Lot Tracking and Expiration Date Management for 3PL Warehouses

What lot tracking actually means on our floor

Lot tracking means every carton that comes through our dock gets tied to a batch number before it's put away, so we can trace any unit forward to the order it shipped on, or backward to the inbound shipment it arrived on. That's the whole definition. It isn't a software feature you switch on later — it's a receiving habit.

Most brands start asking about this after something already went wrong: a customer complaint, a retailer asking which batch shipped, an expiration date that surfaced too late. By then it's a forensic exercise instead of a five-minute lookup. If you're moving supplements, skincare, food-adjacent products, or anything else with a shelf life or a recall risk, batch discipline needs to be in place before the first pallet lands, not after the first complaint.

Lot-number and expiration-date tracking runs through the same KAK WMS dashboard every client account already has. It isn't a separate module or a custom line item — it's part of how we receive and store inventory for any brand that needs it.

Where it starts: receiving and quarantine

Good lot control starts on the dock, before anything is called "available" inventory. If a carton goes into a bin without a batch number attached, or a damaged case gets shelved next to good stock, the rest of the system is compromised no matter how good the software is.

1. Inbound cartons are checked against the packing list and assigned a lot number and location before they're released to the pickable pool.
2. Anything with damaged packaging, a missing or unreadable date code, or a mismatched count goes into a hold location instead of open stock.
3. We log the expiration or best-by date on receipt, not later, so rotation logic has something to work from from day one.
4. Held inventory stays out of picking until someone actually makes a call on it: release, return to vendor, or write off.

Receiving runs $20 per pallet ($5 per carton). That fee covers the same disciplined check-in whether the inventory needs lot tracking or not — we just log more per pallet when it does.

FIFO vs. FEFO — and why we default to FEFO for dated goods

FIFO rotates whatever arrived first. FEFO rotates whatever expires first. For anything with a shelf life, those aren't the same thing — a pallet that arrived later can carry an earlier expiration date than one that's been sitting for weeks, especially when you're sourcing from more than one production run or supplier.

We default to FEFO for anything with a printed expiration or best-by date, because receipt order alone doesn't protect against shipping a near-expired unit while an earlier-received, longer-dated unit sits in the back of the same location.

What it actually costs to run dated inventory through us

Lot and expiration tracking has no separate line item — it's built into receiving and storage. The rates below are the same published prices every client pays; dated inventory doesn't carry a surcharge.

Storage is billed per month, not a flat monthly rate — you pay for the fraction of the month you actually use, which matters if you're rotating dated stock in and out faster than a full month.

How lot control touches Amazon prep, DTC orders, and returns

Lot control isn't just a warehouse-management concern — it decides which batch goes out on which channel. If the same SKU ships to Amazon FBA, direct Shopify orders, and a retail account from the same storage location, we need to know exactly which lot each channel drew from.

For Amazon FBA prep, that matters before the box ever leaves Houston — the unit gets received, dated, and separated correctly before it's labeled and forwarded at $0.75/unit. Loose batch control at receiving just carries straight through to the FBA shipment.

For DTC orders, correct lot assignment means customer service can answer "which batch did I get" without guessing, and a return can be traced back to the lot it was picked from. Returns run $1.50 each with inspection included, so a unit coming back from a flagged lot gets caught before it's put back into available stock.

Before sending us dated inventory for the first time, it helps to have answers ready for:

• FIFO or FEFO rotation for this SKU
• What counts as a hold-worthy defect — damage, missing date code, count mismatch
• Which sales channels can receive this inventory and which can't
• The return-inspection rule before anything gets restocked
• Who to call, and how fast, if a lot needs to be pulled

None of that changes our published rates. There's no setup fee to turn lot tracking on, no minimum order volume, and no contract — it's month-to-month like everything else we run.

What good lot visibility buys you when something goes wrong

The payoff shows up when you need an answer fast. If a customer flags an issue, we can trace the likely batch without treating your entire inventory position as suspect. If a retailer asks which lot shipped on a given date, the answer comes from the receiving record, not a manual reconstruction of pick tickets.

It also helps with routine decisions, not just emergencies. Knowing which lots are closest to expiring lets you decide whether to push them through a promotion, move them to a faster-moving channel, or quarantine them — while it's still a planning decision instead of a customer complaint.
