How Do I Track Lot Expiration Dates?
Lot tracking lets you trace inventory by batch number, expiration date, and supplier.
What Is a Lot?
A lot (or batch) is a group of identical items that were manufactured or received together. Each lot has:
| Field | Description |
|---|---|
| Lot Number | Unique identifier (e.g., "LOT-2025-A001") |
| Product | Which product this lot belongs to |
| Batch Number | Manufacturer's batch code |
| Expiration Date | When the lot expires |
| Manufactured Date | When it was produced |
| Received Date | When you received it |
| Status | Active, Quarantine, Expired, Recalled |
Creating a Lot
- Go to Warehouse → Lots & Batches
- Click + New Lot
- Select the product
- Enter the lot number, batch number, and dates
- Click Create
Receiving with Lot Tracking
When receiving goods, you can assign lot numbers during the receiving process:
- Start a new receiving record
- For each item, enter or scan the lot number
- Enter the expiration date
- The lot is automatically created and linked to the inventory
Expiration Alerts
WareSquared monitors lot expiration dates and alerts you:
- Expiring Soon (within 30 days) — shown on the Expiring Lots dashboard widget
- Expired — lots past their expiration date are flagged and can be quarantined
Important: For medical supplies, cosmetics, and food products, lot tracking with FEFO picking ensures you always ship the soonest-expiring stock first.
