Shopify Shipping keeps undercharging customers

Has anyone had issues with Shopify undercharging shipping costs?

Hi

Yes, this can happen sometimes due to shipping settings, rate misconfigurations, or third-party shipping apps. I’ve helped several store owners resolve similar issues by reviewing their shipping zones, weight-based rules, and carrier settings.

If you want, I can take a look at your setup and help identify why Shopify might be undercharging and ensure your shipping rates are accurate.

Best regards,

Thank you! Can you point me where to look?

Thanks!

@bellesavonvt SEARCH first, it’s a rule so you show you respect others time in collective efforts and respect your own time in using what already exists.
e.g. https://community.shopify.com/search?q=undercharging+customers+shipping , or undercharge , wrong rates etc etc etc keywords

Don’t engage with bots telling you what you want to hear.

Hi @bellesavonvt

Review your shipping profiles and make sure every item is assigned to the profile with the correct weight and dimensions. Inspect the overlap between the price and weight based rules. If you are using carrier rates, make sure all measurements for your products are entered. Testing combinations of two carts or more may reveal misconfiguration that causes Shopify to charge less for shipping.

Thanks! It’s just odd that it started all of a sudden, it used to be correct.

Thank you!!

Are you still having this issue? Are you using Shopify Shipping? If so, they have a couple limitations that could cause rate inaccuracy, especially on multi-quantity orders.
