Cascade will happily refactor your whole repo — but it can't wait in a merchant-approval queue for you. Now it doesn't have to: it can open the account itself.

The problems Windsurf builders actually hit

You’ve seen these. So have we.

✗ Hours of PSP wiring — even with an agent

Keys, endpoints, signatures, test flows: the 2026 guides still budget 1–2 careful hours.

source: integration guide →

with paas.build: Three lines with @paasbuild/react; the agent does the rest.

✗ The activation wall

Scaffold in minutes, then wait on merchant activation — the queue doesn’t care how fast your agent is.

source: SaaS-building guide →

with paas.build: The account is created in-session: capped, real, yours.

✗ Webhook plumbing before revenue

Signature verification and endpoint juggling before the first sale.

source: builder guide →

with paas.build: First payment with zero webhook plumbing.

Three steps

From prompt to first payment

1. Hand Cascade the task

Paste the prompt below — our docs are agents-first, one call from zero to checkout.

2. Account in the same session

go-live returns sandbox + production vendors with real tokens — capped, live, no review week.

3. First £1, then subscriptions

Take a £1 test payment, watch it land in your merchant portal, then let Cascade wire Free/Pro/Max.
