Negative inventory isn't just a weird number — it's a symptom. It usually means a product oversold while "continue selling when out of stock" was on, or that a stock count was missed somewhere. Left alone, negative counts distort your reorder decisions and hide real availability problems.
Why they're easy to miss
Shopify will happily show negative stock, but it won't proactively flag it. You'd only notice by scrolling inventory and spotting a minus sign — which nobody does regularly. So negative counts sit there, quietly throwing off your numbers.

Claude lists every variant below zero, with the location and how far negative it is, so you can investigate the cause — an overselling setting, a missed count — and reset them to a correct figure.

Why it keeps your data honest
Your inventory numbers are only useful if they're accurate, and negative counts are a clear sign something's off. Catching them regularly — and fixing the underlying setting — keeps your stock data trustworthy, which everything from fulfillment to forecasting depends on.
