Pricing Modes

📈Range-Based Pricing (Tiered)

Configure different prices for specific quantity ranges. Each range can have either a total price or a per-unit price. Perfect for volume discounts and wholesale pricing.

Configuration Example:

Min Qty	Max Qty	Total Price	Per Unit
0	50	$500	$10
51	100	-	$8
101	∞ (unlimited)	-	$5

Example Calculation:

Customer orders 75 units

→ Falls in range 51-100

→ Price = 75 × $8 = $600

JSON Configuration:

{ "mode": "range", "ranges": [ { "min": 0, "max": 50, "price": 500, "unit_price": 10 }, { "min": 51, "max": 100, "price": 0, "unit_price": 8 }, { "min": 101, "max": null, "price": 0, "unit_price": 5 } ] }

➕Incremental Pricing (Every X Units)

Start with a base price and add price hikes every specified number of units. Perfect for products with setup costs or scaling manufacturing fees.

Configuration Settings:

▸
Base Price: $10 (starting price)
▸
Every X Units: 10 (add hike every 10 units)
▸
Price Hike: $5 (amount to add per increment)
▸
Max Hikes: 5 (optional, cap at 5 increases)
▸
Max Total Price: $50 (optional, absolute cap)

Calculation Breakdown:

• 0-10 units: $10 (base)

• 11-20 units: $15 (base + 1 hike)

• 21-30 units: $20 (base + 2 hikes)

• 31-40 units: $25 (base + 3 hikes)

• 41-50 units: $30 (base + 4 hikes)

• 51+ units: $35 (base + 5 hikes, capped)

Formula Logic:

increments = Math.floor((quantity - 1) / every) if (max_hikes > 0 && increments > max_hikes) { increments = max_hikes } price = base_price + (increments * hike) if (max_price > 0 && price > max_price) { price = max_price }

🧮Custom Formula Mode

Write your own JavaScript calculation for maximum flexibility. Access quantity, min, max, and step variables for unlimited pricing possibilities.

Available Variables:

quantity

User input number

min

Minimum value from field settings

max

Maximum value from field settings

step

Step value from field settings

Example Formulas:

Linear with Bonus:

quantity * 10 + (quantity > 50 ? (quantity - 50) * 2 : 0)

$10/unit, plus $2/unit bonus for quantities over 50

Exponential Pricing:

Math.pow(quantity, 1.5) * 2

Price increases exponentially with quantity

Tiered with Maximum:

Math.min(quantity * (quantity < 10 ? 15 : 12), 500)

$15/unit for <10, $12/unit for 10+, capped at $500

Square Footage Pricing:

quantity * 3.5 + (quantity > 100 ? 50 : 0)

$3.50 per sq ft, plus $50 fee for orders over 100 sq ft

• Set "every X units" interval
• Enter price hike amount
• Optionally set max hikes and/or max total price

For Custom Formula:

• Write JavaScript expression in the formula field
• Use variables: quantity, min, max, step
• Test with different quantities using the preview

4. Test Your Pricing

Use the Live Preview feature to test your pricing with different quantities. Enter test values to see the calculated price in real-time before publishing.
