Shopify Cart Transform
Enable dynamic percentage-based warranty pricing with the Cart Transform function.
Shopify Cart Transform
Dashboard → Settings → Integrations → Cart Transform
The Cart Transform function enables percentage-based warranty pricing. When a warranty plan is priced as a percentage of the product price (e.g., 10%), this function calculates and applies the correct warranty price at checkout based on the actual product variant price.
Note Cart Transform is only needed for percentage-based warranty pricing. Fixed-price plans do not require it.
How It Works
Warranty variants in Shopify carry a placeholder price. The actual price depends on which product the customer is buying:
- Product A costs $500 with a 10% warranty = $50 warranty price
- Product B costs $1,000 with a 10% warranty = $100 warranty price
The Cart Transform function runs during cart evaluation, calculates the correct percentage-based price for each warranty line item, and adjusts the price before the cart total is displayed.
Enable or Disable
- Go to Dashboard → Settings → Integrations → Cart Transform
- Toggle the Cart Transform function on or off
Enable when:
- You use percentage-based warranty pricing
- Warranty price should scale with product price
Not needed when:
- All warranty plans use fixed pricing
Note Your Shopify plan must support Shopify Functions for Cart Transform to work.
