Conditional Pricing (Premium)

Premium featureConditional formulas are available on premium plans.

Conditional formulas allow you to apply if / then / else logic to your pricing. This makes it possible to calculate prices differently based on customer input, thresholds, or selected options.

What are conditional formulas?

A conditional formula evaluates one or more conditions and applies a formula only when those conditions are met.If none of the conditions match, a default (else) formula is used.

This allows you to create advanced pricing rules such as:

• Tiered pricing

• Surcharges above certain values

• Minimum or maximum pricing

• Option-based logic

Structure of a conditional formula

A conditional formula consists of:

1. One or more conditions

2. A Then formula (applied when the condition is true)

3. An Else (default) formula (applied when no conditions match)

Conditions are evaluated from top to bottom; the first matching branch wins.

Conditions

Each condition is built using variables, comparison operators, and optional logical operators.

Available comparison operators

• is greater than

• is less than

• is greater or equal

• is less or equal

• is equal to

• is not equal to

Logical operators

• AND (all must be true) – all comparisons must be true for the condition to match.

• OR (at least one true) – at least one comparison must be true for the condition to match.

Variables in conditions

Conditions can reference:

• Form field values (from Step 1)

• {key}_optidx for Dropdown, Radio, Swatch, Font and Color fields – zero-based index of the selected option (only available in conditions, not in the regular formula)

• Product price and numeric metafields

• Computed properties (custom variables)

• TRUE and FALSE constants for comparing checkbox-style booleans

Example:

width > 200 AND height > 150

Then formula

The Then formula defines the price calculation that is applied when the condition is true.

The same rules apply as for regular formulas:

• Must return a numeric value

• Can use all formula variables, including computed properties and math helpers (Math.min, Math.max, Math.ceil, Math.floor, Math.round)

Example:

(product_price + area * 1.2)

Else (default) formula

The Else formula is applied when none of the conditions match.

This formula is required and acts as a fallback to ensure a price is always calculated.

Example:

product_price + area

Per-branch variable overrides

Each condition branch can override the value of a computed property (custom variable). The same variable name then resolves to a different formula depending on which branch matched.

This is useful for things like:

• A Discount variable that is 0 by default but price * 0.10 for VIP customers.

• A Surcharge that depends on a size threshold.

The override only applies inside the matching branch; outside the branch the variable falls back to its base formula.

Multiple conditions

You can add multiple conditions using Add condition. Important behavior:

• Conditions are evaluated in order

• The first matching condition is applied

• Remaining conditions are ignored

This allows you to create tiered logic such as:

1. Large size pricing

2. Medium size pricing

3. Default pricing

Switching between formula modes

You can switch between Single formula and Conditional formulas (Premium). Switching back to a single formula disables conditional logic and uses one formula for all cases.

Common use cases

• Higher price for large dimensions

• Extra fee when a specific option is selected

• Minimum price enforcement

• Different pricing per quantity range

• Customer-tag based discounts via per-branch variable overrides

Best practices

• Keep conditions simple and readable

• Avoid overlapping condition ranges

• Always define a safe default formula

• Test with realistic values using preview mode

💡 Tip:If your pricing logic starts to feel complex, conditional formulas combined with computed properties keep calculations readable and maintainable.
