A/B Testing Shipping Rates with IntelliGems + Corso

Getting Started

Using our integration with IntelliGems, brands can now A/B test their shipping prices directly in Shopify Checkout. This gives you powerful insight into how different price points impact conversion, order volume, and shipping revenue—all without needing custom development.

Setup Steps

1. Create Your Test in IntelliGems

Inside the IntelliGems Admin, create a new test with at least three variants:

Control group
Higher-priced group
Lower-priced group

Once the test is created, go to Show Info to grab the Test Group IDs for each variant.

2. Add IntelliGems Group IDs to Corso

In the Corso Admin, navigate to:

Shipping Plus > Rate Modifications

For each group ID, create a corresponding rate modification:

Control Group: $2 markup
Higher Group: $3 markup
Lower Group: $1 markup

Paste the IntelliGems Test Group ID into each rule so Corso can modify rates based on which group the customer is bucketed into.

3. See It in Action at Checkout

When a customer adds an item to their cart, IntelliGems appends a hidden line item attribute with their assigned Test Group ID.

At checkout, Corso reads that ID and dynamically modifies the shipping rate based on the rules you’ve set.

Rates are adjusted in real time per customer, based on their A/B test group.

Common Modifications to Test

Price changes (e.g., $1 vs. $3 shipping)
Rate name or description updates
Different service levels (Standard vs. Express)
Free shipping thresholds and how they affect conversion

Optimize shipping revenue without hurting conversion
Make pricing decisions backed by real A/B data
