Is FIFO always better than LIFO?

No. LIFO can make sense in specific cases: storage of non-perishable, homogeneous materials (sand, aggregates), or when accounting considerations outweigh operational requirements. But in transformation industries with dated or traced references, FIFO is almost always the right rule.

How much does FIFO deployment cost on a zone?

Highly variable depending on volumes and support type. As an indication, a full FIFO deployment on a 100 to 200 m² storage zone (dynamic flow racks + marking + labeling + training) sits between €15,000 and €60,000. ROI is typically reached in 6 to 18 months on the reduction of expiry losses alone.

Do you need an ERP or WMS to manage FIFO?

Not necessarily. For simple storage zones, physical FIFO with manual labeling is enough in 80% of cases. ERP or WMS become useful when volumes grow (thousands of references), when documentary traceability is regulatory (pharma, aerospace), or to pilot multiple sites remotely. Pitfall: believing that a digital system replaces physical FIFO. Without physical support, the rule isn't held.

What's the difference between FIFO and FEFO?

FIFO (First In, First Out): you ship in entry order. FEFO (First Expired, First Out): you ship in expiry-date order. When lots arrive in production-chronological order, FIFO and FEFO are identical. But if a more recent lot has a shorter shelf life (e.g. close to production), FEFO is preferable. In practice, many sites implement "FIFO+FEFO": FIFO by default, FEFO when expiry dates differ between lots.

Is FIFO compatible with a Kanban system?

Not only compatible — strongly recommended. Kanban regulates flows, FIFO controls rotation. The two work together: Kanban on non-FIFO stock quickly becomes problematic because sizing relies on rotation times you don't control. Conversely, the Kanban + FIFO pair is among the most effective in Lean.

How long does it take to deploy FIFO on a zone?

From 4 to 12 weeks depending on complexity. For a simple zone with modular dynamic flow racks and standard labeling, count 4 to 6 weeks (including 1 week of effective installation). For a complex zone with hygiene/ESD/GMP constraints, design and validation can push the timeline to 10-12 weeks.

Should you do a baseline audit before starting?

Yes, and it's often the most instructive step. The pre-inventory systematically reveals dormant or expired stock no one suspected. Better to discover this internally before rolling out FIFO than during a customer audit. The baseline also conditions the right sizing of the physical supports.

FIFO method: the controlled rotation that eliminates your losses

A pallet sleeping for 6 months while another, more recent one goes into production. An expired lot discovered too late. Aged components mixed with new ones. FIFO (first in, first out) wipes out these drifts with a simple discipline — but one that demands the right physical supports.

FIFO or LIFO: the rule that determines your losses

Every storage area follows one of these two rules, knowingly or by default. Understanding the difference and choosing the right one is the first step toward healthy stock management.

Comparison diagrams of FIFO vs LIFO by Makitlean

Storage area before and after FIFO implementation

LIFO: by default

Last In, First Out

The last arrived leaves first. The default when stacking without thinking: you grab what's in front, on top, easiest to reach.

Old lots sleeping at the back for months
Expired shelf lives undetected
Aged components (pharma, electronics, seals)
Degraded traceability (mixing between deliveries)
Direct financial losses on unusable products

FIFO: the method

First In, First Out

The first arrived leaves first. Tunnel logic: in at the back, out at the front. Guarantees chronological lot flow with no human intervention.

Automatic chronological rotation
Shelf lives respected with no cognitive effort
Controlled age for sensitive components
Per-lot traceability preserved

FIFO or LIFO: see the difference in motion

Add and remove lots, run the automatic demo and adjust the expiry duration. You'll see why LIFO traps old lots at the back, where FIFO rotates stock in order.

LIFO: by default

Last in, first out

The last in is the first out. Old lots stay buried at the bottom of the stack.

What a workshop without FIFO costs

The absence of FIFO produces diffuse losses, rarely accounted for as such. Here are the 6 angles where those losses show up on the industrial sites we work with.

Expiry losses

Lots scrapped at the end of the line for expired shelf life. In food & beverage this typically represents 0.5 to 3% of materials revenue, an item rarely isolated in management accounting.

Regulatory non-compliance

In pharma, food and aerospace, failure to follow FIFO can lead to a failed customer audit, loss of certification (BRC, IFS, IATF, GMP), even product recall.

