Consent, authorization, and auditability built in Retail is entering a new interface era: customers will increasingly describe what they want, and an AI agent will find, compare, add to cart, and complete checkout often without the customer ever visiting a retailer’s site or tapping a traditional “Buy” button.
Industry analysts are already calling this shift “zero-click buying” purchases completed without leaving the conversational experience. And in January 2026, major platforms publicly accelerated this direction: Google announced expanded in-chat shopping and checkout capabilities for Gemini through partnerships with large retailers and commerce platforms, unveiled around NRF 2026.
For retailers and brands, the implications are structural: the “customer journey” is being delegated to agents, and the winners will be those who become agent-ready with trusted product data, real-time inventory and pricing, clean fulfillment signals, and secure commerce APIs that agents can transact against.
At ACI Infotech, we view “zero-click retail” as a data-and-architecture challenge before it becomes a marketing challenge.
What is “zero-click retail” in practical terms?
Zero-click retail is not a single feature. It is a new journey pattern:
- Intent: “I need running shoes for flat feet under $120, delivered by Friday.”
- Delegation: The agent queries multiple catalogs, reads reviews/specs, checks size availability, and evaluates delivery feasibility.
- Decisioning: The agent proposes options, explains tradeoffs, and optimizes to the shopper’s constraints.
- Transaction: Checkout occurs inside the agent interface often through standardized protocols and merchant integrations rather than the retailer’s web funnel.
- Post-purchase: The agent handles changes, returns, warranty, substitutions, and replenishment.
This is already being productized. OpenAI and Stripe have described an open Agentic Commerce Protocol intended to enable programmatic commerce flows between AI agents and businesses, including “Instant Checkout” experiences.
Why 2026 is the inflection point
Two forces are converging:
1) Platforms are embedding checkout inside AI
Google’s Gemini shopping partnerships and in-chat checkout push reduce the need for users to jump out to a retailer site. Google has also described “agentic checkout” experiences and shopping workflows in its product updates.
2) Consumers are adopting AI as a shopping layer
A recent IBM Institute for Business Value study with NRF reported meaningful consumer usage of AI during buying journeys (nearly half in their survey).
In parallel, large retailers and marketplaces are rolling out their own AI shopping assistants. Amazon, for example, has positioned Rufus as an AI shopping assistant designed to make shopping faster with recommendations and answers, with strong usage signals described by Amazon/AWS.
The customer journey is being rewritten (from funnel to delegation)
Traditional digital commerce is a funnel you control: traffic → product page → cart → checkout.
Agentic commerce shifts control to an agent that optimizes for the shopper’s goal—often across multiple merchants:
- Discovery is no longer “search keywords.” It’s “constraints and preferences.”
- Merchandising is no longer “onsite placement.” It’s “how well your data and offers satisfy an agent’s ranking logic.”
- Conversion is no longer “checkout UX.” It’s “transaction reliability, trust, and fulfillment certainty.”
- Loyalty becomes “the agent’s preference model,” not just the customer’s memory of your site.
BCG has warned that, without intervention, retailers risk being reduced to background utilities in agent-controlled marketplaces.
What “agent-ready retail” actually requires
If agents become the primary interface, your differentiator becomes the quality, reliability, and governance of what the agent can “see” and “do” with your systems.
1) Product data that agents can trust
Agents will not tolerate messy catalogs.
Minimum requirements:
- Clean, complete product attributes (size, materials, compatibility, regulatory claims, warranty)
- Normalized taxonomy across channels
- High-confidence review and Q&A summarization inputs (with provenance)
- Rich availability signals at SKU-location level
Key shift: SEO becomes Structured Product Truth.
2) Real-time inventory, pricing, and promise dates
In zero-click experiences, “in stock” is not enough. Agents optimize against certainty:
- On-hand and available-to-promise inventory
- Delivery-date confidence windows
- Substitution rules and backorder logic
- Dynamic pricing and promotion eligibility rules
If your promise dates are unreliable, agents will route demand elsewhere.
3) An “agent transaction layer” (secure APIs + protocols)
Agents will transact via standardized patterns and well-governed merchant endpoints. OpenAI and Stripe’s work on agentic commerce standards reflects this direction.
