Use case
SaaS Buying Agent - Subscribe Without Renewal Surprises
An agent that trials, buys, and renews SaaS can quietly stack up subscriptions. Give each tool a scoped, revocable card and a spend cap you control.
In short
A SaaS buying agent signs up for, trials, and renews software tools on your behalf. Agentspay issues a merchant-locked virtual card per vendor with a hard cap, so a forgotten trial cannot silently convert into an expensive plan. You can revoke any card instantly to cancel a renewal, and every subscription charge is attributed to the agent, the owner, and the policy that allowed it.
The challenge
A buying agent can leave a trail of auto-renewing subscriptions that nobody remembers approving until the charges hit the statement.
How Agentspay handles it
Agentspay issues a scoped virtual card per SaaS vendor with a per-vendor cap, so each subscription is isolated and capped. When you want to cancel, you revoke the card and the renewal is declined, no support ticket required. Spend above your threshold pauses for approval, and the audit trail shows every active subscription and what it costs.

The control surfaces
The controls behind it
The surfaces this use case leans on, each enforced before any money moves.
Virtual cards
Virtual cards
Virtual cards for AI agents are programmatically issued card credentials that are scoped to a single merchant, amount, and time window. The agent uses a tokenized, masked reference and never sees a raw card number, which keeps you out of PCI scope. You issue and revoke them through a virtual cards API.

Spend controls
AI agent spend controls are rules that limit what an agent can buy: per-transaction, daily, and total caps, merchant and category allowlists, and velocity limits. Agentspay evaluates them at the API boundary, so a hallucinating or compromised agent is declined before it can overspend, not flagged after.
Learn moreAudit trail
Audit trail
An audit trail for AI agent spending is an immutable, append-only record of every payment an agent made. Each row links the spend to the intent that triggered it, the agent that requested it, the human who owns the agent, the policy verdict, and the approver. It gives you cost attribution, reconciliation, and a record you can defend.
Learn moreHuman approvals
Human approvals
Human in the loop agent payments means an agent's transaction pauses for human sign-off when it crosses a threshold you set. The agent waits, the request is sent to Slack, email, or a webhook, and nothing settles until a person approves or denies. The decision and approver are recorded in the audit trail.

API billing agents
When an agent pays per API call, a loop is a bill. Cap the spend, throttle the velocity, and attribute every dollar to the provider it paid.

A travel agent that books flights, hotels, and cars touches high-value, irreversible charges. Cap the trip, lock the suppliers, and require sign-off on the expensive legs.
ExploreAd spend agents
Ad spend agents
An agent that manages ad budgets can scale spend faster than a human can watch. Put daily and total caps on it, one card per platform, and sign-off on budget jumps.
ExploreCloud cost agents
Cloud cost agents
An agent that provisions compute can spin up expensive resources in seconds. Cap the spend, throttle how fast it grows, and require sign-off before it scales up.
ExploreBill pay agents
Bill pay agents
An agent that pays recurring bills saves your team a chore, but only if it cannot pay the wrong invoice, the wrong amount, or the same bill twice. Give it a capped wallet, a vendor allowlist, and sign-off on anything unusual.
ExploreRefund agents
Refund agents
A support agent that can refund a customer resolves tickets faster, but an agent with an open refund button is a liability. Cap each refund, cap the day, and make anything large wait for a person.
