Pick-to-Tote – Technology for Modern Goods-to-Person Warehouses

As a manufacturer and integrator of automated warehouse systems, KAPELOU analyzes your order structure, warehouse topology, and implements Pick-to-Tote to optimize the picking zone, increase order picking speed, and reduce the workload on people.

Let’s look at how implementing Pick-to-Tote technology in intralogistics can work for your competitive advantages.

How Pick-to-Tote Technology works: 4-Step Goods-to-Person Workflow

Pick-to-Tote is a step towards realizing the Goods-to-Person concept: automation is responsible for moving cargo in boxes, and operators work without unnecessary walking between warehouse racking.

How Pick-to-Tote Works:

1. Initiation: WMS reads the barcode or RFID tag of the plastic tote or the box and links a unique order to it.
2. Transportation: the conveyor delivers the plastic tote or the box only to those zones where the required item is located. It bypasses other zones.
3. Zoned item picking: the diverter directs the plastic tote or the box to a conveyor spur. The operator sees a prompt on the screen – what and how much to take from the shelf and put into the tote.
4. Control and Packing: the operator returns the plastic tote or the box to the line, which moves it to the next zone or directly to final packing and weight control.

To understand the efficiency of Pick-to-Tote, let’s compare this technology with other common picking methods:

• Pick-to-Tote (into a plastic tote): maximum protection for small and fragile goods. Totes or plastic boxes are operated for years without changing shape;
• Pick-to-Carton (into a carton box): the item is picked from racking directly into customer packaging, but cardboard wears out in one cycle and can deform on the conveyor due to weight;
• Pick-to-Belt (onto a moving conveyor belt): applied for intensive movement of large volumes of small-piece products and items without individual packaging. Requires special design (modified sealed sides) for reliable cargo retention during movement and precise line speed synchronization for further order processing;
• Pick-to-Cart (into a trolley): classic manual picking. The operator pushes the trolley, picking goods from racking according to a paper invoice.

KAPELOU integrates Pick-to-Tote into warehouse logistics, combining automated equipment and software into a single system:

• conveyors: warehouse automation provides smooth and fast movement of plastic totes or boxes without collisions and damage;
• shuttle systems and Miniload: automatically retrieve boxes from high-density racking and feed them to the conveyor;
• AS/RS GNOM: mobile robots buffer up to 16 plastic totes or boxes with picked goods simultaneously and deliver them to operators;
• A-Frame: vertical dispensers issue small-piece goods into totes, trays or plastic boxes with a capacity of up to 3,000 orders/hour;
• Pick-by-Light and Put-to-Light: warehouse technologies that use light indicators to guide operators to the correct racking cell for picking and the target plastic tote, tray or box for putaway;
• industrial robot manipulators: tote picking with a capacity of up to 500 items/hour is based on the algorithm: 3D scanning (machine vision analyzes goods), gripping (software builds trajectory, manipulator fixes item with special grippers), weight verification (reconciliation of parameters with WMS tolerances), placement (robot adapts release height to plastic tote, tray or box fill level);
• pharmacy robots: lights-out tote picking automation for slow- and medium-mover pharma products.

7 Main Advantages of Pick-to-Tote for Business and ROI

Automating picking from racking straight into plastic totes or trays directly boosts Return on Investment (ROI) due to main factors:

• higher picking speed: with the Goods-to-Person picking system, operators eliminate unnecessary travel time between racking rows – the goods are delivered to them automatically. Warehouse automation increases tote picking productivity several times;
• accuracy over 99.9%: warehouse tote picking automation due to a conveyor with barcode scanners, Pick-by-Light racking navigation, and weight control systems reduces the impact of the human factor;
• scalability: if order volumes double due to seasonal peaks, the warehouse does not need to be rebuilt. Simply extend conveyor lines and racking, add tote picking zones, and introduce additional plastic totes, trays or boxes;
• cargo protection: a rigid plastic tote, tray or box is a reliable protective container. Items inside are protected from deformation, which is important for e-commerce, pharmaceutical, and cosmetics logistics;
• material flow control: each tote, tray or plastic box has a unique barcode or RFID tag. The WMS/WCS software tracks exact racking locations for orders and monitors zone workload in real time;
• warehouse space saving: modern warehouse technologies enable the integration of lines with automated storage systems, racking, or mezzanines, significantly increasing warehouse capacity;
• warehouse logistics stability without staff shortage: dependence on the specific experience of certain operators disappears.

