Split Shipping Rate Selector for Shopify Checkout

78% Confidence Medium Market Hard Difficulty $5k-15k MRR Updated May 18, 2026

The Opportunity

A Shopify app that helps merchants control which shipping rate combinations appear when an order is split into multiple shipments. It would let stores define preferred pairings or rules so customers can reliably choose valid split-shipping options at checkout.

"Merchants using split shipping can offer multiple rates for each shipment but still cannot easily control or switch between valid combined rate combinations, creating checkout confusion and limited flexibility."

Detailed Analysis

Proposed Solution

Provide a rule-based split-shipping engine that maps shipment groups to allowed rate combinations, with an admin interface to configure priorities, exclusions, and fallback logic.

Target Audience

Shopify merchants with multi-origin inventory, preorder/backorder flows, multi-package fulfillment, or complex shipping setups

Competitive Landscape

Shipping rules apps, advanced shipping rate apps, checkout customization apps; specific overlap with apps like Intuitive Shipping, ShipMagic, and Advanced Shipping Rules

Implementation Notes

Needs deep checkout and shipping-rate logic, careful handling of Shopify shipping APIs and split fulfillment scenarios, a merchant rules UI, robust testing across carrier-calculated and flat rates, and fallback behavior when valid combinations are unavailable. Must stay compatible with Shopify checkout limitations and possibly use Shopify Functions or shipping customization where available.

Evidence from Merchants

Real quotes from Shopify community forums

"We have split shipping. We have at least two rates available for both of the shipments but there’s no option to change rates. What causes this?"
