Install the plugin, create your free account inside WordPress, upload your carrier rate cards, and ShippingIQ calculates your real contracted freight costs at checkout automatically – no separate sign-up step, no manual configuration. **How it works** 1. Install this plugin and go to WooCommerce -> ShippingIQ to create your free account 2. Upload your carrier rate card (CSV or Excel) in the My Carrier tab 3. Set your shipping rules in the Rules tab 4. Your contracted freight is calculated at checkout automatically **What makes ShippingIQ different** Most shipping plugins use their own carrier accounts and add a margin. ShippingIQ uses _your_ contracted rates – so your customers see exactly what you negotiated with your carrier, with no hidden markup unless you choose to add one. **Supported carriers** Any Australian carrier. ShippingIQ’s AI parser handles any rate card layout – Allied Express, Mainfreight, StarTrack, Hunter Express, and more. Upload it as CSV or Excel. If your carrier only supplies a PDF, Pro merchants can convert it to CSV first using the Rate Card Converter at shippingiq.com.au. **Features – included on the free plan** * Real-time freight calculation at checkout * Supports weight-break, basic charge + per kg, and depot-to-depot pricing models * Per-carrier fuel levy – set your carrier’s levy percentage so quotes match your invoices * Per-carrier cubic factor – set the conversion factor your carrier actually uses( default 250) * Origin depot selection for carriers that quote from more than one depot * Free shipping threshold with smart surcharge voiding * Carrier eligibility rules – stop a carrier being offered when an item exceeds its weight or dimension limits * Product tag overrides – force or exclude a specific carrier per product, using ordinary WooCommerce product tags * Cheapest-only or all-carriers display mode * Carrier and rules management directly inside WooCommerce admin – no separate app needed * 100 checkout quotes per month * 5-minute rate caching for performance **Pro plan adds** * Unlimited carriers (the free plan supports one) * Unlimited checkout quotes * Surcharges – add charges such as tail lift or hand unload, with rules that trigger them automatically by weight, length or every consignment * Freight margin – add a percentage or flat amount on top of the carrier rate to cover handling * PDF rate cards – convert them to CSV with the Rate Card Converter at shippingiq. com.au, then upload the CSV here (the plugin itself accepts CSV and Excel on every plan) **Requirements** * A ShippingIQ account – create one free inside the plugin after installing * At least one active carrier with an uploaded rate card * Products must have weight set in WooCommerce (kg) ### External Services This plugin connects to the ShippingIQ API for freight rate calculation and rate card analysis, and to Supabase Auth for account creation and login. ShippingIQ Freight Calculation API What it does: Calculates freight rates based on cart items, destination postcode, and the merchant’s uploaded carrier rate cards. What data is sent: Destination postcode, cart item weights and dimensions, quantity, and the merchant’s ShippingIQ Merchant ID. When data is sent: Every time a customer reaches the checkout page and a shipping rate is requested. API endpoint: https:// soaxvqkkecqzarwmbeip.supabase.co/functions/v1/calculate-freight ShippingIQ Account API (Supabase Auth) What it does: Creates a new ShippingIQ merchant account or authenticates an existing one directly from the WooCommerce admin. What data is sent: Email address and password (signup or login only – entered once by the store owner in WooCommerce -> ShippingIQ). When data is sent: Only when the store owner submits the signup or login form in the plugin settings page. API endpoints: https://soaxvqkkecqzarwmbeip.supabase.co/functions/v1/register-merchant and https:// soaxvqkkecqzarwmbeip.supabase.co/auth/v1/token ShippingIQ Rate Card Analysis API What it does: Analyses your uploaded carrier rate card to detect its pricing structure and extract rates and surcharges. What data is sent: The contents of your rate card file (as text, up to 100,000 characters) and the carrier name you entered. No customer data is involved. When data is sent: Only when the store owner clicks Analyse, and again when clicking Save, in WooCommerce- > ShippingIQ -> My Carrier. API endpoint: https://soaxvqkkecqzarwmbeip.supabase. co/functions/v1/rapid-api AI processing: This rate card content is processed via Anthropic’s Claude API to interpret the rate card structure.

