# What is Agent-to-agent commerce?

> Agent-to-agent commerce is a B2B transaction model in which AI agents representing a buyer and a seller exchange information — requirements, capabilities, pricing, compliance — and negotiate early deal stages autonomously, before humans meet. Humans keep final decision authority; the agents remove the repetitive discovery and qualification meetings that precede it.

In traditional B2B buying, the early stages of a deal — discovery calls, feature checklists, budget alignment, security questionnaires — consume most of the calendar time while producing information that is largely structured and repeatable. Agent-to-agent commerce moves this exchange to software: the buyer's agent carries the requirements, the vendor's agent carries an authorized subset of product, pricing, and compliance knowledge, and the two interact in minutes instead of weeks.

The model has two important properties. First, it is bounded: each side decides what its agent may disclose, so an agent conversation is closer to a structured RFP exchange than an open negotiation. Second, it is symmetrical: both sides benefit — buyers compress evaluation timelines, vendors stop spending sales capacity on unqualified discovery calls.

AgentDoor implements the information-exchange part of this model as a two-sided platform: a vendor opens a 'door' — an endpoint where other companies' agents can knock, ask questions, and check fit — so that people only take the meetings that are worth taking. It does not negotiate: agents exchange no offers or terms, and a meeting is proposed by a person on the buyer side and accepted by a person at the vendor.

## Frequently asked questions

### Do AI agents close deals without humans in agent-to-agent commerce?

No. In practice — and on AgentDoor by design — agents handle information exchange and qualification, and humans make the final decision. On AgentDoor, a vendor's door answers only from sources the vendor approved, and the vendor can name topics the door must not discuss.
