A major financial services company recently announced a partnership with OpenAI to advance what the industry is calling 'agentic commerce' - and the phrase is worth understanding, because it describes one of the most significant changes to how buying works since online shopping first appeared. Agentic commerce is the emerging reality in which AI agents do not merely help a customer decide what to buy - they actually complete the purchase on the customer's behalf, researching options, comparing them, and transacting. The fact that the payments industry, not just the AI industry, is now racing to build infrastructure for this tells you it is moving from concept to reality quickly. For UK businesses this raises a set of urgent and very practical questions: when it is your customer's AI agent doing the shopping, how does that agent find you, why would it choose you, and how does it actually pay you? This guide is about getting ready to be chosen - and to get paid - in a marketplace where the shopper is increasingly a machine.

What Agentic Commerce Actually Is

It helps to see agentic commerce as the natural next step in a progression. First, the internet let customers research and buy online themselves. Then AI assistants began helping customers decide - answering questions, comparing options, making recommendations. Agentic commerce is the step beyond: the AI does not stop at advising, it acts, carrying out the actual transaction on the customer's behalf. A customer might tell their AI agent what they need and let it handle the rest - finding suitable options, weighing them against the customer's preferences, and completing the purchase - with the customer perhaps only approving the final choice, or having pre-authorised the agent to buy within certain bounds. That is why the payments industry is so engaged: completing a purchase means handling money, authorisation, trust and security, so the rails that let an agent transact safely on a customer's behalf are exactly what firms like the one partnering with OpenAI are building. When those rails are in place, a meaningful share of purchasing decisions and transactions start flowing through agents rather than through humans clicking buttons - which changes what a business must do to win the sale.

The Three Questions Every UK Business Must Answer

In an agent-driven marketplace, winning a customer comes down to three questions, and they map onto the customer's agent doing its job. Can the agent find you? If your business, products and information are not discoverable and clearly understandable to AI systems, the agent shortlisting options for its customer may never consider you - you are invisible before the choice is even made. Can the agent choose you? Once found, will the agent judge you the best fit for its customer's stated needs, based on clear, accurate, comparable information about what you offer - because an agent chooses on substance and fit, not on a flashy banner. And can the agent transact with you? When the agent is ready to buy, is your purchasing process smooth, standard and machine-friendly enough that it can actually complete the transaction, or does it hit friction that sends it to an easier competitor? These three - findable, choosable, transactable - are the new requirements, and a business can be excellent in the traditional human sense and still fail all three for agents if it has not prepared.

What UK Businesses Should Do To Get Ready

Preparing for agentic commerce is not about a single technology purchase; it is about making your business discoverable, comparable and transactable to agents, deliberately. On being found: ensure your business and offerings are clearly and accurately represented in the places and formats AI systems draw on, with unambiguous information about what you sell, to whom, and why. On being chosen: make the information an agent needs to judge fit - what you offer, its real characteristics, who it suits - clear, honest and easy to compare, because agents reward substance and penalise vagueness. On being transacted with: keep your purchasing and payment processes smooth, standard and free of unnecessary friction, and stay aware of the emerging agentic-commerce and payment standards the industry is building, so you can transact through the rails agents will use. Underlying all three is a mindset shift: start treating AI agents as a real and growing category of customer - or customer's-representative - and design for them alongside your human customers, rather than assuming every buyer is a person clicking a button.

• Be findable - represent your business and products clearly and accurately in the formats AI systems use, so agents can discover you.
• Be choosable - give clear, honest, comparable information about what you offer and who it suits; agents choose on substance and fit.
• Be transactable - keep buying and payment smooth, standard and low-friction, and track the emerging agentic-commerce payment rails.
• Treat agents as a customer category - design for AI shoppers acting on customers' behalf, not just for humans clicking buttons.
• Keep trust and clarity central - accurate information and smooth, secure transactions are what earn an agent's choice and completion.

Perspective: Early, Real, And Worth Preparing For

A measured word on timing. Agentic commerce is early - most buying today still involves a human clicking buy, and that will remain true for some time, so there is no need to panic or to overhaul everything overnight. But the direction is unmistakable and the infrastructure is being built right now by the biggest names in AI and payments, which means the share of agent-mediated purchasing will grow, and the businesses that are already findable, choosable and transactable by agents when it does will capture that demand while unprepared competitors are invisible to it. This is the same pattern as every major commerce shift: the early movers who prepared while it was still emerging built an advantage over those who waited until it was unavoidable. For UK businesses, the sensible posture is exactly that - not a frantic rush, but a deliberate start on becoming ready for the moment your customers' agents come shopping, because when they do, being ready is the difference between getting chosen and getting skipped.

The Bottom Line

Agentic commerce - AI agents completing purchases on customers' behalf - is moving from concept to infrastructure fast, with major AI and payments players building the rails for it now. For UK businesses it reframes winning a customer around three questions: can the customer's agent find you, choose you, and pay you smoothly? Getting ready means making your business genuinely discoverable, comparable and transactable to agents, and starting to treat AI shoppers as the real and growing customer category they are becoming. It is early, so there is no need to panic - but the direction is clear, and the businesses preparing now will be the ones agents can find, choose and buy from when agent-driven shopping becomes mainstream, while the unprepared are simply passed over. As an AI Agency London helping businesses integrate for exactly this kind of shift, our advice is to start getting agent-ready deliberately, because in agentic commerce, being ready is being chosen.
