A $95,000 inventory variance.
The whole ops team was convinced product had walked out the door.
It hadn't.
Two data fields were entered wrong during a system migration.
Wrong pounds-per-case values on two products.
That's it.
Those two fields quietly broke every number downstream.
Every quantity report.
Every reorder recommendation.
Every valuation.
The inventory was sitting in the warehouse the whole time.
The system just couldn't see it.
I keep seeing this same pattern in multi-location Shopify brands.
Not theft, fraud, or a warehouse problem.
A transfer that left one location and never got confirmed at the other end.
A return that landed in the wrong place in the system.
An adjustment someone made without a reason code and that person isn't there anymore.
Small things. Each one feels harmless in the moment.
Six months later the system says one number and the warehouse says another and nobody knows which one to trust.
The problem was never on the warehouse floor.
It was in the data that was supposed to describe it.
Before you assume inventory is missing - check the process.
Before you assume the process failed - check the data.
What's the oldest discrepancy sitting in your system right now that everyone has just quietly accepted as normal?
