Let AI Buy for You: Meet the Agentic Commerce Protocol (ACP) and Turn Chats into Sales

Why this matters now

Imagine saying: “Find me a sleek carry-on under $100.” Your AI assistant proposes the best options, confirms shipping, applies a discount, and completes payment—without leaving the chat. That’s the promise of the Agentic Commerce Protocol (ACP), an open standard that lets AI agents, merchants, and PSPs coordinate safe, instant checkout.

ACP in one page

• A unified purchase language: From cart initiation and quoting (taxes, shipping) to confirmation and secure payment token handoff to your PSP.
• Open & flexible: Apache-2.0; implement via REST or as an MCP server—no overhaul of your stack.
• Merchant-first control: You remain Merchant of Record—own payments, fulfillment, policies, and the customer relationship.

Why your brand should care

• Higher conversion, less friction: Fewer redirects and form fills → more completed purchases.
• New conversational channel: Be present where intent is born—inside the chat.
• First-mover edge: Agent-ready catalogs gain early placement and trust.

How ACP works (clean, reliable flow)

1. Initiate: Agent sends an ACP request with items, address, and prefs.
2. Quote: Merchant returns canonical checkout state (lines, taxes, shipping, total) + next actions.
3. Confirm: Agent gathers user approvals (address, shipping, promos).
4. Authorize & Pay: Agent passes a PSP-compatible payment token for auth/capture—no screen-scraping.
5. Fulfill & Notify: Merchant confirms order & tracking; agent updates the user in-thread.

Quick-start playbook (marketing + engineering)

• Harden product data: titles, images, prices, stock, and shipping rules must be consistent for agent display.
• Pick integration mode: REST first; add MCP tools if your agent platform supports it.
• PSP readiness: Start with a provider supporting ACP shared tokens (Stripe first implementation).
• Risk & policy: Allow/deny per agent/SKU/region; require SCA/3DS if needed; log signed agent requests.
• Measure & optimize: Track quote→pay conversion, declines by reason, and fulfillment SLAs.

Marketing touches that move the needle

• Clear CTA: “Own a sales channel inside the chat—enable ACP with Bayantrix.”
• Value promise: “Less friction, more conversion.”
• Urgency: “Be first to show up when buyers ask.”
