How do I ensure my inventory optimization with warehouse management system software is compliant with lot expiration tracking?

To make your inventory optimization compliant with lot expiration tracking in a warehouse management system (WMS), you need both the right system configuration and the right operating controls. Here’s a practical checklist:

1) Capture lot/expiry data at receiving

• Require lot number, manufacture date, and expiration date at inbound receiving.
• Make these fields mandatory in the WMS for any lot-controlled item.
• Validate data format and prevent receiving if expiry is missing or invalid.

2) Use lot-controlled item master settings

• Mark applicable SKUs as lot-controlled or expiration-controlled in the item master.
• Define rules by item:
  • shelf life
  • minimum remaining shelf life
  • quarantine period
  • whether partial lots can be picked
• Set different rules for regulated vs. non-regulated products.

3) Enforce FEFO in allocation

• Configure the WMS to allocate inventory using FEFO (First Expired, First Out) rather than simple FIFO.
• Ensure pick logic always selects the lot with the earliest expiration date that still meets customer or regulatory requirements.
• Add exceptions only with approved authorization.

4) Put expiration-based replenishment rules in place

• Use forecast and inventory aging data to avoid overstocking items nearing expiry.
• Set reorder points based on:
  • demand velocity
  • remaining shelf life
  • lead time
  • safety stock
• Trigger alerts when stock is projected to expire before sale.

5) Track lot status through the lifecycle

• Maintain lot status values such as:
  • available
  • reserved
  • quarantined
  • damaged
  • expired
  • recalled
• Prevent picking or shipping from expired or quarantined lots.

6) Set cycle count and audit controls

• Include lot/expiry verification in cycle counts and inventory audits.
• Reconcile physical labels with system records regularly.
• Investigate and correct mismatches immediately.

7) Add expiry alerts and dashboards

• Create alerts for lots nearing expiration at configurable thresholds, like:
  • 90 days
  • 60 days
  • 30 days
  • 7 days
• Track aging inventory by SKU, location, and lot.
• Review slow-moving inventory so it can be discounted, reworked, transferred, or scrapped before expiry.

8) Control shipping and order validation

• Block shipment of expired lots automatically.
• Add customer-specific compliance rules if some customers require a minimum remaining shelf life at delivery.
• Validate expiry at pick, pack, and ship stages.

9) Maintain traceability and recall readiness

• Ensure the WMS can report:
  • where each lot came from
  • where it is stored
  • which orders received it
• Test recall procedures regularly so you can isolate and trace affected lots quickly.

10) Document SOPs and train staff

• Write SOPs for receiving, labeling, putaway, picking, returns, and disposal.
• Train warehouse staff not to override lot rules without approval.
• Require exception logging for any manual adjustments.

11) Integrate quality and compliance checks

• If you operate in a regulated industry, connect the WMS with QA/QC or ERP processes.
• Put suspect or nonconforming lots on hold until released.
• Retain records according to regulatory requirements.

12) Validate the system with testing

Test scenarios such as:

• receiving a lot with missing expiry date
• attempting to pick expired inventory
• FEFO allocation across multiple lots
• partial lot depletion
• recall lookup by lot number
• customer order with minimum shelf-life requirement

Best-practice controls summary

Your WMS should:

• require lot and expiry data
• allocate by FEFO
• block expired inventory
• alert on aging stock
• maintain full traceability
• support audit trails and recalls

2. a compliance SOP template, or
3. a FEFO inventory policy example.
