Preparing Your WMS for Rapid Product Growth: Batching, Lot Control, and Traceability

Preparing Your WMS for Rapid Product Growth: Batching, Lot Control, and Traceability

Hook: When SKUs multiply and batch sizes jump from a 5‑gallon pot to 1,500‑gallon tanks, the same WMS rules that worked for startup volumes will fail fast. The result: higher costs, shipment delays, regulatory risk, and painful recalls. This operational checklist shows exactly how to reconfigure your WMS and warehouse processes—drawn from food and beverage scaling scenarios—to keep costs down and traceability tight in 2026.

Why this matters now (2026 context)

By 2026, food and beverage buyers and regulators expect near‑real‑time traceability, tighter lot controls, and proof of cold chain integrity. Cloud WMS adoption has accelerated, AI forecasting is mainstream, and standards like GS1 Digital Link and EPCIS are widely implemented for supply‑chain visibility. Meanwhile, brands that scale quickly—like craft beverage makers shifting from artisanal batches to commercial tanks—face unique operational gaps in batching, lot traceability, and pick/pack flows. Fix them now to avoid recall costs, lost retail slots, and customer churn.

Topline actions: what to do first (inverted pyramid)

• Lock in master data: SKU, unit of measure, pack hierarchies, and ingredient BOMs.
• Define batch/lot granularity: Decide how you number and group production runs for traceability and picking.
• Configure lot control & expiry rules in your WMS for FEFO/FIFO and quarantine handling.
• Update pick/pack logic: Enable batch picking, mixed pallets, and split pick flows for DTC vs wholesale.
• Instrument traceability: Connect barcode/RFID labeling, EPCIS/GS1, and IoT sensors to the WMS for chain‑of‑custody data.

Operational checklist: 8 steps to prepare your WMS for SKU and batch growth

1) Discovery and master data cleanup (Week 0–2)

Before changing rules, ensure the data feeding those rules is accurate. This avoids cascading errors in picking and traceability.

1. Audit SKUs and packaging hierarchies. Merge duplicates, standardize UOMs (each, case, pallet), and assign parent/child relationships for flavor/size matrices.
2. Map Bill of Materials (BOM) for each beverage SKU: base syrup, water, preservatives, flavorings, co‑packing inputs. Store BOMs in ERP and mirror needed fields to WMS.
3. Tag each SKU with attributes: shelf life (open/closed), temperature class, allergen flags, regulatory notes, and recall priority.
4. Establish a single source of truth. Use middleware or an iPaaS to synchronize ERP, ecommerce, co‑packer systems, and WMS.

2) Decide your lot/batch strategy (Week 1–3)

Batching at scale changes the lot logic. Choose a strategy balancing traceability precision and operational simplicity.

• Batch = production run: Use when each tank is a unique recipe or processing date. Best for allergens or variant‑by‑batch products.
• Lot = fill event: Use when multiple fills occur from the same production batch but require unique serials (e.g., different label runs, canning lines).
• Hybrid: Keep a production batch ID and append a fill sequence to capture both lineage and handling events.

Action: Configure WMS to accept alpha‑numeric batch IDs, time stamps, and parent‑child lot linking. Implement automatic lot creation on GRN (goods receipt) from manufacturing output or co‑packer EDI/JSON feeds.

3) Configure lot control, expiry, and quarantine (Week 2–5)

Food and beverage demand strict FEFO/expiry rules and defined quarantine workflows.

1. Set expiration calculation rules in WMS based on production date + shelf life. Allow manual override with audit trail for re‑inspected lots.
2. Enable FEFO pick logic and automatic expiration alerts (30/14/7 days) for inventory managers and omnichannel picking flows.
3. Implement quarantine locations and statuses (e.g., TESTING, QUARANTINE, RELEASED). Configure inbound holds triggered by QC test results or supplier flags.
4. Design recall processes: search by ingredient/batch, bulk deallocation, and automated customer/retailer notification export. Test with a mock recall drill.

4) Rethink pick/pack flows: batching, wave, and split picking (Week 3–6)

When SKU counts spike and order types diversify (DTC single bottles vs wholesale pallets), pick logic must adapt to reduce touches and errors.

• Batch picking: Group multiple orders by SKU to reduce travel. Configure WMS to create batches that honor FEFO and lot constraints.
• Wave scheduling: Separate waves for time‑sensitive DTC orders, retailer pallets, and production replenishment. Align waves with carrier pickups.
• Split pick rules: Allow partial picks if a lot cannot fully satisfy demand, and automatically route backorders.
• Pick technology: Evaluate voice picking, pick‑to‑light for fast SKUs, and mobile barcode scanning for lot capture. Ensure devices support GS1 standards and EPCIS events.

5) Labeling, serialization, and traceability integration (Week 4–8)

Traceability is only as good as the data captured at each touchpoint. Standardize labels and integrate systems.

1. Standardize labels: include GTIN/UPC, batch/lot, production date, expiration, and, where required, GS1 Digital Link QR codes or serialized barcodes.
2. Integrate label printers (Zebra, SATO) with WMS to print at pack stations and during GRN. Ensure label templates include scannable trace data.
3. If using RFID, configure EPC numbering and ensure WMS captures tag reads and binds RFID IDs to lot numbers.
4. Connect WMS to traceability services (EPCIS or blockchain ledger) to publish events: raw material receipt, production, packaging, shipment.

6) Cold chain & IoT sensor integration (Week 4–10)

For many beverages, temperature integrity matters. Integrate IoT to capture and act on environmental data.

