Expiry loss rarely makes noise. It stays quiet: newer lots ship out while older lots inside expire; write-offs come with unclear accountability. Food and chemical operations that track quantity but not batch expiry leave FIFO as wall text. Silent loss often costs more than one incident—no alarm, only year-end shrink.
Batches form at receiving; expiry writes at putaway; outbound locks to rules—pickers cannot "take what is easy."
FIFO Is Scan Discipline, Not Training
WMS recommends locations by expiry or receipt date; pick tasks specify batches. Skip-batch needs reasons: customer-specified lot, quality hold, emergency. Skip rate enters warehouse KPIs. Near-expiry auto-alerts; promotions or returns follow process—not wait for expiry.
- No production or expiry date at receiving—no putaway to good stock.
- Mixed batches forbidden unless process allows and system marks it.
- Write-offs must carry batch—quantity-only lines forbidden.
Silence Comes from Invisibility
The XYN digital intelligence system binds batches, expiry, and outbound rules to inventory transactions—near-expiry gets loud. Food and chemical fear silence, not noise. Silence means rules never entered scanning, only training slides.
Sample one bin and check the expiry on the innermost case. If it is older than the front, FIFO has failed—restart from receiving scans.
