B2B to A2A

B2B to A2A is 张阔 / Zhang Kuo’s thesis in E231|从B2B到A2A:Agent新基建,如何让“一人企业”做全球生意? that business-to-business trade can evolve into agent-to-agent coordination. In this frame, a buyer’s agent, a seller’s agent, platform agents, and a user’s own master/subagents negotiate product definition, supplier fit, price, logistics, support, and follow-on operations.

The concept extends Agentic Commerce into higher-stakes physical trade. Consumer shopping agents can compare products and place orders; B2B agents must also handle specifications, certificates, factories, landed cost, payment timing, delivery risk, customs, after-sales, repeat procurement, and platform guarantees.

Key Claims

  • A2A is not only a messaging protocol; in this source it is a business-workflow claim about who performs trade tasks.
  • Buyer and seller agents need shared, auditable context because wrong prices, requirements, or logistics assumptions can destroy margin.
  • Marketplace platforms still matter because agents need trusted supplier data, transaction rails, dispute handling, logistics, and payment services.
  • Human users remain responsible for goals, acceptance criteria, and high-impact approvals, making Agent Permission Boundaries central.
  • The shift can support One-Person Company and small-team trade, but only when the agent system carries enough operational truth to substitute for missing back-office capacity.
