Custom Shipping Rates & Delivery Rules

Shipping prices that account for when you can send an order and when it can arrive.

The problem

An order placed before lunch may be able to ship today. The same order placed later may need to wait, cost more to deliver, or run into a holiday closure. Your checkout prices need to reflect those differences.

What it does

This custom shipping app calculates rates using the order time, shipping calendar, and expected delivery day. One build uses a noon Central cutoff, Monday–Thursday shipping, holiday closures, and different prices by delivery day. It also offers a lower-cost option when a customer can wait until the following week.

The same rate calculations support checkout and invoice quotes, so both use the same rules.

For your store

A custom version could use your cutoff times, time zone, closure calendar, delivery options, and pricing rules. The original schedule is an example of what can be built around your business.
