OUR GOAL
To provide an A-to-Z e-commerce logistics solution that would complete Amazon fulfillment network in the European Union.
In today’s fast-moving e-commerce world, speed and accuracy in order fulfilment are critical competitive differentiators. As more consumers demand faster delivery, companies that can optimise their picking operations gain major advantages. For online retailers choosing a logistics partner like FLEX, streamlining the picking process is one of the fastest ways to improve customer satisfaction, reduce costs and scale sustainably.
This article will walk through the key aspects of efficient order picking in e-commerce, practical strategies you can apply, and how a provider like FLEX Logistique helps implement these strategies effectively.
Order Picking: The Silent Engine Behind Every Fast Delivery
Order picking – the process of selecting items from storage to fulfil customers’ orders – is often one of the most labour- and cost-intensive parts of warehouse operations. According to academic research, it constitutes a substantial portion of total warehouse operating costs.
In the French e-commerce market:
82 % of French consumers say delivery time influences their choice of company.
Only about 50 % of e-tailers were able to dispatch orders the same day.
In a 2024 logistics market report, average transit time for domestic shipments in France was reduced to 1.85 days, with an on-time ratio of 93%.
These figures highlight three key take-aways:
Time is critical: The faster you pick and dispatch, the more you meet customer expectations.
Accuracy matters: Mistakes or inefficiencies in picking ripple through to returns, customer dissatisfaction and cost increases.
Location and process matter: With the right warehouse, layout and logistics partner you’re positioned to win.
For a company like FLEX Logistique – with strategic warehouse locations (e.g., northern France: Épinoy-Cambrai) and e-commerce fulfilment focus – optimising order picking becomes a core service offering.
Key Elements of Efficient Order Picking in E-Commerce
To optimise order picking and speed up e-commerce fulfilment, several interconnected components must work together — from warehouse layout to technology and team performance. Here’s how each part contributes to faster, smarter logistics.
Optimising Warehouse Layout for Faster Fulfilment
A well-designed warehouse is the foundation of efficient order picking. The physical arrangement of goods directly impacts picker travel time, congestion, accessibility, and overall productivity.
Best practices include:
Slotting high-velocity SKUs (stock-keeping units) closer to packing and dispatch zones.
Using shelving, mezzanine, or flow-rack systems aligned with picking flow.
Minimising picker travel distance with intelligent zoning and storage logic.
Adopting flexible storage policies (dedicated vs. random) to balance efficiency and adaptability.
With class A warehouses strategically located across France, Poland, Germany, and the UK, FLEX Logistique builds layouts designed for maximum efficiency and minimal handling time — ensuring faster fulfilment for e-commerce clients.
Smarter Order Batching and Picker Routing for Speed and Accuracy
Grouping and sequencing orders effectively can reduce unnecessary walking, idle time, and congestion — boosting productivity by up to 15%.
Key optimisation tactics:
Batch orders by product type, zone, or shipping priority.
Design picker routes that avoid back-tracking.
Use a Warehouse Management System (WMS) to calculate optimal routes in real time.
Track KPIs like picks per hour (PPH), travel time, and accuracy to fine-tune performance.
FLEX leverages advanced WMS tools to dynamically route pickers and manage workflows — helping e-commerce brands reduce cost per order and accelerate delivery.
Choosing the Right Order Picking Strategy for Your Business
Every e-commerce operation has unique needs based on order size, SKU diversity, and fulfilment volume. Selecting the right picking method ensures optimal balance between speed, cost, and accuracy.
Common strategies include:
Single-order picking – simple, accurate, best for low-volume or high-value orders.
Batch picking – multiple orders in one route; boosts efficiency for repetitive SKUs.
Wave picking – releases orders in waves, ideal for large-scale operations.
Zone or cluster picking – divides the warehouse into sections handled by specialists.
FLEX’s logistics experts analyse each client’s order patterns to implement the most efficient picking strategy — ensuring scalability and precision as volumes grow.
Leveraging Warehouse Technology and Automation to Boost Performance
Technology is now central to modern warehouse efficiency. Automation tools and digital workflows not only accelerate picking speed but also enhance accuracy and traceability.
Top technologies driving optimisation:
Pick-to-light and put-to-light systems
Voice-directed picking
Mobile scanning and barcode verification
Automated storage and retrieval systems (ASRS) and robotics
Even for mid-sized operations, implementing a real-time WMS can significantly improve fulfilment metrics. In fact, 70% of logistics companies now prioritise order-picking improvement as a key investment area.
FLEX Logistique integrates with major e-commerce platforms and provides real-time visibility over inventory and orders, ensuring flawless coordination between technology and human workflow.
Building a Skilled, Motivated Picking Workforce
Technology alone doesn’t guarantee efficiency — people do. A trained, motivated workforce is essential to maintaining speed, accuracy, and quality, especially during peak seasons.
Best practices for workforce optimisation:
Regular training on SOPs and picking tools.
Ergonomic workstation design to reduce fatigue.
Performance monitoring (PPH, accuracy, idle time).
Incentives for top performance and quality metrics.
At FLEX, workforce management is central to operations. Well-trained teams ensure that every order is picked, packed, and shipped with precision — no matter the volume.
