How to Master Batch Mixing and FIFO for Short‑Shelf Products in Warehouses

This guide explains how to handle batch mixing of short‑shelf‑life items in warehouses and stores by establishing clear batch identifiers, maintaining batch‑level inventory ledgers, applying dynamic expiration calculations, and enforcing FIFO through precise inbound recording, storage adjustments, outbound prioritization, regular cycle counts, and staff training to minimize waste and improve turnover.
