Why this matters right now

Agent‑led shopping isn’t a future bet—it’s live. Buyers are asking assistants to find, compare, and buy. That means your catalog, pricing, fulfillment promises, and risk rules must be machine-readable, permissioned, and verifiable. If you’ve been following our coverage, you’ve already seen the playbook foundations:

• AI Checkout Goes Mainstream — Your 7‑Day Plan
• The Payments Play in Agentic Checkout
• How to Measure Agentic Checkout ROI
• Agentic Checkout Security Checklist

This article upgrades those frameworks into a compact 10‑day sprint for Shopify, WooCommerce, and headless stacks.

Who should move first

• DTC and marketplace brands with >$50k/month GMV
• Stores with multi‑variant catalogs (size/color) or MAP‑sensitive pricing
• Teams already running performance channels (search, social, affiliates) and needing clean attribution

The 10‑Day Founder Plan

Day 1–2: Ship an agent‑ready product feed

• Normalize SKU/variant IDs and ensure canonical URLs with rel=canonical.
• Expose structured data (price, availability, condition, shipping, return window) and include image alt text.
• Map attributes: size, color, materials, battery life, warranty. Agents need deterministic comparisons.
• Add a Return & Warranty field and a Last Updated timestamp per item.
• Keep a public Q&A block for top objections; it doubles as agent fodder. See our 48‑hour feed guide: Ship an Agent‑Ready Product Feed.

Day 3: Payments triage that won’t nuke conversion

• Prioritize Google Pay and PayPal where your audience already uses them; enable Stripe accelerated checkout or similar tokens as a fallback.
• Turn on SCA/3DS flex rules for high‑risk baskets; keep friction low for repeat buyers.
• Pre‑approve agent‑initiated intents within risk thresholds (value, geography, velocity).
• Deep link to a single, minimal step checkout page. Reference our payments prioritization guide: What to Enable First.

Day 4: Consent, security, and price integrity

• Lock content with a Content Security Policy and sanitize user‑provided inputs to reduce prompt‑injection vectors.
• Sign price & availability payloads server‑side; reject stale cart resumes.
• Gate sensitive actions (address changes, payment method swaps) behind step‑up authentication.
• Run our 48‑hour safety sweep: Security Checklist.

Day 5: End‑to‑end QA on agent surfaces

• Test discovery → comparison → cart → pay across mobile and desktop.
• Validate variant selection accuracy and shipping ETA consistency.
• Simulate out‑of‑stock, backorder, and preorder flows.
• Ensure returns link and support handoff are visible at checkout.

Day 6: Measurement you trust (not vibes)

• Tag agent traffic with UTMs (source/medium/campaign=agent_channel).
• Send server‑side events for view, add_to_cart, begin_checkout, purchase; dedupe with client IDs.
• Configure postbacks from your PSP and reconcile with your CRM/CDP.
• Run a geo or time‑split incrementality test for 7–14 days. Our full attribution playbook: Measure Agentic Checkout ROI.

Day 7: Business answers and AASO hygiene

• Publish a Concise Business Answers page: shipping, taxes, warranty, returns, sustainability, financing.
• Create a product comparison table for your top 5 SKUs vs. nearest substitutes.
• Refresh FAQ schema with the top 20 buyer questions. See: AASO in 2026.

Day 8: Support automation readiness

• Update macros for agent‑origin orders (identify by UTM or order tag).
• Expose self‑serve order tracking and returns initiation links.
• Route anomalies (address mismatch, duplicate charge) to a human‑in‑the‑loop queue within 2 hours.

Day 9: Offers and merchandising tuned for agents

• Create agent‑exclusive promos (e.g., AGENT10) to measure lift cleanly.
• Bundle accessories into assistant‑friendly kits with clear value deltas.
• Publish transparent shipping thresholds to reduce cart churn.

Day 10: Experimentation & guardrails

• AB test one variable at a time: payment button order, free‑ship threshold, returns copy.
• Set max discount, max quantity, and geo guardrails for agent‑initiated carts.
• Document an escalation runbook for fraud spikes or feed bugs.

The KPI scorecard (watch daily)

• Agent‑Attributed Revenue (AAR): revenue where source contains an agent channel tag.
• Checkout Success Rate: agent sessions reaching pay success ÷ agent sessions reaching checkout.
• Variant Accuracy: returns due to wrong variant ÷ agent orders (<1% goal).
• Latency to Pay: median time from cart create to payment success (<90s goal).
• Chargeback Rate: keep <0.6% rolling 60 days; auto‑tune risk rules accordingly.

Two quick examples

Example A: Apparel (Shopify)

We normalized variants (size/color), added material & care attributes, and exposed returns windows by country. Result: agent surfaces stopped defaulting to the wrong colorway, checkout success rose 8% with Google Pay first.

Example B: Electronics (Headless)

We signed price/availability payloads and added warranty term fields. Agents began recommending the higher‑margin bundle; chargebacks held flat thanks to flexible 3DS.

Common pitfalls (and fixes)

• Stale inventory → add freshness timestamps and soft‑reserve on add_to_cart.
• Promo mismatch → expose active promo rules in your feed and validate at cart.
• Inconsistent shipping → compute ETA server‑side and display the same text across web and agent flows.
• Attribution fights → decide the source‑of‑truth hierarchy now (analytics vs. PSP vs. CDP) and stick to it.

What to do next (today)

1. Declare an owner for feed integrity and an owner for payments & risk.
2. Ship Day 1–3 tasks in a 72‑hour sprint; measure with Day 6 instrumentation.
3. Set guardrails and QA with a test card + live $1 offer before scaling.