Retailers should plan for:
- Cart and checkout APIs built for delegation (idempotency, retries, strong reconciliation)
- Policy-based guardrails (age restrictions, controlled products, geo restrictions, fraud throttles)
- Explicit customer consent and confirmation checkpoints
- Audit logs that prove who authorized what
4) Identity, consent, and privacy by design
When an agent shops “for” a user:
- Who is the legal purchaser of record?
- How is consent captured and stored?
- What customer data is the agent allowed to access and for what purpose?
Retailers must treat consent as a first-class object, not a footer checkbox.
5) Post-purchase operations that agents can manage
Returns, exchanges, warranty claims, subscription changes, and delivery exceptions will increasingly be handled by agents. If those workflows are not API-accessible and policy-driven, you’ll lose margin to manual service costs.
New KPIs for the zero-click era
As direct traffic becomes less predictive, retailers should add measures such as:
- Agent Share of Consideration: how often agents include your products in top results
- Agent Conversion Rate: checkouts completed via agent channels
- Offer Reliability Score: cancellations, substitutions, late deliveries, inventory mismatches
- Catalog Trust Score: attribute completeness, spec accuracy, returns due to “not as described”
- Margin Leakage: promo stacking, unintended discounts, agent-driven price matching dynamics
The retailer that wins is the one with the most machine-readable trust.
Risks retailers must address now
Zero-click retail introduces real failure modes:
- Brand erosion: agents may flatten differentiation into price/availability unless you provide richer value signals.
- Hallucinated claims: if an agent states something incorrect about your product, you still bear customer dissatisfaction risk.
- Fraud and abuse: delegated checkout can increase attack surface if identity and authorization are weak.
- Regulatory exposure: data use, consent, and automated decisioning need defensible controls.
The answer is not “block agents.” The answer is governed enablement.
ACI Infotech perspective: the winning architecture pattern for 2026
Retailers should treat agentic commerce readiness as a modernization program with three deliverables:
- Agent-Ready Data Foundation
a. Unified product + inventory + customer data (with governance)
b. Real-time pipelines and observability - Secure Commerce API Layer
a .Delegation-ready checkout, returns, and service APIs
b .Consent, authorization, and auditability built in - Decision Intelligence & Guardrails
a .Offer optimization and margin control
b .Policy controls for restricted items, jurisdictions, and fraud signals
ACI Infotech helps retailers implement this across cloud modernization, data engineering, applied AI/ML, and cybersecurity so agentic channels drive growth without creating new risk.
Closing: from “digital experience” to “digital delegation”
In 2026, the question will not be whether shopping agents exist they will. The question is whether your retail stack is prepared for delegated journeys where the “shopper” is an AI agent acting under customer intent.
If you want to compete in zero-click retail, start with one practical move: make your catalog, availability, and checkout machine-trustworthy and prove it with observability and audit trails.
FAQs
It means your site/app may no longer be the primary conversion surface for a growing share of demand. AI agents can handle discovery, comparison, and even checkout within their own interface. Your digital properties still matter for brand, content, and direct relationships but you also need an “agent-ready” commerce layer (trusted data + secure APIs) so agents can transact reliably.
Agents optimize against machine-readable signals: product attribute completeness, spec accuracy, availability certainty, delivery promise reliability, return policies, ratings/reviews quality, and price/value. Retailers will need to invest in structured product truth, clean taxonomy, and reliable inventory/promise-date signals similar to SEO discipline, but optimized for agent ranking logic rather than human clicks.
At minimum: real-time inventory and pricing, idempotent cart/checkout APIs (safe retries), strong reconciliation, fraud controls, and an authorization/consent layer that clearly captures customer intent. Retailers should also implement audit logging so they can prove what was authorized, what the agent did, and why especially for disputes and chargebacks.
Common risks include hallucinated product claims, unintended promo stacking, fraud via delegated checkout, and privacy/consent issues. Mitigations include: governed product data (approved claims only), policy-based promotion rules, throttling and step-up authentication for high-risk orders, explicit consent checkpoints, and comprehensive transaction logs with monitoring for anomalies.
Add KPIs that reflect agent-mediated journeys, such as: Agent Share of Consideration, agent conversion rate, offer reliability (cancellations/late deliveries), catalog trust (returns due to “not as described”), and margin leakage from discount/promo interactions. These metrics help teams optimize for reliability and profitability not just traffic and click-through.
