Confident agent. Imaginary API.
Your agent invents an endpoint. You spend the afternoon untangling payment code that never worked.
YOUR NEXT COMMIT: REVENUE
From shipped
to paid.
You vibe-coded the app. Now let your coding agent add payments, webhooks, paywalls and a launch checklist that actually work, in an afternoon.
Polar or Stripe, your choice · Works with Codex, Claude Code and Cursor

SHIPPED → PAIDBuilt for the real world
Less payment plumbing. More building.SKILLS + COMMANDS + STARTER
SHIPPING IS ONLY HALF THE JOB
The demo works. Does the money part?
Payment code is where “looks right” gets expensive.
A webhook isn’t just a POST.
Events silently fail. Signatures go unchecked. One spoofed request becomes a very real problem.
Paid doesn’t always mean access.
Customers pay and stay locked out. Or cancel and keep Pro. Your entitlements need to follow the money.
THE TOOLKIT
Everything between “it works” and “it sells”.
Give your agent the instructions. Give your app a business model.

- Read the raw body before verifying signatures.
- example.com emails can get rejected with 422.
- Stale webhooks can restore revoked access.
- The wrong product can accidentally grant Pro.
- The SDK needs Node 22.
- The portal returns 422 for users who never paid.

A FEW MORE THINGS
Good questions.
Here’s what to know before you ship.
Why not just use free skills?
There’s a free lite pack with 3 skills. The full pack goes further: entitlements, credits, license keys, full Stripe support, a launch audit, plus a tested starter and scripts. Every gotcha comes from building it for real.
What if I cancel?
Nothing to cancel. ShipToPaid is a one-time purchase with lifetime updates.
What’s the refund policy?
Try it for 14 days. If it’s not for you, ask for a full refund. No questions asked.
Which stacks does it work with?
The starter and primary examples use Next.js App Router. The skills also include notes for adapting the workflows to other stacks.
Polar or Stripe?
Your choice: both are first-class, with their own checkout, webhook and portal skills, and both are live-tested in the starter. Polar is a merchant of record, so it handles sales tax for you. Stripe fits if you already have an account; you handle tax yourself, e.g. with Stripe Tax.
What about iOS?
iOS support is planned for later. Buyers will receive it as an update when it’s available. The pack is web-first today.
How do I get it?
After purchasing via Polar, you’ll get access to the private GitHub repo with the skills, slash commands, starter and scripts.
