One pricing engine
The builder quotes it. Checkout charges it.
One pricing core prices the admin preview and the storefront, and runs inside Shopify Functions at checkout. Test vectors pin every case to the cent.
How it works
01One coreA single pricing engine with zero dependencies defines every set and ladder rule.
02EverywhereIt prices your admin preview and the storefront builder, cart and tray.
03At checkoutA port of the same engine runs in Luxe's Cart Transform and Luxe Rewards discount, Shopify Functions.
04PinnedGolden test vectors check every consumer to the minor unit on every change.
What makes it different
| Capability | In Luxe | Worth checking in any app |
|---|---|---|
| Who changes the price | Only Shopify Functions; the storefront predicts | Does the price depend on theme JavaScript? |
| Consistency | Builder, cart and checkout share one engine | Can the cart and checkout disagree? |
| Without JavaScript | Checkout still prices the set | What happens if a script fails? |
| Monitoring | The Luxe drawer watches for price mismatches | Would you know if prices drifted? |
Framed by capability. We don't name other apps or quote their prices.
Questions
What if a shopper edits the cart some other way?
Checkout re-validates every set through the Functions, so the price is still right.
Do discount codes still work?
Yes. Shopify decides how codes combine with Luxe Rewards, as you configure.
