Checkout left the website. Who keeps the customer relationship?

A checkout inside a conversation can remove steps between discovering a product and buying it. It also moves part of the experience from the brand’s website to the platform that controls the conversation. Buying may feel easier; the commercial relationship shifts in pieces.

On October 5, 2026, TikTok announced two agentic commerce experiences: Buy Direct, for purchasing from a brand without leaving TikTok, and Shopping Assistant, a conversational assistant that can help with products, shipping, sizing, availability and purchase decisions. The company said it is building them with commerce and payment platforms including Shopify and Stripe. The announcement describes the product and its partners; it does not establish availability in Colombia.

Google now documents UCP checkout for eligible products in AI Mode and Gemini. Its official help page limits the experience to participating merchants and partners and eligible products in the United States, Canada and Australia. In this flow, the seller remains the merchant of record and the customer uses Google Pay. Google also requires Merchant Center preparation and approval of the integration before a merchant can go live on its AI surfaces.

Meta is building another piece. Business Agent can answer business-specific questions, recommend products from a catalog, qualify leads, let a person step in and help close sales. The agent platform can connect to business systems such as Shopify, Zendesk and Shopee. That expands an agent’s role in service and sales; the cited documentation does not describe native checkout in Messenger or Meta AI. Muse for Small Business also connects business tools, including Shopify and Stripe, but Meta presents it as a work agent that asks for approval before actions that publish, send or spend.

The label “buy in chat” hides different contracts

Platform	What its official sources describe	What a brand must confirm
TikTok	Buy Direct and Shopping Assistant bring discovery and purchase closer to the app.	Eligible countries and sellers, seller of record, payment, fees and data returned to the brand.
Google	UCP checkout in AI Mode and Gemini for eligible products and merchants; Google Pay; the seller remains merchant of record.	Approval, catalog scope, payment processing costs, customer identity and post-purchase operations.
Meta	Business Agent answers, recommends, qualifies and helps close sales through connections to business tools.	Whether a specific flow collects payment in the surface, who creates the order and which permissions the agent receives.

These options are not interchangeable. A conversation that recommends a product does not necessarily process payment. Checkout happening on Google does not remove the merchant as seller of record. An agent connected to Shopify may act on business tools, but every action remains subject to permissions and rules.

The brand has to design the whole journey

A sale has more states than “payment approved”. The catalog must reflect price and availability; the order must reach the system that prepares and ships it; the customer needs confirmation and updates; a return needs a policy and an owner. If the conversation promises what operations cannot deliver, the friction simply returns after the button.

The architecture should maintain an authoritative source for catalog, inventory and policies, then connect platforms through integrations that respect those records. Each order needs an identifier and status that can be reconciled with its channel. Changes, cancellations, retries and refunds need explicit paths. The agent should have bounded permissions: checking availability does not mean it can invent discounts or approve exceptions.

The customer relationship needs the same definition. What information reaches the brand? What consent permits it to store or use later? Can the company resolve a return without relying on the original conversation? What evidence remains if an order is disputed? Where payment happens answers none of these questions by itself.

Compare margin and continuity, not conversion alone

A new channel can raise purchase completion and still reduce the value of each customer. Measure net margin after payment, fees, promotions, delivery, support and returns. Add the share of orders with usable customer information and the percentage of buyers who return through an owned channel with permission.

Also compare what each platform provides. A marketplace can bring discovery and logistics; native checkout can remove steps; a connected agent can answer questions and support the sale. If a brand builds its own route, it takes on more acquisition, payment and fulfillment work. A useful comparison puts the cost beside the service received.

What a company in Colombia can prepare

Google currently limits its UCP checkout to eligible products and merchants in the United States, Canada and Australia. TikTok’s announcement does not specify a Colombia rollout. Meta’s tools address different use cases, and not all of them are checkout. A screenshot of a US experience is not enough to promise a local brand can activate it today.

The preparation is concrete: organize the catalog and its variants, publish consistent inventory and policies, connect the order lifecycle to the operating system, set permissions and define what customer information the company needs after purchase. This is product and systems work, not only a media decision.

Platforms may own the first conversation. The brand should decide which parts of the transaction it is willing to entrust to them and keep its own reliable record of the order, its rules and the service that follows. Without that architecture, every new checkout adds another version of the business that someone has to reconcile.
