A fully agent-to-agent world is not here yet. Most AI assistants still help people research, compare, and narrow down their options. They are not all independently negotiating with merchant agents, approving payments, and completing purchases from start to finish.
But they are moving closer to the transaction. AI already influences what people discover, which businesses make the shortlist, and what information gets considered before someone clicks, calls, books, or buys.
So, what does that mean for merchants? Your next customer may still be human, but an AI system could increasingly shape how that customer finds you.
Here, A2A means agent-to-agent commerce: a future model in which a customer’s AI agent can discover, evaluate, and interact with a merchant’s systems or agents. For a deeper introduction, read our guide to agent-to-agent advertising and how A2A changes customer acquisition.
For a merchant, the useful question is: Is your business easy for an AI agent to understand, trust, and act on?
The road from AI discovery to A2A commerce
A2A commerce will not appear overnight. It is developing in stages.
Today, AI assistants help people discover businesses, compare products, summarize reviews, and make recommendations. The next stage brings AI closer to the transaction, helping customers build carts, check availability, initiate bookings, or move through checkout.
Further ahead, verified customer and merchant agents may exchange intent, offers, permissions, payment details, and transaction updates directly. That final stage is the A2A world.
This is still early, but merchants can already see the basics they will need: accurate data, clear offers, trusted identity, reliable action paths, and measurable outcomes. That work is useful right now, even if fully autonomous A2A commerce takes longer than expected.
1. Attention still matters. AI just adds another gatekeeper.
For years, customer acquisition was mostly about winning attention. You ran an ad, ranked for a keyword, posted on social media, and got someone to notice you. That playbook is not disappearing, but AI adds another layer between the merchant and the customer.
When someone asks an assistant to “find a family-friendly hotel near the airport” or “recommend accounting software for a small agency,” the AI may narrow hundreds of options into three or four suggestions. The customer never sees everyone who was considered.
That means merchants need more than a clever headline. They need to give AI systems enough evidence to understand the offer, who it is for, whether it is commercially relevant, and what the customer can do next.
Brand attention still gets you remembered. Machine-readable evidence helps you make the shortlist. You need both.
2. Your data becomes a machine-readable storefront
I know. Everyone says data is important. But in an A2A world, data does more than power an analytics dashboard. It may become the first version of your business that an AI agent sees.
An agent cannot reliably recommend a product if the price is missing, availability is unclear, or the description contradicts another listing. It does not want to guess whether you ship to Singapore. It wants a clear answer.
That includes basics such as product descriptions, pricing, availability, delivery terms, eligibility, and a clear path to purchase or enquire.
This information should be consistent across your website, product feeds, business profiles, marketplaces, and partner platforms.
Clean data is not glamorous. But that boring backend work? It is becoming part of customer acquisition.
3. Reputation becomes easier for agents to evaluate
Reviews already influence customers. In an agent-led journey, reputation may be evaluated before the customer even sees the available options. There is no single universal AI reputation score today, but there are plenty of signals for an agent to work with.
AI systems can combine signals from reviews, business listings, policies, third-party mentions, support information, and the consistency of a merchant’s public data.
A merchant with a beautiful website but conflicting details may be harder to recommend than a less polished competitor whose identity, pricing, policies, and reputation are easier to verify.
Standards are also emerging for machine-verifiable trust. The W3C Verifiable Credentials Data Model, for example, provides a way to express claims about identity or eligibility in a format that software can verify and detect tampering in.
That does not automatically make every claim trustworthy. An agent still needs to consider who issued the information, whether the source is credible, and whether the claim is relevant to the customer’s request.
For a merchant, this comes down to how clearly that evidence is published and whether it comes from sources worth trusting. Business identity, certifications, policies, and third-party proof all become more useful when a machine can verify where they came from.
Make trust easy to check. Keep business details consistent, respond to reviews, publish policies in plain language, make support paths visible, and correct outdated listings. Reputation is no longer just what people say about you. It is also what machines can confirm.
4. Search is evolving into delegated discovery
Search is not dead. People still use Google, browse websites, and compare options manually. But some of that work is being delegated.
Instead of searching for “best wireless earbuds under $100,” a customer might ask an AI to find earbuds under $100 that stay secure while running, have good call quality, and can arrive before Friday.
The AI interprets the customer’s constraints, compares the options, and filters the results. The customer does less of that comparison work themselves.
In traditional search, the customer opens pages and weighs the options. In agent-assisted discovery, the customer describes a goal and receives a shortlist. In a future A2A journey, the customer’s agent may communicate intent directly to merchant systems, evaluate the response, and proceed with permission.
SEO remains important because AI systems still need accessible, understandable sources. But keywords alone are not enough. A merchant also needs clear product information, evidence that the business can be trusted, and a reliable path to buy, book, or enquire.
5. Feeds, APIs, and protocols become distribution infrastructure
Your website remains important. It explains your brand, builds trust, and gives customers a place to learn and act. But it may no longer be the only place where the buying journey happens.
