Agentic Payments: AI Agent Payment Controls, Vendor Comparisons and Implementation Guides

Agentic payments are payments an AI agent initiates on your behalf, without a human clicking buy. The hard part is not letting an agent pay. It is deciding, before the money moves, how much it may spend, who it may pay, and when a person has to sign off.

Start here

If you are evaluating rather than reading, go straight to the decision. Set a ceiling an agent cannot cross with agent spend controls, bind an agent to one merchant with a scoped virtual card, and hold anything large for a named human with approval thresholds. To see how the platforms you already pay for handle this, we measured the published schemas behind Gemini Enterprise, Microsoft Agent 365, AWS AgentCore, Salesforce Agentforce and ServiceNow AI Control Tower. To compare vendors head to head, start with AI agent payment platforms or browse every alternatives comparison.
