Fix shipping errors fast (without guesswork)

Fix shipping errors fast (without guesswork)

When shipping breaks, conversion and support tickets spike. Here’s how we diagnose and fix quickly.

Start with the matrix

Most issues trace back to misaligned rules: product shipping categories, weight/dimensions, postcode coverage, or missing backup rates. Reproduce the error with a known basket, postcode, and method to isolate the root cause.

Work the layers

Check product-level settings first, then global shipping methods, then carrier availability. If a method isn’t appearing, validate your conditions and make sure fallback logic exists (e.g., flat rate when APIs fail).

Prevent it next time

Create a pre-deployment test pack: 10 common postcodes, 5 basket types (light, heavy, bulky, mixed, regional), and run it before every change. Document exceptions so staff can resolve customer queries confidently.

If you’re stuck chasing a “Shipping not available to selected location” error, we can help. Contact us for a rapid triage.