In WordPress admin go to Plugins -> Add New 2. Search for “ShippingIQ” and click Install Now, then Activate 3. In the left menu go to WooCommerce -> ShippingIQ 4. Click Sign Up and create your free ShippingIQ account 5. You will see four tabs: My Carrier, Rules, Surcharges, and Account 6. Go to the My Carrier tab and enter your carrier name 7. Upload your carrier rate card file (CSV or Excel) and your zone file, then click Analyse 8. Review the analysis result and click Save Carrier – your rates are now stored 9. Go to the Rules tab to set your free shipping threshold and display preferences, then click Save Rules 10. Now go to WooCommerce -> Settings -> Shipping 11. Click on your Shipping Zone (e.g. “Australia”) – if you don’t have one, click Add shipping zone, name it “Australia”, and set the region to Australia 12. Inside the zone, click Add shipping method 13. Select ShippingIQ from the list and click Add shipping method 14. Click Save changes 15. Your contracted carrier rates will now appear automatically at checkout when customers enter their postcode Note: Rates will only appear for postcodes covered by your zone file. If no rates show at checkout, check that your zone file was uploaded correctly in the My Carrier tab. #### Plugin Settings * Method Title – label shown to customers at checkout, defaults to “Freight” * Display Mode – show all eligible carriers or cheapest only ## FAQ ### Do I need a ShippingIQ account? Yes. After installing the plugin, go to WooCommerce -> ShippingIQ to create your free account directly inside WordPress – no need to visit shippingiq.com.au. Upload your rate card and configure rules in the plugin. You can also sign in at shippingiq. com.au with the same account to reach a few settings that are not in the plugin, such as carrier eligibility limits. ### Which carriers are supported? Any Australian carrier. ShippingIQ uses AI to parse your carrier’s rate card. Upload it as a CSV or Excel file. If your carrier provides a rate card file, ShippingIQ can use it. ### Do products need weight set? Yes. WooCommerce products must have weight set in kg. Items with no weight are excluded from the freight calculation. If all cart items have no weight, no rates will be shown. ### What dimension units should I use? Set WooCommerce to kg for weight and cm for dimensions (WooCommerce -> Settings - > General). ShippingIQ uses these for cubic weight calculation and overlength surcharge detection. ### How does free shipping work? Set a free shipping threshold in ShippingIQ -> Rules. When the cart value meets the threshold, free shipping is shown. Smart mode voids free shipping if surcharges apply (e.g. tailgate delivery). True mode always shows free regardless of surcharges. ### Can I exclude certain carriers for oversized items? Yes, on any plan. Carrier eligibility limits (maximum weight, length, width and height) stop a carrier being offered when an item exceeds what it can carry. Set them by signing in at shippingiq.com.au with the same account you created in the plugin, then opening the Carriers page. They apply at checkout automatically. ### Can I force a specific carrier for certain products? Yes, on any plan, and entirely inside WooCommerce. Add a product tag of shippingiq- only-[carrier-slug] to force a product onto one carrier, or shippingiq-exclude-[ carrier-slug] to keep a carrier away from it. The slug is your carrier’s name in lowercase with hyphens – a carrier named “Allied Express” becomes shippingiq-only- allied-express. You can also tag a product shippingiq-exempt to stop its cart from qualifying for free shipping – for bulky items that should always be charged freight. ### Can I upload a PDF rate card? Not directly – the plugin accepts CSV and Excel on every plan. If your carrier only provides a PDF, either ask them for a CSV or Excel version, or, on the Pro plan, sign in at shippingiq.com.au and use the Rate Card Converter to turn the PDF into a CSV, then upload that CSV here. ### How many carriers can I add? The free plan supports 1 carrier. Upgrade to Pro at shippingiq.com.au/pricing for unlimited carriers. ### Is there a limit on checkout quotes? The free plan includes 100 checkout quotes per month. If you reach the limit, a “ shipping unavailable” message will show at checkout until the next calendar month. Upgrade to Pro for unlimited quotes. ### Is there a free plan? Yes. The free plan includes one carrier (CSV or Excel rate cards), 100 checkout quotes per month, and all of the settings that keep your quotes accurate – fuel levy, cubic factor, origin depot, free shipping threshold, display mode, carrier eligibility limits and product tag overrides. Upgrade to Pro at shippingiq.com.au/ pricing for unlimited carriers, unlimited quotes, surcharges, freight margin, and the PDF Rate Card Converter. ### What are surcharges and how do the trigger rules work? Surcharges are extra carrier charges such as tail lift, hand unload or an overlength fee. On the Pro plan, open the Surcharges tab to add them as a dollar amount, a percentage, or POA. Each surcharge gets a trigger rule that decides when it applies: never, on every consignment, when a single item is over a weight you set, when the whole consignment is over a weight you set, or when an item is longer than a length you set. Anything ShippingIQ finds in your rate card is added for you and marked Extracted; anything you type in yourself is marked Manual. ### What is the cubic factor and why does it matter? Carriers charge on whichever is greater, actual weight or cubic weight. The cubic factor converts a carton’s volume into that cubic weight. Most Australian carriers use 250, which is the default, but some use 333 or another figure. If yours differs and the factor is left at 250, every quote will be wrong in the same direction. Set it per carrier on the My Carrier tab. This is included on the free plan. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “ShippingIQ – Freight Calculator for WooCommerce” is open source software.