Product feeds already distribute merchant information across search engines, marketplaces, comparison services, and advertising platforms. APIs make it possible to check inventory, calculate prices, start bookings, or create orders in real time. New commerce protocols are attempting to make those interactions more consistent.
Google’s Universal Commerce Protocol is one example. It is designed to connect consumer surfaces, merchant systems, and payment providers across discovery, checkout, and order management.
UCP supports different ways for systems to communicate, including APIs, A2A, and MCP. Merchants do not need to memorize those protocol names. What matters is that software is getting better at coordinating product discovery, checkout, and what happens after an order.
This is already showing up in commerce platforms. Shopify says its Agentic Storefronts can make merchant catalogs available across AI shopping channels, including ChatGPT, Microsoft Copilot, Google AI Mode, and Gemini.
Most merchants can leave the protocol work to platforms for now. Their job is to keep the underlying offer accurate and usable wherever it appears. Product data may increasingly travel to the customer’s AI through feeds, structured data, integrations, and commerce platforms.
Your next acquisition channel may look less like an ad placement and more like a system that can understand what you sell and route qualified intent toward it.
6. Branding is not dead. It shapes the preferences people give their agents.
If AI agents help make decisions, does branding stop mattering? No. Humans still define the preferences.
A customer may tell an agent:
- Only recommend brands I trust.
- Avoid companies with difficult returns.
- Prioritize sustainable businesses.
Those instructions are influenced by brand familiarity, past experiences, reputation, and emotion. A strong brand may enter the decision before an AI starts comparing specifications.
Branding therefore moves in two directions. It still helps people remember and prefer you, but it also influences the rules people give their agents. The data may get a merchant considered. The brand may help it get chosen.
7. Transparency, permission, and control become transaction requirements
As AI gets closer to purchasing, trust becomes more than a marketing message. Merchants will need to know whether an agent is legitimate, whether it has customer permission, what it is authorized to do, and how refunds or disputes should be handled.
These questions become more important as software moves from recommending a product to initiating a transaction. The goal should not be to accept every automated request, but to create clear rules around what an agent can see, what it can do, and what requires human approval.
Agent-led commerce will depend on recognizable identity, secure payment controls, transparent policies, traceable actions, and clear customer consent.
Once software can spend a customer’s money, clear rules and visible consent stop being nice-to-have trust signals. They become part of how the transaction works.
The A2A readiness checklist for merchants
| Signal | What merchants should publish | Why agents care |
|---|---|---|
| Offer fit | Products, services, audience, locations, eligibility, and use cases | Helps match the business to a specific customer request |
| Commercial clarity | Pricing, availability, delivery, promotions, and policies | Reduces uncertainty before a recommendation |
| Trust | Reviews, guarantees, identity, third-party references, and support details | Provides evidence that the business is safe to suggest |
| Actionability and permission | Checkout, booking, quote, demo, or lead paths with clear customer controls | Makes it possible to move from discovery to an authorized outcome |
| Measurement | Referral source, assisted conversion, order, and revenue data | Shows whether AI-assisted discovery produces real business results |
You do not need to solve everything at once. Start by making your existing offer easier to understand and easier to complete.
Knowing what needs attention is one thing. Working out where to start is harder.

Final thought
We are not living in a fully A2A world yet. Customers still search. Websites still matter. Brands still influence decisions. Human approval remains essential. But AI is becoming a more active participant in discovery, comparison, and commerce.
No one can say exactly when autonomous agents will transact at scale. Merchants can still prepare for the more immediate shift: more buying decisions will be assisted, filtered, or initiated by software.
The businesses that publish clear information, build verifiable trust, maintain reliable action paths, and measure real outcomes will be better prepared—whether full A2A commerce arrives quickly or takes years.
A2A may be where commerce is headed. For now, the useful work is making your business easier to understand.
FAQ
How will AI agents change the way merchants acquire customers?
AI agents will shift acquisition from buying attention to being selected by assistants. Merchants will need offers and business data that agents can understand, compare, and recommend. Fit, trust, availability, pricing clarity, and measurable next steps will matter more.
What merchant data do AI agents need to recommend a business?
Agents need clear and current details: products or services, pricing, availability, location, delivery options, policies, reviews, eligibility, promotions, and next steps. The more structured and consistent this data is, the easier it is to match a merchant to buyer intent.
Why are traditional ads less reliable in agent-led commerce?
Traditional ads rely on impressions, clicks, and persuasion. In agent-led commerce, the assistant may narrow options before the customer sees them. That makes pure exposure less reliable. Agents are more likely to prioritize relevance, verified details, value, availability and trust.
How should merchants prepare for agent-to-agent customer acquisition?
Merchants should make offers easy for AI systems to read and act on. Start with structured product or service details, clear pricing, accurate profiles, third-party credibility, clean conversion paths, and analytics that connect AI-influenced discovery to purchases, leads, or bookings.
