INVENTORY & WAREHOUSE OPERATIONS
Lot
A lot is a defined group of product units identified together for tracking, handling or traceability.
LOT IN PRACTICE
- Capture the lot
- Preserve it through movements
- Trace stock & shipments
A WORKED EXAMPLE
One SKU. Two lots. Different expiry dates.
A receipt contains 60 units from lot L1 and 40 from lot L2. Both share the same SKU, but their lots remain distinct in stock and shipment records. Reporting only 100 units loses the information needed to identify which customers received L1 if that lot requires investigation.
WHAT THIS MEANS FOR YOUR QUOTE
Make the requirement explicit
Use the same scope and units when comparing providers. Put the agreed responsibility, included work and exception process into the service description.
A LITTLE MORE CONTEXT
Questions about Lot
Is a lot the same as a serial number?
No. A lot normally groups units; a serial number identifies a particular unit within its defined context.
Can one SKU contain multiple lots?
Yes. The item can be the same while lot, expiry or status differs.
