Discount Configuration in Quantity Breaks

This article defines the configuration process and backend logic for setting up quantity break offers. It details how the system evaluates product eligibility, applies different discount mathematical models (percentage vs. fixed amount), and handles the live calculation of tiered pricing.

1. Configure Product Targeting The system must first evaluate cart contents against the configured target rule to determine eligibility.

• IF the offer should apply to the entire store catalog, THEN select all products.
• IF the offer should apply only to explicitly chosen items, THEN select specific products.
• IF the offer should apply to the catalog with exceptions, THEN select all products excluding a few.

2. Configure Discount Type Navigate to discount configuration to define the calculation rule the system will use to reduce the price.

• IF the price should be reduced by a relative rate, THEN select percentage.
• IF the price should be reduced by a strict currency value, THEN select fixed amount.

3. Define Discount Tiers Establish the exact "If/Then" relationships between the quantity of items purchased and the specific discount value applied.

• Enter the numeric discount amount for each tier.
• System Display Logic: As numeric values are entered, the system routes this data into a live preview widget. IF a tier value is updated, THEN the widget instantly recalculates and displays the original price alongside the newly discounted price.

4. Save Configuration

• Click save to commit the discount logic to the live environment.

4. Constraints & Edge Cases

• Fixed Amount Calculation Constraint: IF a fixed amount discount is utilized, THEN the system subtracts that currency value from the total combined price of the items in that quantity tier. It does NOT apply the fixed discount to the individual unit price of each item.

5. Example Scenarios

Scenario A: Percentage Discount Logic

• Base Item Price: 5.99
• Tier 1 Condition: Quantity = 1. Rule = 5% off. (System calculates 5% of 5.99. Live preview displays: 5.69)
• Tier 2 Condition: Quantity = 2. Rule = 15% off.
• Tier 3 Condition: Quantity = 3. Rule = 25% off.

Scenario B: Fixed Amount Discount Logic

• Base Item Price: 5.99
• Tier 1 Condition: Quantity = 1. Rule = $1 discount. (System calculates 5.99 - 1.00. Live preview displays: 4.99)
• Tier 2 Condition: Quantity = 2. The combined base price is 11.98. Rule = $3 discount. (System calculates 11.98 - 3.00. Live preview displays: 8.98)
• Tier 3 Condition: Quantity = 3. The combined base price is 17.97. Rule = $5 discount. (System calculates 17.97 - 5.00. Live preview displays: 12.97)
