PayPal + Supabase licensing kit

Charge for your code the same day you write it.

Ship & Charge wires PayPal checkout, signature-verified webhooks and automatic license keys into any app. Clone it, set five environment variables, sell. No subscription, no revenue share, no vendor lock.

Battle-tested. Two live products run on this exact stack.
Honest demo. The buy button on this page runs on Ship & Charge itself.

Three steps, one afternoon

Connect

Create a PayPal REST app and a Supabase project. Paste five keys into the config. Sandbox mode lets you test-buy for free first.

Deploy

Run the schema, deploy two edge functions, point your buy button at one URL. The guide walks every click.

Get paid

Buyer pays, PayPal calls your webhook, signature gets verified, the license key appears on their success page and in your dashboard. Automatically.

What’s in the box

Checkout function

Creates a PayPal order and hands back the approve link. Product name, price and return URLs are environment variables.

Webhook handler

Verifies every event against PayPal’s signature API before trusting it. Duplicate deliveries are ignored by design.

License engine

Readable keys (XXXX-XXXX-XXXX-XXXX), stored in Postgres with row-level security. Anon visitors can read nothing.

Admin dashboard

Single-file dashboard: stats, search, revoke and restore. Ships with demo data so you can preview before connecting.

Sold by the stack it ships

Every claim on this page is checkable. When you click Buy with PayPal, you trigger the same checkout function you’ll download, verified by the same webhook handler, issuing the same license format you’ll own. If it works on us, it works for you.

Questions

Do I need a business PayPal account?

A personal account works for testing in sandbox. For live sales, PayPal requires a business account — it’s free to create.

Subscriptions or one-time only?

One-time payments today. The webhook pattern extends to subscription events; the guide marks the exact place to add them.

What do I need to run it?

A free Supabase project and a PayPal account. Everything else — schema, functions, dashboard — is in the download.

Which stack is it written in?

TypeScript edge functions (Deno), plain SQL, and a dependency-free single-file dashboard. No framework to learn.

Refunds?

30 days, processed through PayPal, no questions asked. The admin panel has a revoke button for exactly this.

One afternoon. One payment stack. Yours.
