Pirajki Shipping Calculator for WooCommerce

Pirajki Shipping Calculator for WooCommerce solves a common problem: when creating manual orders in the WooCommerce admin, shipping rates are not automatically calculated from the customer’s postcode the way they are on the front end.

This plugin adds intelligent shipping rate lookup directly to the order edit screen:

Auto-calculates rates whenever the shipping postcode changes — no button click needed

Auto-applies the highest rate immediately so you never under-charge

Shows all available methods as a selectable list so you can override the auto-selected rate

Manual fallback — if no rates are found you can enter a label and cost manually

Country auto-detection — correctly resolves Guernsey (GY→GG), Jersey (JE), and Isle of Man (IM) postcodes that the WC admin often leaves as GB

Compatible with Advanced Shipping plugin (WAS_Advanced_Shipping_Method) — queries its condition groups directly

HPOS compatible — works with WooCommerce High-Performance Order Storage

Secure — nonce-verified AJAX, full capability checks, all inputs sanitised

How it works

Open any order in WooCommerce admin

Enter a postcode in the shipping or billing address fields

Rates are fetched and the highest cost rate is applied automatically

All available rates are shown — click a different one and press Apply selected rate to override
