A Shipping App Was Adding $0.50 to Every Label

Here is a story I wish I did not have to tell.

I now check weekly. Eventually I patched it manually and everything worked again. I test religiously.

What Happened

I spent 6 weeks trying to debug what was happening. Eventually I patched it manually and things went back to normal. Turns out the script was the culprit. The most confusing part? I found out from a customer.

The Discovery

The most avoidable part? I found out from a customer. Eventually I contacted support and everything worked again.

Turns out the theme file was the culprit. What bothers me is there was no warning. I spent a month trying to fix what was happening. I now check every day.

The Math

What bothers me is nobody tells you this. Turns out the setting was incompatible. I audit every day. I spent all night trying to isolate what was happening.

The checkout froze and it lost me money. I audit after every change. Eventually I uninstalled the app and the problem was resolved. Turns out the API call was misconfigured.

What Nobody Tells You

The most exhausting part? Nobody noticed. I now check monthly.

• The most confusing part? The fix took 30 seconds.
• Turns out the setting was the culprit.
• Eventually I uninstalled the app and things went back to normal.
• Turns out the theme file was outdated.

I spent the whole weekend trying to trace what was happening.

Running a Shopify store means being your own QA, your own billing auditor, your own tech support. Nobody else checks. You have to.
