How it works.
From the first condition to a live discount, in four steps.
Discounts Shopify's rules can't express.
Combine cart value, products, customer tags, country and days of the week, with tiers that grow with the basket and a cap on any order.
Replay it on your past orders.
Replay a draft on your store's real orders and see what it would have given, before anyone sees it.
Know what stacks before it stacks.
Every discount already live on your store gets a verdict: would stack, won't stack or can't tell.
Publish from one review step.
One review step shows what changes and cites the run behind it; then it runs inside Shopify's checkout.
Runs in checkout. Reads only what it needs.
What runs where, what a run reads, and what a cap does.
Runs inside checkout
Discounts execute in Shopify's checkout, on every Shopify plan.
Past orders, unchanged
A run reads your order history and changes nothing in your store.
Only what a discount needs
Lines, prices, dates and customer traits. No name or address fields.
A ceiling you set
Cap what any order can receive; an uncertain case gets no discount.
Tested on your orders. Live on your word.
Free during early access.
Plans and prices come with the App Store listing. Every plan starts with a 14-day trial.
