Dynamic pricing rules

This guide walks through building a dynamic pricing system that calculates discounts, applies promotions, and determines final prices based on customer and order data.

Decision flow

Example input

{
  "customer": {
    "tier": "gold",
    "yearsActive": 3
  },
  "order": {
    "subtotal": 450,
    "itemCount": 12
  },
  "promoCode": "SUMMER20"
}

Step 1: Customer tier discounts

Create a decision table for base discounts by customer tier: Logic:

Platinum customers always get 20%
Gold customers get 15% after 3 years, 12% before
Silver customers get 10% after 2 years, 8% before
Everyone else gets 5%

Step 2: Volume discounts

Add another decision table for quantity-based discounts:

Step 3: Promotional codes

Handle promo codes with another table:

Step 4: Calculate final price

Use an expression node to combine all discounts: Key logic:

Calculate savings from each discount type
Cap total discount at 40% to protect margins
Round to 2 decimal places

Testing scenarios

Scenario	Expected result
Gold customer, 3+ years, 12 items, no promo	15% tier + 5% volume = 20% off
New customer, 5 items, NEWUSER code	5% tier + 15% promo = 20% off
Platinum, 50 items, SUMMER20	Capped at 40% (would be 50%)

Output structure

{
  "baseAmount": 450,
  "tierSavings": 67.50,
  "volumeSavings": 22.50,
  "promoSavings": 90,
  "totalDiscount": 180,
  "finalPrice": 270
