Franking
WooCommerce Canada Post, Australia Post and Royal Mail rates in one plugin
Franking is for WooCommerce shops in Canada, Australia and the UK that ship with their national post.
Inside Franking
Canada Post, live
the Rating API, counter prices - or your contract prices when you add your customer number.
Australia Post, live
the Postage Assessment Calculator, Parcel Post and Express Post.
Royal Mail, by size
each box is a Large Letter, Small Parcel or Medium Parcel by its three sides and its weight, then priced from Royal Mail's online price guide (5 October 2026 prices filled in). 1st and 2nd Class, Tracked 24 and 48, and Special Delivery by 1pm. Change a line the day Royal Mail changes a price.
Your boxes
list them once (inside size in cm, most they may weigh, empty weight in kg). The cart is packed biggest item first, then every box is shrunk to the smallest of yours that still holds it. A product can be marked "ships in its own box".
Honest prices
a service is only offered when every box got a price for it.
When the post does not answer
your fallback rate shows under its own name - checkout is never empty and never accidentally free.
Your way
choose which services to offer, rename them, add a percentage and a fixed amount.