Continuous Improvement Through Data-Driven Warehouse Analytics
Order picking isn’t a one-time optimisation project — it’s an ongoing process powered by data. Continuous performance tracking helps identify bottlenecks and unlock further gains.
Essential metrics to track:
Picks per hour (PPH) or lines per hour (LPH)
Average travel time per pick
Order accuracy and error rates
Cost per order or per pick
On-time dispatch rate
By benchmarking these KPIs regularly, FLEX continuously refines its processes — ensuring long-term efficiency and competitive advantage for its e-commerce clients.
Practical strategies for faster e-commerce fulfilment
Here are specific strategies you can implement (or ask your 3PL partner to implement) to achieve faster order picking and fulfilment.
Strategy 1: Prioritise fast-moving SKUs
Identify your top 20 % SKUs in terms of order volume (Pareto principle suggests this may cover ~80% of picks) and reposition them in the most accessible locations. Doing so reduces picker travel and speeds up fulfilment of the bulk of orders. You might also group related SKUs together when they are frequently ordered together.
Strategy 2: Use dynamic slotting
Rather than a static storage policy, use dynamic slotting so that high-volume items move to the front zones, and lower-volume or seasonal items occupy slower access zones. This ensures the picking area remains optimised as order patterns shift.
Strategy 3: Implement batch picking during lull times
If order arrivals allow, batch pick across multiple orders during off-peak periods, then consolidate and dispatch. This reduces the number of picker “walks” through the warehouse. For higher order volumes, wave picking may be more appropriate.
Strategy 4: Real-time order routing
As orders arrive, especially in flash-sale or dynamic inventory situations, real-time routing of pickers via WMS ensures that pickers pick in logical sequence with minimal idle/travel time. This is especially helpful when a 3PL like FLEX is handling multiple clients and varying order volumes.
Strategy 5: Zone and cluster picking for complexity
If you have high SKU diversity and multi-line orders, divide the warehouse into zones or clusters. Assign pickers to zones and consolidate at pack-out. This reduces congestion, improves focus, and allows speed in each zone.
Strategy 6: Use pick-to-light / scanning / automation where cost-effective
While full robotics may not be feasible for all operations, mobile scanning, barcode verification, or pick-to-light systems can still dramatically boost accuracy and speed. Even moderate automation can reduce error rates and re-work.
Strategy 7: Align warehouse operations with last-mile delivery targets
Knowing that in France the average domestic transit time has dropped to 1.85 days, you must ensure that your picking and dispatch processes support rapid shipment. Work backwards from your desired delivery promise (e.g., 24-48 h) to set internal picking targets accordingly.
Strategy 8: Leverage the strategic location of your logistics partner
Since FLEX’s French warehouse is located at Épinoy-Cambrai in the north of France, just about 1 hour from the major Amazon FC CDG7 in Senlis and ~2 hrs from major container ports like Le Havre, it offers fast inbound and outbound flows. Use this locational advantage to shorten picking-to-dispatch lead-time.
Strategy 9: Monitor KPIs frequently and iterate
Establish a dashboard for order picking: picks/hour, travel time, error rate, dispatch lead time, cost per order. Review weekly, and run root-cause analysis on under-performance, then implement corrective action (e.g., retraining, layout tweak, batch policy change).
Strategy 10: Plan for peak seasons and returns
E-commerce peaks (e.g., Black Friday, Christmas) bring surges in order volume and returns. Ensure your pick-pack team has surge capacity, flexible staffing, and pre-itinerary layout adjustments. With returns integration potentially adding inefficiencies, research shows cost-savings of 10-15% when returns handling is integrated into picking efficiently. FLEX’s fulfilment offering includes return management, which means picking optimisation should incorporate the full return/dispatch cycle.

Real-World Success Scenario: How FLEX Transforms E-Commerce Fulfilment
To see the real impact of optimised order picking, let’s look at a typical mid-sized e-commerce brand partnering with FLEX Logistique for fulfilment in France.
The challenge:
A growing online retailer handling around 10,000 monthly orders and managing 300 SKUs was struggling to keep pace with demand. Their existing process involved long walking routes, inconsistent batch picking, and limited use of warehouse data. On average, each picker completed 40 order lines per hour, with a 2.5 % error rate and 36-hour dispatch times — slowing customer deliveries and straining margins.
The FLEX approach:
FLEX’s fulfilment specialists conducted a full operational audit, then implemented a three-step optimisation plan:
Re-slotting inventory: The top-selling 20 % of SKUs were relocated closer to the packing zone, cutting picker travel time.
Smart batching and routing: FLEX’s WMS dynamically grouped similar orders and calculated the shortest picking paths.
Performance tracking: Real-time dashboards monitored picks per hour and accuracy to maintain momentum.
The results:
Within weeks, efficiency skyrocketed:
Travel time per pick: Reduced from 45 s to 30 s
Picks per hour: Increased from 40 → 60 lines
Error rate: Dropped to 1 %
Average dispatch time: Cut from 36 h → 24 h
The outcome:
Customers received orders faster, satisfaction scores improved, and repeat purchases grew. The retailer also reduced operational costs by double-digit percentages — without expanding its workforce.
With FLEX’s scalable warehouse network, data-driven routing, and expertise in e-commerce logistics, such performance gains are not hypothetical — they’re what smart fulfilment looks like in action.
