01Overview

Reorder, hide, and rename shipping rates at checkout.

Customize how shipping options appear at checkout. Reorder carrier-returned rates, hide ones you don't want surfaced, rename for clarity. Pro tier adds conditional rules — by item count, total, state, product, or collection.

02Features

What it does, what it doesn't.

Narrow scope, deep integration. We don't try to be a platform — we solve one problem well, on Shopify.

Reorder + hide + rename
Drag rates into the order you want customers to see. Hide the ones you don't want surfaced. Rename "USPS Ground" to "Standard (3-5 days)" for plain-English checkout.
Cheapest-pinned
Shopify policy requires the cheapest rate to be selected by default. Shipping Sorter respects this — your reordering applies to everything below the cheapest.
Conditional rules (Pro)
Layer rules on top of the default order. Match by item count, cart total, ship-to state, product, or collection — each rule reorders, hides, or renames independently.
Native checkout
Runs as a Delivery Customization Function inside Shopify's native checkout. No theme changes, no cart.js shenanigans, no breaking on theme updates.
