### What is Shipping Rates Rules & Zones?

This Octolize app lets merchants build custom shipping zones by postcode, city or region, with advanced calculation rules based on weight, price, quantity, SKU, tag or time of day. It carries the **Built for Shopify** badge and shows a 4.7/5 rating on 36 reviews, a smaller sample than the other apps in this list. It's developed by Octolize, based in London, UK, and launched in September 2024.

### How does the app work on a Shopify store?

Merchants build zones by postcode, city or region, then configure "when-then" conditional rules, combinable with AND operators. Multiple shipping methods can be offered per zone, with automatic hiding under specific conditions. The app is currently English-only and requires Shopify's Carrier Calculated Shipping API to function properly, a technical requirement worth checking before installing.

### Why choose this app over another shipping-zone app?

The "when-then" conditional logic, combinable with AND operators, is more flexible than the simple additive rules some competitors offer. One review specifically mentions the app's ability to handle UK offshore addresses outside standard zones, a fairly niche use case that few general-purpose apps handle well. The still-limited review count (36) and recent launch make it worth testing directly how stable rate display is at checkout, an issue one other review mentions before it was resolved by support.

### What are the 3 main features of the app?

1. **Custom shipping zones** by postcode, city or region.
2. **"When-then" conditional logic**, combinable with multiple operators.
3. **Automatic hiding of shipping methods** under defined conditions.