Component aging

Seals, adhesives, batteries, ESD components: their shelf life starts at production, not at use. Without FIFO, you regularly assemble aged components that fail prematurely.

Degraded traceability

Mixed lots = downstream traceability impossible to reconstruct. In case of customer complaint or recall, you no longer know which finished products contain which component lot.

Inaccurate inventories

When the actual age of stock no longer matches its ERP entry date, inventories become unreliable. Direct consequence: purchasing decisions based on bad data.

Roadblock to a future Kanban

Without controlled FIFO, it's impossible to set up a robust Kanban system: sizing relies on rotation times you don't control.

The least expected immediate effect: simply rolling out FIFO reveals stocks whose real age was unknown. Many sites discover 5 to 15% of their stock already expired or out of spec — a topic better discovered with the FIFO method than during a customer audit.

Setting up an effective FIFO in 4 steps

FIFO is not just a poster instruction. It's a combination of physical (supports), marking (labels) and discipline (rituals). Here is the sequence that works.

Identify the zones where FIFO is critical

Not every storage area requires strict FIFO. Prioritize references with shelf life (expiry dates), components with limited lifespan (seals, adhesives, batteries), and anything subject to customer or regulatory per-lot traceability.

Prioritization criterion: cost of loss × frequency of occurrence. A €50 component that expires once a year is less of a priority than a €5 component that expires once a month.

Dynamic flow racks that adapt to your references

Your references evolve: new packaging, new formats, changing volumes. If your FIFO racks are rigid (welded shelves, fixed dimensions), each change costs a new project. Our modular tubular structures let FIFO breathe. From dynamic flow rack to gravity conveyor, every support reconfigures with no special tooling.

Gravity dynamic flow racks

Inclined roller shelves that ensure automatic FIFO rotation: loading at the back, picking at the front. The oldest bin naturally arrives at the picking position.

Floor FIFO lanes for pallets

Marking and signage of FIFO lanes for floor-stored pallets. Traffic direction, entry and exit positions clearly identified. Suited to high-volume, low-rotation references.

Sequenced bins and color labeling

Small-parts solutions with color-coded bin management (green/yellow/red by age). Immediate visual identification of priority lots, no need to read each label individually.

Visual lot tracking boards

Visual management boards built into the FIFO zone: current lots displayed, entry dates, status, expiry alerts. Combines operational pilot and documentary traceability.

Educational illustration of a Makitlean FIFO tunnel

The MKL advantage: when your packaging evolves (new bin, new pallet, new format), your dynamic flow rack reconfigures in a few hours by an in-house operator. No quote, no waiting, no zone stop. A condition often overlooked but decisive for FIFO longevity.

To last over time, FIFO rests on a 5S method that structures the space and a visual management that makes lot age immediately legible.

FIFO by your industry

The rule is universal, its stakes vary. Here is how FIFO applies to the five industrial sectors we work with.

Food & beverage

Shelf life, IFS/BRC traceability

FIFO is non-negotiable: customer requirement, IFS and BRC certifications, veterinary inspections. Applied to ingredients, food packaging, semi-finished goods. Supports compatible with bio-cleaning and humid environments.

Pharma & cosmetics

GMP, lot release, recalls

FIFO mandatory in GMP environments: raw materials, packaging items, semi-finished goods. Strict per-lot labeling with entry date, quality status and reception number. Documentary support for regulatory audits.

Aerospace

Life-limited components

Critical application on seals, adhesives, sealants, paints: all components whose lifespan begins at production. Per-unit or per-lot traceability required by EASA and FAA prime contractors.

Automotive & suppliers

IATF, per-lot traceability

FIFO on assembled, electronic and elastomer components. Per-lot traceability conditions the ability to isolate a quality defect, a topic directly addressed by IATF 16949 audits and PPAP requirements.

Electronics & high-tech

MSL, ESD, programmed components

FIFO on Moisture Sensitive Level (MSL) components, programmed SMD, batteries. Uncontrolled aging leads to higher in-production defect rates. ESD bins and specific labeling required.

Mechanical & subcontracting

Buffer stocks, WIP

Even outside regulatory requirements, FIFO on machining and transformation WIP simplifies management: less confusion between batches, quick identification of quality drift, preparation for customer audits.
