Why Serial Numbers Matter

Warranty Fraud

Customer claims warranty on a product you never shipped them. Without serial tracking, you can't verify the claim.

Return Fraud

Customer returns a different unit than what you shipped. Serial tracking catches the swap immediately.

Asset Tracking

High-value equipment needs item-level tracking. Know exactly where each unit is in your supply chain.

How Serial Tracking Works in Fulfil

Serial numbers are a special case of lot numbers where each "lot" contains exactly one unit.

Key Capabilities

  • Scan at receiving

    Capture serial numbers when inventory arrives. Each unit gets a unique identifier in the system.

  • Scan at packing

    Verify the correct serial number is packed for each order. System blocks wrong items.

  • Shipment history

    Look up any serial number to see which customer received it and when.

  • Return validation

    When processing returns, verify the serial matches what was originally shipped.

Common Questions

What's the difference between lot numbers and serial numbers?
Lot numbers group multiple units with shared characteristics (same production batch). Serial numbers uniquely identify a single unit. In Fulfil, serial numbers are implemented as lot numbers where each lot contains exactly one unit.
Can I track serial numbers without scanning at every step?
For warranty validation without full tracking, you can record serial numbers in shipment notes. The packer scans or notes the serial number on the outbound shipment. When a customer initiates a return or warranty claim, look up the original shipment to verify the serial matches.
Does serial tracking slow down packing?
It adds one scan per serialized item. For high-value products where fraud prevention matters, this tradeoff is worthwhile. For lower-value items, consider whether the protection justifies the additional labor. Many brands only serialize their highest-value SKUs.
