About OpenMerchant
OpenMerchant is software that lets AI agents buy and pay on a business’s behalf, within rules a person sets.

Mission
AI agents are about to do most of the buying and paying a business does. OpenMerchant exists so they can do it safely.
Every purchase and every payment moves on rules a person set, with checks a person can read, and the agent never holds the authority on its own. Every product here is a version of that idea.
What is live today

- Pay vendors
The vendor invoices that arrive in your inbox, handled on rules you set and held for you when anything is new.
- For developers
The same tools for your own agent, over REST or an MCP server, under the same rules.