• Define temperature classes in WMS and assign to SKUs. Block picks for temperature‑sensitive SKUs unless shipping method meets requirements.
• Integrate real‑time sensor APIs (Teltonika, Sensitech, Monnit) to log warehouse AND trailer temperatures into WMS/TMS.
• Implement alert rules: immediate hold on temperature excursions, automatic creation of incident records, and retention of sensor data with lot history.

7) Test, train, and simulate (Week 6–12)

Configuration without realistic testing fails in live operations. Run end‑to‑end simulations with real SKUs and pick scenarios.

1. Run mock production receipts with large batch sizes and mixed fill events.
2. Simulate mixed orders: DTC single units, retail cases, and cross‑dock pallets. Validate pick consolidation and label output.
3. Conduct a recall drill: retrieve all impacted lots, generate reports for buyers, and run removal in WMS to measure throughput.
4. Train staff with new workflows, and create quick reference guides for packers and QA. Provide sandbox access for supervisors to practice exceptions and overrides.

8) Go‑live and continuous improvement (Week 9–ongoing)

Monitor KPIs closely after go‑live and iterate. Use the first 90 days as a rapid feedback window.

• Track KPIs: pick accuracy, orders per hour, on‑time shipping, traceability query time, and recall execution time.
• Set daily standups for the first 14 days post‑launch to resolve blockers and tune WMS rules.
• Plan quarterly audits of master data and lot policies as SKU complexity grows.

Configuration checklist: WMS settings you must review

Below are specific WMS settings and expected values or behaviors to review and test.

• Lot Granularity: Allow alpha numeric; parent batch + child fill suffix enabled.
• Expiry Logic: Production date + shelf life; FEFO enabled; expiration alerts at configurable thresholds.
• Quarantine Workflow: Location statuses, auto‑holds on failed QC, release workflows with digital signatures.
• Picking Strategy: Support batch, wave, zone, and split picks; respect lot rules during batch creation.
• Labeling API: Printer templates stored in WMS; GS1 Digital Link support; on‑demand label printing at pack.
• Traceability Events: Emit EPCIS events for key lifecycle actions; store event timestamps and device IDs.
• IoT Integration: Sensor event ingestion endpoint; excursion rules mapped to lot statuses.
• ERP/TMS Integration: Real‑time inventory sync, purchase orders, and ASN handling via API or EDI.

Pick/pack process changes to minimize cost and errors

Practical changes that operational teams can implement within days to reduce touchpoints and errors:

1. Consolidate fast‑moving flavor SKUs into forward pick faces and configure wave priorities accordingly.
2. Use batch pick for multi‑item small orders and separate pallet builds for wholesale to minimize staging time.
3. Introduce automated weight checks and dimensional scans at pack to catch miss‑packs and wrong lots.
4. Implement conditional pack rules: if an order contains both DTC and wholesale SKUs, split fulfillment by channel automatically.

Case example: Lessons from a craft beverage scale‑up

"We started with a pot on a stove and ended up with 1,500‑gallon tanks. The biggest blind spot was how we tracked each production run down to the bottle. Without lot discipline we risked shelf life errors and costly returns." — paraphrased from Liber & Co. founders' scaling story.

Key takeaways from craft beverage brands that scaled rapidly:

• Early investment in WMS lot control paid off. Capturing production batch IDs at line fill prevented manual rework later.
• Master data misalignment between manufacturing and distribution created pick errors. A single synchronized source fixed it.
• Simple label standardization (GTIN + lot + expiry) eliminated 60–80% of packing exceptions in pilot runs.

Technology stack recommendations (2026)

Choose tools that support scale and traceability without adding heavy integration costs.

• Cloud WMS with robust APIs and modular lot control (e.g., configurable events and recall utilities).
• Label & serialization software that supports GS1 Digital Link QR codes and batch serialization for co‑packers.
• EPCIS/traceability middleware to publish and query chain‑of‑custody events across partners.
• IoT platform with sensor integrations for temperature/humidity and automated alerts to WMS/TMS.
• AI forecasting to reduce safety stock while accounting for production lead times and seasonal surges.

KPIs and reports to monitor after changes

Track these daily during rollout and weekly after stabilization.

• Pick accuracy by lot and SKU
• Orders per hour by pick method (batch vs single)
• Time to resolve a failed traceability query
• Recall execution time (from trigger to inventory removed)
• Temperature excursion incidents per 1,000 pallets

Common pitfalls and how to avoid them

• Over‑granular lot IDs: Too much precision makes the system hard to use. Choose practical granularity—production batch + fill suffix balances traceability and usability.
• Ignoring pack hierarchies: Not modeling case/pallet/unit relationships causes wrong picks. Define pack types early.
• Not testing recalls: If you can't find and remove a batch in a drill, you can't during a real recall. Test quarterly.
• Undertraining: New workflows fail without clear SOPs and accessible reference material. Train with hands‑on sessions and roleplay exceptions.

Implementation timeline (recommended)

A pragmatic timeline to reconfigure WMS and processes without disrupting fulfillment:

• Weeks 0–2: Discovery, master data cleanup
• Weeks 1–4: Lot strategy and WMS configuration
• Weeks 3–6: Pick/pack workflow changes and labeling integration
• Weeks 4–8: IoT and traceability integrations
• Weeks 6–12: Testing, training, pilot go‑live
• Day 1–90 post‑go‑live: close monitoring and iterative tuning

Actionable takeaways (quick checklist)

• Audit and standardize SKU and BOM data this week.
• Decide on batch vs fill lot rules and configure WMS for parent/child lot IDs.
• Enable FEFO and expiration alerts; create quarantine workflows.
• Implement batch picking for small orders and dedicated pallet flows for wholesale.
• Integrate label printers and publish traceability events via EPCIS or GS1 Digital Link.
• Run a recall drill before retail ramp‑up; automate notifications and removals.
