IH Shipping for Australia Post was born out of necessity. While looking for an economical way to manage and sell inventory online using WordPress and WooCommerce, I hit a major roadblock: the inability to calculate accurate shipping without expensive or overly complex third-party plugins.

Instead of compromising, I built this solution from the ground up. This plugin provides a lightweight, API-driven way to get real-time Australia Post rates, including volumetric box packing logic, without the “bloat” of larger enterprise tools.

Key Features:
* Real-time Parcel Post rates via official Australia Post API.
* Built-in volumetric box packer for accurate quoting.
* Simple, “clean-code” setup that won’t slow down your site.
* Tailor-made for Australian small businesses.
