Conversion tracking for Lemon Squeezy
Lemon Squeezy is a merchant of record aimed at small digital businesses, which means it carries the same structural constraints as Paddle with a smaller team behind the store. Checkout is hosted or an overlay, the transaction record lives in Lemon Squeezy rather than your database, and tax is handled for you and included in the price the customer sees. For most stores on it the honest first question is whether any of this is worth doing at all — and for a genuine share of them, it is not.

Lemon Squeezy tracking · what breaks
What goes wrong on Lemon Squeezy
- 01
Hosted checkout on another domain
Your first-party cookies do not travel there, so the identifier has to be passed deliberately.
- 02
The order record living outside your database
Lemon Squeezy is the merchant, so it holds the authoritative record.
- 03
License and subscription renewals with no browser
Digital products renew on a schedule like any subscription.
- 04
Tax-inclusive pricing
What the customer paid and what you receive differ, and comparing them produces a gap that looks like a bug.
Lemon Squeezy tracking · the fix
What changes — Lemon Squeezy tracking
Orders sent from webhooks
Server-side, so a closed tab stops costing you a conversion.
The identifier carried through checkout
Via custom data, verified on a real order.
An honest answer about whether to build this
For a store at low volume, the native reporting may be enough and we will say so.

What Lemon Squeezy actually lets you do
What Lemon Squeezy gives you, and its limits.
- 1
Webhooks on orders, subscriptions and refunds
A reliable server-side event source.
- 2
Custom data on checkout
Where the click identifier goes.

Merchant-of-record tax handling
Convenient, and it means the price the customer sees includes tax you never receive.

Hosted and overlay checkout
Neither navigates in a way a page-load trigger sees.
- 5
No native conversion sending
Nothing goes to an ad platform on its own.

Where Lemon Squeezy tracking breaks, in diagnostic order

Compare Lemon Squeezy orders against reported conversions
Per order, for a closed window.
- 03
Check whether the overlay callback is the only trigger
If so, closed tabs are costing you conversions.
- 04

Lemon Squeezy tracking · when not to buy
When you don't need this on Lemon Squeezy
Worth reading before you buy anything, from us or anyone.

- If your orders and platform conversions already reconcile within a few percent, nothing here needs doing.
- If you are not running paid media, skip the ad-platform half entirely.

FAQ
Lemon Squeezy tracking questions, answered
Often not, and that is a real answer rather than a polite one. If you sell a modest volume of digital products and are not running meaningful paid media, Lemon Squeezy's own reporting tells you what you need. This work earns its cost when ad spend is large enough that a measurement error costs more than the build.
As custom data set when the checkout is created. It appears on the order and survives to the webhook. Check one real order to confirm — it takes a minute and it is the failure point.
Because it runs in the customer's browser and a customer who closes the tab the instant payment succeeds never triggers it. The order webhook fires because an order exists, which is a much stronger guarantee.
Pick one and document it. Tax-inclusive pricing means what the customer paid and what you receive genuinely differ, and most reconciliation disputes here are two people comparing two different numbers.
