How to Create Dynamic Pricing Relationships

Goal: Link one pricing plan’s minimum and maximum values to another plan’s live price, ensuring all related products stay aligned while preserving independent price testing. 

Overview

The Relationships feature allows you to bind another plan’s minimum and maximum prices to the current plan’s price. You can define these limits using either fixed dollar values ($) or percentage values (%).

As the parent plan’s price changes, the linked (child) plan’s min and max update automatically — ensuring it always stays within your defined range.
The child plan’s live price remains independent but is constrained to operate within those dynamic limits.

 

Steps

Step 1: Access the Relationships Tab

  1. Open the desired pricing plan in your Trellis dashboard.

  2. Navigate to the Relationships tab.

Click the “+” button to create a new relationship.

 

Step 2: Add a Relationship

  1. In the relationship window, search for the plan you want to bind.

  2. Select it — this plan becomes the Child, while your current plan acts as the Parent.

    • The parent’s current price determines the dynamic limits (Min/Max) for the child plan.

  3. Click Save Relationship to link the two plans.

 

Step 3: Set Relationship Rules

  1. Define how the Child plan’s Min and Max prices will follow the Parent plan’s price.

  2. Choose between a $ offset or a % offset to set how far above or below the Parent’s price the Child’s limits should stay.

  3. Save your changes.

These settings create dynamic boundaries — the linked plan’s Min and Max values automatically adjust as the parent price moves.
However, the child plan’s live price can still fluctuate within that defined range.

 

 

Example Use Case: Different Pack Sizes

When a product is sold in multiple pack sizes (e.g., single unit, 3-pack, 6-pack), you can use relationships to keep consistent price differences:

  • Set the single unit plan as the Parent.

  • Bind the larger packs as Child plans.

  • Define Min/Max boundaries tied to the single unit’s price.

This ensures price consistency across all pack sizes while allowing each to adjust independently within safe limits.

 

💡 Tip:
 Use relationships to prevent large pack discounts or small pack markups from drifting too far apart. This maintains brand consistency and avoids pricing confusion across product variations.
