Payments for agent-built SaaS

Merchant of record is only one part of AI app billing.

A merchant of record can help with checkout, tax, refunds, and disputes. Agent-built SaaS still needs the product layer: login, entitlements, usage metering, per-user balances, and a safe way to charge for AI calls.

MoR

Useful for tax and seller-of-record work

Paddle and Lemon Squeezy are common choices for digital products because they can act as merchant of record. Stripe offers checkout and payment infrastructure, and some Stripe products cover managed payment responsibilities for eligible businesses.

Gap

AI apps need metered entitlements

The hard part is not just taking a card. It is deciding who pays for each model call, refunding failed jobs, preventing runaway spend, and opening access after payment.

SettleMesh

Agent-built apps need a launch layer

SettleMesh packages deploy, auth, database, usage billing, and service calls into one path a coding agent can operate after it writes the app.

Questions to answer before choosing a payment stack
1. Are you selling SaaS access, API credits, files, services, or one-off downloads?
2. Do users trigger paid AI/model/search/media calls?
3. Do you need subscriptions, prepaid credits, or per-action charges?
4. Who handles VAT, GST, sales tax, refunds, and disputes?
5. What happens when a paid background job fails?
6. How does payment unlock app access, API quota, or license rights?

FAQ

What is a merchant of record?

A merchant of record is the entity responsible for selling to the customer and handling parts of the payment, tax, compliance, refund, and dispute workflow. SaaS builders compare MoR providers when they do not want to manage those obligations directly.

FAQ

Do agent-built apps always need a merchant of record?

No. A simple app may only need a payment link or checkout. An AI app with usage-based compute, credits, user wallets, refunds on failed jobs, and paid API calls often needs an additional metering and entitlement layer even when a MoR handles checkout.

FAQ

Where does SettleMesh fit?

SettleMesh focuses on agent-built apps that need deploy, login, database, metered usage, and end-user payments together. It can sit beside payment providers by turning prepaid top-ups into app-level usage billing.
