How to Create Dynamic Discount Rules on Shopify (Without Code)

Shopify's built-in discount system handles simple cases — percentage off, fixed amount, free shipping. But when you need tiered pricing, tag-based deals, or discounts that stack intelligently, you hit a wall.

Shopify Functions unlock advanced discount logic at checkout speed. Here's how to use them without writing code.

5 Discount Rule Types You Can Build

1. Tiered Quantity Discount

Reward bulk buying with escalating discounts.

Quantity	Discount
3–5 items	10% off
6–10 items	15% off
11+ items	25% off

Tiers are unlimited — add as many as you need. Target specific collections or apply store-wide.

2. Tag-Based Discount

Give specific customer segments special pricing.

Examples:

• Customers tagged vip get 20% off everything
• Customers tagged employee get 40% off
• Customers tagged wholesale get tiered wholesale pricing

Multiple tag rules can coexist. Rulefy resolves conflicts with a configurable stacking strategy (highest discount wins, or stack them).

3. Collection-Wide Percentage Discount

Run a sale on an entire collection without editing every product.

Example: "Summer Sale — 30% off everything in the 'Clearance' collection."

This targets products dynamically — add a product to the collection and it automatically gets the discount.

4. Buy X Get Y Discount

The classic promotion: buy a certain quantity, get a bonus item at a discount.

Example: "Buy 2 t-shirts, get 1 free from the 'Basics' collection."

Configure the trigger quantity, the reward quantity, and the discount percentage (100% for free).

5. Spend Threshold Discount

Incentivize larger carts with minimum-spend rewards.

Example: "Spend $100+, get 15% off your entire order."

Multiple tiers work too:

• Spend $50 → 5% off
• Spend $100 → 10% off
• Spend $200 → 20% off

How Stacking Works

When multiple discount rules match the same cart, Rulefy needs a strategy:

• Highest wins: Only the single best discount applies (safest for margins)
• Stack all: All matching discounts combine (most aggressive)

This is a global setting you control from the Rulefy dashboard.

Why Not Just Use Shopify's Built-In Discounts?

Shopify's native discounts can't do:

• Dynamic tiers (they're fixed per discount code)
• Tag-based targeting (no customer segmentation)
• Automatic stacking strategies
• Condition combinations (collection + tag + quantity)

Functions fill these gaps, and Rulefy gives you the UI to configure them.

Getting Started

1. Install Rulefy from the Shopify App Store
2. Navigate to the Discounts section
3. Create your first rule (try a tiered quantity discount)
4. Test with the dry-run simulator
5. Activate — the discount goes live instantly

No code, no CLI, no deploy. Just rules that work.
