Perishable stock does not fail loudly. It looks fine until the day it is suddenly worthless. BatchTrack adds the missing layer. Give any product or variant an expiry date, an optional lot number, and a quantity. One product can hold several batches with different dates, each stored separately. The dashboard sorts every batch soonest-first, with 7, 30, and 90-day and expired filters. Set a threshold and get an email digest of what is expiring, so you can act in time.
