Have payments drafted for you. Let agents prepare payments and transfers. You review and approve with a quick tap in the Mercury app.

Organize your transactions. Agents can find and categorize transactions, add notes, and create new categories on request. No approval needed if no money is moving.

Oversight built into the account

With Mercury Agent Controls, you can see who connected each agent, what it’s allowed to do, what it’s done, and disconnect agents in seconds.

You decide the rules. Mercury enforces them.

When you connect an agent, you decide what it can do. Mercury checks every request against the access granted and the associated user’s permissions, then allows it, routes it for approval, or blocks it.

Keep receipts on agent actions

See what each agent did and which Mercury user it acted for, giving you a clear record of agent activity across your account.

Money never moves without your approval

Nothing leaves your account until you approve it with a tap in the Mercury app.
