Batches and Expiry Dates

Batch details are used to identify the movement of the inventory in batches or lots. Although this is a requirement primarily of the pharmaceutical industry, the same can be used by other industries who maintain or manufacture perishable goods. Many organizations also purchase in lots in order to monitor the lots purchased individually. Hence, Tally.ERP 9 has used the term Batch/Lot.

Batches/Lots are also often used to monitor the date of manufacture , date of receipt or the expiry date .
