alexa+ to the web at alexa.com; and Lenovo unveiled Qira, its cross‑device personal AI. If you run ecommerce, your catalog, policies, and checkout now need to be legible to agents—not just websites.

This 48‑hour plan helps you go live quickly without breaking SEO or your existing stack. It assumes you’re on Shopify, WooCommerce, BigCommerce, or a composable setup with a PIM/OMS.

Who this is for

• Founders and ecommerce leaders who want to capture early agentic demand in Google AI Mode, Gemini, Copilot, ChatGPT, and Alexa+.
• Growth/SEO teams prepping for a world where agents pull facts from your catalog, not your hero copy.
• Engineering/ops teams who need a pragmatic, low‑risk rollout path.

Day 0: Prerequisites (90 minutes)

1. Merchant eligibility: Confirm a verified Google Merchant Center (GMC) account with accurate business info, shipping, and tax settings. If you’re on Shopify, verify your Google & YouTube channel is healthy.
2. Policies live and crawlable: Make sure returns, warranty, shipping, and privacy pages are public, linked in your footer, and indexable.
3. Payments: Ensure you support at least one of Google Pay, PayPal, or Stripe for downstream compatibility with UCP/ACP‑powered checkouts. Google has said U.S. eligibility comes first, with PayPal support “soon.”

Hours 1–6: Fix product identity and schema

Agents need unambiguous products and policies. Start here:

1. Stabilize product IDs: Use a single, canonical product ID across your PIM, feed, and storefront. Map SKUs/variants cleanly. Avoid reusing IDs across seasons.
2. Add complete identifiers: Where relevant, include gtin, mpn, brand, color, size, and material in feeds and on‑page schema.
3. Publish policies in structured data: Add MerchantReturnPolicy and clear delivery estimates. If you offer warranties, include WarrantyPromise details.

    }
  }
}

Ship this for your top 100 SKUs first. Make sure every product page renders valid JSON‑LD and that your feed contains the same values.

Hours 6–18: Make your catalog legible to UCP, ACP/ACS, and Copilot

You have two realistic paths in 2026 Q1: “use what’s already there” or “stand up agent endpoints.”

Path A — Leverage existing listings (fastest)

• UCP (Google AI Mode & Gemini): Focus on GMC quality. UCP‑powered checkout starts on eligible product listings; strong IDs, price, tax, and shipping data are non‑negotiable. Read Google’s latest retailer post on UCP and AI Mode here.
• Copilot Checkout: If your platform is supported, confirm enrollment with your commerce provider or payment partner (PayPal/Shopify/Stripe). Microsoft’s rollout (Jan 8, 2026) enables purchase inside the chat—no site visit.
• Alexa+ on the web: With Alexa.com live to early‑access users, ensure your product pages and FAQs answer common questions succinctly; Alexa+ increasingly extracts answers and then hands off to purchase options.

Path B — Stand up agent endpoints (future‑proof)

• Stripe ACP (build‑it): Implement ACP endpoints so agents can create checkout sessions against your current stack. Start with Stripe’s spec and examples here.
• Stripe ACS (host‑it): Use ACS to host ACP for you and syndicate your catalog to supported agents with minimal plumbing. Overview here. Early enterprise adoption with commercetools is underway.

Hours 18–30: Harden answers for Business Agents and chat surfaces

Google’s Business Agent is surfacing in Merchant Center for U.S. retailers. Treat it like a 24/7 sales associate that quotes your site and feed verbatim.

1. Write canonical answers: Add short, scannable FAQs to product and category pages (sizing, compatibility, what’s‑in‑box, care, returns). Avoid burying critical specs in PDFs.
2. QA with agent‑style prompts:
   • “What’s the difference between [Model A] and [Model B]?”
   • “Do you ship to APO/FPO? How long to Chicago?”
   • “Is there a student or first‑order discount?”
   • “What’s the exchange window on sale items?”
3. Resolve contradictions: If your PDP says 30‑day returns and your policy page says 14, agents will pick one at random. Fix the source of truth.

Hours 30–42: Checkout, attribution, and risk controls

1. Pick a checkout path per channel:
   • UCP: prioritize top SKUs in GMC and ensure taxes/shipping are exact. Confirm payment methods (Google Pay today; PayPal imminent).
   • Copilot Checkout: verify enrollment and SKU eligibility with your commerce/payment partner.
   • Stripe ACP/ACS: decide whether to implement endpoints (ACP) or use hosted ACS; align with your OMS and fraud stack.
2. Attribution: Add a new order_source dimension (e.g., google_ai_mode, copilot_checkout, alexa_web, stripe_acp) in your OMS or analytics. Pass through in notes/metadata so BI can separate agentic revenue. For help designing metrics, see our metrics playbook.
3. Risk & compliance: Run a 48‑hour security pass (prompt injection, price/sku integrity, consent). Implement price‑parity and discount rules to prevent “surveillance pricing.” Use our agentic checkout security checklist.

Hours 42–48: Prove it works

1. Spin a controlled test: Choose 25–50 SKUs with clean data. Enable UCP/AI‑Mode eligibility in Google and one additional channel (Copilot or ACP/ACS).
2. Define success: Baseline PDP conversion and cart‑abandon rate; track agentic channels for add‑to‑carts, checkouts, and net margin.
3. Document edge cases: Taxes on oversized items, PO boxes, returns on bundles, gift cards, and loyalty—note anything that breaks.

Founder FAQs (this week)

“Do I need to rewrite my entire site?” No. Start by making your existing facts extractable (FAQs, tables, specs). Agents reward clarity, not fluff.

“Which should I do first: UCP, Copilot Checkout, or Stripe ACP/ACS?” You can mix paths. If you’re already strong in GMC, UCP is fastest to value. If your team prefers one integration and distribution to many agents, ACS is attractive. To control your own endpoints, build ACP.

“Will this hurt SEO?” If anything, tightening identifiers and policies helps both SEO and agents. Avoid removing indexable content; add structured answers instead.
