Custom Shipping Rate Connection

Bring your custom shipping calculations into checkout.

The problem

Your business may already have a tool that calculates shipping prices. Customers still need those prices to appear when they place an order, and the connection needs to stay current when the tool moves or changes.

What it does

This integration registers a custom rate app with Shopify and updates an existing connection when its address changes. It checks for a matching registration first, so repeating the setup does not create another copy.

It is a supporting part of a custom shipping solution: the rate app calculates the prices, and this connection makes them available to checkout.

For your store

I can build the connection around your shipping app and hosting setup, either as part of a new shipping solution or to connect an existing rate calculator.