Two unused settings were removed – the shipping method now shows only Method Title and Display Mode. * The Test a postcode tool now shows an itemised breakdown (freight, fuel levy, surcharges, margin and total per carrier) and includes an order value field so you can test your free shipping threshold. * Corrected the description of the shippingiq-exempt product tag: it stops a cart from qualifying for free shipping. Checkout behaviour is unchanged. #### 1.6.0 * Added in-plugin upgrade to Pro: click Upgrade to Pro on the Account tab to go straight to secure checkout, then back into WooCommerce as a Pro merchant. No second sign-in needed. #### 1.5.0 * Added surcharges: create, edit and delete carrier surcharges (such as tail lift or hand unload) and set the rules that trigger them automatically at checkout. Pro feature. * Added freight margin: add a percentage or flat amount on top of the carrier rate to cover handling costs. Pro feature. * Added fuel levy: set a per-carrier fuel levy percentage so quotes match your carrier invoices. * Added cubic factor: set the per-carrier cubic conversion factor (default 250). If your carrier uses a different factor, quotes are now accurate instead of systematically over or under charging. * Added origin depot selection for carriers with more than one depot — required for these carriers to quote correctly. * Improved support for large rate cards, so carriers with many depots or zones are read in full. * Fixed plan detection: if the connection to ShippingIQ was briefly interrupted, Pro merchants could be shown an “upgrade to Pro” notice over features they already had. The plugin now tells the difference between “not on Pro” and “could not check right now”. * Removed the “Priority” checkout display mode. Checkout now offers All carriers or Cheapest only. Stores previously set to Priority will show all eligible carriers. #### 1.4.0 * Fixed the “Test a postcode” tool so it works with the secure login connection introduced in 1.3.0. * Clearer reconnect prompt: if your account is disconnected, the plugin now tells you that checkout rates are affected and asks you to log in again. * Reliability improvement to keeping your checkout connection valid after logging in. #### 1.3.0 * Security improvement: the plugin now connects to your ShippingIQ account using your own secure login session instead of a shared access key. Your carrier and account data is only reachable with your login. * After updating, you will need to log in to ShippingIQ again in WooCommerce -> ShippingIQ. Your checkout keeps showing freight rates in the meantime, so your store is not affected. * Carrier eligibility limits (maximum weight and dimensions) are now applied at checkout, so a carrier is no longer offered for an item it cannot carry. #### 1.2.2 * Renamed to ShippingIQ – Freight Calculator for WooCommerce for clarity * Updated all descriptions to use consistent freight calculation language * Improved rate card upload help text — clarified CSV/Excel only on free plan * Added no active carriers warning banner * Added postcode range editor inside plugin * Added test postcode tool #### 1.2.1 * Improved rate card and zone file upload guidance with download templates and setup guide link * Updated FAQ entries to accurately reflect free plan vs Pro plan features #### 1.2.0 * Added carrier management inside WooCommerce admin – upload rate cards, manage carriers, and activate/deactivate without leaving WordPress * Added AI-powered rate card analysis – upload a CSV or Excel rate card and ShippingIQ automatically detects the pricing model and extracts rates * Added Rules tab inside WooCommerce admin – set free shipping threshold, free shipping mode, and display mode without visiting shippingiq.com.au * Added demo carrier on first signup – an example carrier is created automatically so merchants can test checkout rates immediately * Added monthly quote limit (100 quotes/month) for free tier merchants with real carriers * Fixed free shipping threshold not applying correctly when different cart values shared a cached result * Fixed carrier analysis failing with “Unexpected end of JSON input” due to deprecated Claude model ID #### 1.1.0 * Added in-plugin account signup and login – merchants can now connect their ShippingIQ account directly from WooCommerce without visiting shippingiq.com.au * Merchant ID is now saved automatically on signup or login – no manual entry required #### 1.0.0 * Initial release * Real-time freight calculation at checkout * Support for weight-break, basic charge + per kg, and depot-to-depot pricing models * Carrier eligibility rules (weight and dimension limits) * Product tag overrides (shippingiq-only, shippingiq-exclude) * Free shipping threshold with smart and true modes * Cheapest-only and all-carriers display modes * 5-minute rate caching * (Fuel levy, surcharges and freight margin were calculated at checkout from this release, but could only be configured outside the plugin until 1.5.0.) ## Meta * Version **1.6.1** * Last updated **6 days ago** * Active installations **Fewer than 10** * WordPress version ** 6.0 or higher ** * Tested up to **7.0.2** * PHP version ** 8.0 or higher ** * Tags * [australia](https://wordpress.org/plugins/tags/australia/)[freight](https://wordpress.org/plugins/tags/freight/) [rates](https://wordpress.org/plugins/tags/rates/)[shipping](https://wordpress.org/plugins/tags/shipping/) [woocommerce](https://wordpress.org/plugins/tags/woocommerce/) * [Advanced View](https://wordpress.org/plugins/shippingiq-freight-rates-for-woocommerce/advanced/) ## Ratings No reviews have been submitted yet.
