Lemon Squeezy

What it is

Imagine a shop of record that rings up the sale, prints the receipt, and files the taxes for you — you only hand it the product. That is an "MoR (Merchant of Record)": the company that is legally the one selling to your customer, so it handles the receipt and the taxes. Lemon Squeezy is exactly that for selling digital products — software licenses, downloads, ebooks, and SaaS (Software as a Service, software you rent monthly instead of buying) subscriptions. The key difference from a raw payment processor is that Lemon Squeezy is legally the seller. It collects payment, then calculates, collects, and pays sales tax and VAT (Value Added Tax, a sales tax used in many countries) around the world on your behalf. You just connect a product and a checkout link. (This very site sells its PDF + EPUB bundle through Lemon Squeezy.)

Strengths

• Merchant of record: global sales tax and VAT are handled for you — a huge burden lifted from a solo seller.
• Fast to set up: create a product, get a hosted checkout or overlay, and start selling.
• Built for digital goods — license keys, downloads, subscriptions, and a customer portal out of the box.
• Webhooks (automatic notifications when a sale happens) and an API (Application Programming Interface, a way for programs to talk to each other) for fulfillment, plus affiliate and discount tooling.

Trade-offs

• Higher per-transaction fees than a bare processor — that premium pays for the tax handling.
• Less control over the checkout than a fully custom Stripe build.
• Geared toward digital products; not the tool for physical inventory or complex marketplaces.

Best for

Indie makers and small teams selling digital products who want payments and worldwide tax compliance solved without hiring an accountant. If you sell software, courses, ebooks, or a SaaS and don't want to register for VAT in dozens of countries, this is the easy path.

Vibe coding fit

Lemon Squeezy is a great target for vibe coding because the integration surface is small: a hosted checkout URL (Uniform Resource Locator, a web address) plus a webhook for fulfillment. A webhook is an automatic knock on your app's door: instead of your app repeatedly asking "did anyone buy?", Lemon Squeezy calls your app the moment an order is placed. Ask the agent to create a buy button that opens the checkout overlay, then a webhook handler that verifies the signature and unlocks the download or license. Because Lemon Squeezy is the merchant of record, the agent does not need to build any tax logic — tell it so, so it doesn't over-engineer.

// Verify a Lemon Squeezy webhook (server-side)
import crypto from "node:crypto";

function verify(rawBody, signature, secret) {
  const hmac = crypto.createHmac("sha256", secret);
  const digest = hmac.update(rawBody).digest("hex");
  return crypto.timingSafeEqual(Buffer.from(digest), Buffer.from(signature));
}
// On "order_created", grant access to the buyer.
