# Why am I suddenly overselling on Amazon/Flipkart even though I input stock correctly?

**Overselling is a symptom of growth — and a signal that your operations have outgrown manual updates.**

Marketplaces do their own stock polling, and if they fetch your inventory even a few minutes late during a surge,
 you may end up selling the same unit twice.

Returns, damaged stock, and slow pick confirmations only worsen the issue.
