The complete first-order loop

Page to payment to fulfillment signal.

01Static page

One buyer, outcome, scope, price, and deadline.

02Stripe checkout

Hosted card collection, receipts, and custom fields.

03Order monitor

Poll paid sessions by Payment Link without duplicates.

04Fulfillment

Log the order or POST it to n8n, Zapier, Make, or your endpoint.

Readable, replaceable code

The boring parts are already connected.

if (session.payment_status !== "paid") continue;
if (processed.has(session.id)) continue;

await fulfill({
  checkoutSessionId: session.id,
  customerEmail: session.customer_details?.email,
  amountTotal: session.amount_total,
  customFields: session.custom_fields,
});

processed.add(session.id);

Deliberately scoped

What it does and what it does not.

Use it for the first order

Productized consulting, audits, implementation sprints, design packages, setup services, and any offer with one fixed scope and price.

Upgrade after demand

Move polling to signed webhooks and JSON state to a database when volume or concurrent workers justify the additional system.

One payment. Keep the source.

Ship the offer, not another billing system.

The ZIP arrives automatically after checkout and includes commercial-use rights. If the first download contains nothing you can adapt for your service, request a refund within seven days.
