This article outlines the most common issues users may encounter when using the Parcel Freight app with Shopify, along with recommended solutions.

1. Shipping Rates Not Displaying at Checkout #

Possible causes:

• Carrier-calculated shipping is not enabled in your Shopify plan
• Products are missing weight or dimensions
• Loadlink Live Rates has not been added to your shipping profile
• The entered address is incomplete or invalid
• API credentials are incorrect or expired

What to check:

• Go to Settings → Shipping and Delivery → Shipping Profiles and confirm that Loadlink Live Rates is added
• Open each product and confirm weight and size fields are populated
• Go to Apps → Loadlink and confirm API credentials are saved
• Test with a known valid Australian address

2. Inaccurate Rate Calculations #

Possible causes:

• Product data is incorrect or inconsistent
• Pickup or delivery is set to residential when it should be commercial
• Rates are being adjusted by another app or script

What to check:

• Review each product’s shipping details
• Check your app settings for building type configuration
• Disable other shipping apps and retest

3. No Shipping Options Available #

Possible causes:

• Shipping zone does not cover the entered destination
• All items in the cart are missing required freight data
• Address is outside the supported service area

What to check:

• Confirm your shipping zone includes Australia or relevant postcodes
• Ensure each product in the cart has weight and dimensions
• Try a different address within a metro or regional area

4. App Fails to Return Rates for Bundled or Digital Products #

Reason:
Parcel Freight only supports physical products with valid shipping data. Virtual or digital products will not return freight quotes.

Solution:
Exclude virtual products from shipping or ensure at least one physical product with shipping data is in the cart.

5. Conflicts With Other Apps #

Symptoms:
Checkout fails to load rates or displays unexpected options.

What to check:

• Identify any active apps modifying checkout or shipping
• Disable these apps one at a time to isolate the conflict
• Retest after each change

If problems persist, contact Loadlink support with the following details:

• Store URL
• Affected product(s)
• Example shipping address
• Screenshot of the checkout issue (if applicable)
