Why Discount Engine?

Discount Engine is a Shopify app on Shopify Functions that runs inside Shopify's checkout and POS. It reads your discount configuration and applies the right promotion to each cart, with no custom backend to host or maintain.

You design the rules in a guided UI inside Shopify Admin. The engine covers tiers, bundles, split bundles, and trade codes, with control over quantities, ratios, price bases, and whether each discount runs online, in-store, or both.

Flow from Shopify Admin through Discount Engine to checkout and POS

One stack, every place you sell

Scope each discount to checkout only, POS only, or both. The engine detects where the sale is happening and applies the right logic automatically.

🛒

Online Checkout

Discounts apply automatically during the Shopify online checkout flow.

🏪

Shopify POS

Run the same promotions in-store through Shopify Point of Sale.

🔀

Both Platforms

Configure discounts to run on both channels, or restrict to one.

What you configure without the Script Editor

⚙️

Admin first workflows

Build and change promotions in a UI inside Shopify Admin, the same place merchants already manage discounts. Ship updates without the Script Editor or redeploying custom checkout code.

📦

Every major promo shape

Tiers, classic bundles (buy X, get Y), split bundles, and trade codes, each with quantity rules, ratios, and flexible ways to pick source and target lines.

💰

Price or compare at

Discount off the selling price or off compare at (RRP). Percentage or fixed amount, so merchandising matches how your catalog is priced.

Discount types

Four modes cover the promotion patterns teams usually scripted, now as repeatable Admin templates.

Tier Discount

Apply percentage or fixed amount discounts to specific products or variants by tier.
