PayOS Alternative: Govern What Your Agents Spend
PayOS powers the merchant side of agentic commerce: payment tokens for agent checkout, plus monetization and bill payment infrastructure. Agentspay is the alternative when your problem is the buy side: controlling and recording what your own agents spend across any rail.

In short
A PayOS alternative for the buy side is a tool that governs what your agents spend, rather than enabling merchant checkout or monetization. PayOS provides network-issued payment tokens for agentic checkout plus monetization and bill payment infrastructure; it is built for merchants and platforms getting paid by agents. Agentspay is a rail-neutral, buy-side control plane: it checks every agent request against policy before money moves, pauses above a threshold for human approval, issues scoped virtual cards, and writes an immutable, agent-attributed audit trail. Choose PayOS to enable agentic checkout and monetization; choose Agentspay to govern and record what your agents spend across any rail.
Where PayOS fits
PayOS is a strong choice if you are enabling agentic checkout or monetizing an agent experience. Based in San Francisco, it provides network-issued payment tokens for agentic checkout, value-added services around payments risk and fraud, and monetization and bill payment infrastructure, along with catalog and checkout tooling. It completed a landmark agentic payment using a Mastercard Agentic Token in late 2025 and is a partner in the major card networks agentic programs. For a merchant, marketplace or platform that wants agents to be able to check out and pay at scale, PayOS is built for exactly that.
Where Agentspay fits
PayOS answers "how do agents pay merchants and how do we monetize agent activity." Agentspay answers "how do I control and record what my own agents spend." Those are different sides of agentic commerce. PayOS operates at the checkout and tokenization layer for the sell side; Agentspay is a buy-side control plane that sits in front of the issuer, cards and accounts you already run. Governance is the product: hard spend limits on amount, counterparty and velocity checked before money moves, human-in-the-loop approvals routed to Slack, email or a webhook, scoped single-use virtual cards issued by API and revoked instantly, and an immutable audit trail attributed to the agent and its owner. If your agents transact through checkout tokens, you still need something deciding whether each purchase is within budget and policy, and recording it for finance. That is the layer Agentspay owns, on any rail.
Side by side
Agentspay compared with PayOS
An honest look at how each one approaches agent payments.
| Dimension | Agentspay | PayOS |
|---|---|---|
| Side of the payment | Buy side: governs what your agents spend. | Sell side: enables agent checkout and monetization for merchants. |
| Core job | Policy, approvals and audit before money leaves. | Payment tokens, catalog and checkout, monetization and bill pay. |
| Rail neutrality | Rail-neutral and fiat-card-first across your existing issuer. | Network-issued tokens tied to the card networks agentic programs. |
| Spend policy | Hard limits on amount, counterparty and velocity, enforced before money moves. | Checkout and tokenization; buyer-side budget policy is out of scope. |
| Human approval | Threshold-based approval gates routed to Slack, email or a webhook. | Not a buyer-side approval product; it enables the checkout leg. |
| Virtual cards | Scoped, single-use, time-bound virtual cards issued by API. | Agentic payment tokens rather than developer-issued scoped cards. |
| How they fit | Governs and records the payment decision on any rail. | Can carry the checkout once a purchase is authorized. |
