<p>FIFO (first in, first out) inventory management seeks to value inventory so the business is less likely to lose money when products expire or become obsolete.</p>
<p>As a cashier the system should help me detect those items that were first received or have a closer expiration date over those that have a later expiration date. If I scan an item with multiple batches, it should then show me the batches and expiration dates accompanied. The one closest to expire i.e First In should show up first.</p>
