Overview: Managing shipping charges and exclusions in coreFORCE

Purpose

This article provides a high-level summary of the different ways coreFORCE calculates, overrides, and excludes shipping charges. It covers the main configuration areas and highlights where to find more detailed guidance for each topic.

Core shipping calculation process

coreFORCE calculates shipping charges using a layered approach that can include:

• Base item charges such as flat rates, additional item fees, or percentages of cart value.
• Weight-based charges that add costs when the total cart weight exceeds a defined minimum.
• Category, department, and product type charges that apply when qualifying items are in the cart.
• Distributor and location-based charges to account for fulfillment from multiple sources.
• Minimum and maximum charge limits to keep rates within your defined range.

Shipping charge exclusions

In certain cases, coreFORCE intentionally skips shipping charge calculations, such as when:

• All items are virtual products.
• Products are restricted from being shipped to a specific location.
• Category or department restrictions apply.

Override options are available in coreFORCE Advanced to bypass some restrictions.

Overriding fixed shipping charges

Fixed shipping charges can override standard calculations. These charges can be set:

• Per product.
• Per manufacturer.
• For specific promotions.
• For specific shipping methods.

When configured, these charges take priority and are excluded from additional shipping calculations.

Shipping method exclusions

Not all shipping methods appear for every order. Methods may be excluded based on:

• Order total thresholds (minimum or maximum cart value).
• Shipping location restrictions (country, state, postal code).
• Pickup-only items that remove all non-pickup methods.

EasyPost shipping calculation

coreFORCE integrates with EasyPost to retrieve real-time carrier rates. This calculation is available when:

• Products meet minimum weight requirements.
• Products are available from a local or designated distributor source.

You can also apply flat-rate or percentage adjustments and set maximum package weight limits.

Summary

By combining layered shipping charges, fixed-charge overrides, and exclusion rules, coreFORCE provides flexible and accurate shipping rate management. Understanding how these components work together ensures that your store displays rates that are fair, competitive, and compliant with your operational rules.