Tote Picking in Detail: KAPELOU Case Study for a Pharma Distributor’s Warehouse Logistics

Modern warehouse logistics increasingly combines automated and manual processes, adhering to the rule: the order is formed in one tote, which automatically passes all picking stages.

The KAPELOU team applied the tote picking approach to automate warehouse logistics for a national pharmaceutical distributor in Saudi Arabia. Project goal: increase dispatch speed, eliminate picking errors, ensure expiration date control, and real-time inventory tracking.

At the heart of the solution is a mixed tote picking system. The conveyor system sequentially transports totes through three specific tote picking zones depending on the demand profile of the goods:

• Zone 1: semi-automated tote-based picking system (high turnover). The operator scans the order barcode, and the system displays accurate prompts on the screen and controls the tote picking correctness. After confirmation, the plastic tote automatically moves further;
• Zone 2: full automation of tote picking (low and medium turnover). Order picking with a large number of small SKUs is carried out by BD Rowa™ robotic dispensers. The robot independently finds the required item and places it directly into the plastic tote, completely eliminating manual search;
• Zone 3: manual picking of bulky orders. Assembling large packages is done manually, but integrated into the overall order flow without disrupting line logic. After completing the route, each plastic tote automatically enters the weight control and final check zone.

Thanks to the synergy of Goods-to-Person processes, plastic tote picking automation, and robotization of complex zones, the pharmaceutical distributor received the following business metrics:

• warehouse throughput increased by 50%;
• need for operators reduced by 60%;
• number of manual operations and additional product movements minimized.

Challenges of Implementing Pick-to-Tote (G2P Picking) and Ways to Overcome Them

Despite the obvious advantages of Pick-to-Tote, its implementation requires careful planning of warehouse processes. Most often, problems arise due to discrepancy between tote picking logic and actual structure of goods flows.

1. Incorrect SKU Segmentation
One of the most common mistakes is using the same tote picking scenario for all goods. In practice, low-turnover items, popular SKUs, and bulky products have different requirements for order picking speed, storage, and transportation in totes, trays and boxes.
Solution: applying a hybrid order picking model, where the optimal tote picking technology is used for each product group.

2. Imbalance Between Tote Picking Zones
In multi-zone warehouse logistics, different tote picking areas can work at different speeds.
Solution: using conveyor buffers allows maintaining continuous movement of orders in plastic boxes, trays and totes under uneven load.

3. Tote Picking Integration with Existing Warehouse WMS
Pick-to-Tote efficiency directly depends on data quality. Inaccurate information about warehouse balances, storage locations, or order status can lead to tote picking errors and reduced productivity.
Solution: full integration of tote picking zones and automated systems with WMS or WCS. The system tracks the location of each plastic tote, box or tray, order status, and real-time inventory availability across the warehouse racking.

4. Growth in the Number of SKUs
With range expansion, the number of movements increases, inventory management becomes more complicated, and workload on operators grows.
Solution: implementing automated storage and picking systems allows working with a large number of SKUs without a proportional increase in warehouse space and number of operators.

5. Initial Investment and Justifying ROI of Pick-to-Tote
Pick-to-Tote warehouse technology requires investment not only in conveyor equipment, but also in software, integration with WMS/WCS. For many companies, the main challenge is calculating the economic effect of the tote picking.
Solution: evaluate the tote picking by the overall impact of Pick-to-Tote implementation on warehouse logistics efficiency – increasing productivity, reducing errors, reducing operator requirements, optimizing warehouse space, and scalability without a proportional increase in resources.

6. Adapting Operators to New Tote Picking with Pick-to-Tote Implementation
The transition from traditional manual order picking to automated assembly from racking into plastic boxes or trays on the Pick-to-Tote principle changes the operator’s role. The employee no longer spends time searching for goods, but picks orders within a controlled process, interacting with WMS, scanners, Pick-to-Light systems, or automated workstations.
Solution: involve staff in the project already at the Pick-to-Tote implementation stage, conduct training on real tote picking scenarios, and gradually transfer the warehouse to a new order assembly process. Practice shows that after adaptation, operators reach higher productivity faster, and dependence on individual experience of specific employees drops significantly.

Pick-to-Tote: when Speed, Accuracy, and Scalability Become a Competitive Advantage

The earlier a warehouse starts working smoothly, the easier it is to scale operations without losing speed and service quality. Pick-to-Tote allows reducing non-productive operator movements and ensuring control over every stage of assembling orders into a plastic box or tray. Automated order fulfillment with tote picking turns chaotic manual processes into transparent, predictable, and highly productive warehouse logistics.
