More Accurate Shipping Costs. Smarter Packaging Calculations.

Overview

Shipping costs are one of the most common reasons customers abandon their carts. If rates seem too high, customers often leave before completing a purchase. If rates are too low, it starts cutting into profit margins.

Interdimensional provides precise calculations based on real-world packaging strategies, filling the gap in BigCommerce native functionality at a lower monthly fee than competing apps.

The app calculates shipping costs based on dimensional weight and packaging logic. It provides a more accurate estimate of shipping by using product dimensions, weight, and quantity to determine rates. By applying dimensional logic, the app improves both accuracy and trust at checkout.

How It Works

Once installed, the app integrates with your BigCommerce store and becomes a selectable shipping method. During checkout, it calculates the most efficient box setup and retrieves live rates from connected carriers based on that packaging. Customers see shipping rates that better reflect actual costs, helping reduce cart abandonment and improving profitability.
