What Is Warehouse Automation?
Warehouse automation is the process of automating the movement of inventory into, within, and out of warehouses to customers with minimal human assistance. As part of an automation project, a business can eliminate labor-intensive duties that involve repetitive physical work and manual data entry and analysis.

For example, a warehouse worker may load an autonomous mobile robot with heavy packages. The robot moves the inventory from one end of the warehouse to the shipping zone and software records the movement of that inventory, keeping all records current. These robots improve the efficiency, speed, reliability and accuracy of this task.

But warehouse automation does not require physical or robotic automation, and in many cases simply refers to the use of software to replace manual tasks. However, this scenario illustrates how robots and humans work together to accomplish repetitive tasks while minimizing fatigue and injury.

Categories of Warehouse Automation Explained
Warehouse automation varies from relatively simple to quite complex. Basic automation uses planning, machinery and vehicles to reduce repetitive tasks. Advanced systems take advantage of artificial intelligence and robotics.

Warehouse automation categories include:
Basic Warehouse Automation: This type of automation refers to simple technology that assists people with tasks that would otherwise require more manual labor. For example, a conveyor or carousel moves inventory from point A to point B.
Warehouse System Automation: This type of system uses software, machine learning, robotics and data analytics to automate tasks and procedures. For example, a warehouse management system reviews all the orders that need to be filled in a day and has users pick like items to fulfill all those orders at once so they don’t traverse the warehouse back and forth multiple times.
Mechanized Warehouse Automation: This kind of warehouse automation uses robotic equipment and systems to assist humans with warehouse tasks and procedures. Autonomous mobile shelf loader robots that lift racks of products and deliver them to human pickers to retrieve and sort is one example.
Advanced Warehouse Automation: Advanced warehouse automation combines mechanized warehouse robotics and automation systems that can replace labor-intensive human workflows. For example, a robotic forklift fleet that uses advanced AI, cameras and sensors to navigate a warehouse and communicate each forklift’s location to an online tracking portal.
Types of Warehouse Automation Technology
There are many types of warehouse automation because there is a wide range of warehouse technology and systems available. Warehouse automation aims to minimize manual tasks and speed up processes, from receiving to shipping.

Warehouse automation technology includes:
Goods-to-Person (GTP): Goods-to-person fulfillment is one of the most popular methods for increasing efficiency and reducing congestion. This category includes conveyors, carousels and vertical lift systems. When properly applied, GTP systems can double or triple the speed of warehouse picking.
Automated Storage and Retrieval Systems (AS/RS): AS/RS are a form of GTP fulfillment technology that includes automated systems and equipment like material-carrying vehicles, tote shuttles and mini-loaders to store and retrieve materials or products. High-volume warehouse applications with space constraints tend to utilize AS/RS systems.
Automatic Guided Vehicles (AGVs): This class of mechanized automation has minimal onboard computing power. These vehicles use magnetic strips, wires or sensors to navigate a fixed path through the warehouse. AGVs are limited to large, simple warehouse environments designed with this navigation layout. Complex warehouses with lots of human traffic and space constraints are not good candidates for AGVs.
Autonomous Mobile Robots (AMRs): More flexible than AGVs, AMRs use GPS systems to create effective routes through a specific warehouse. They use advanced laser guidance systems to detect obstacles, so AMRs can safely navigate dynamic environments with lots of human traffic. They are easy to program with routes and easy to implement quickly.
Pick-to-Light and Put-to-Light Systems: These systems use mobile barcode scanning devices synced to digital light displays to direct warehouse pickers where to place or pick up selected items. They can dramatically reduce walking and searching time and human error in high-volume situations.
Voice Picking and Tasking: The use of voice-directed warehouse procedures, also known as pick-by-voice, uses speech recognition software and mobile headsets. The system creates optimized pick paths to direct warehouse workers where to pick or put away a product. This method eliminates the need for handheld devices like RF scanners, so pickers can concentrate on their task with improved safety and efficiency.
Automated Sortation Systems: Sortation is the process of identifying items on a conveyor system and diverting them to a warehouse location using RFID, barcode scanners and sensors. Companies use automated sortation systems in order fulfillment for receiving, picking, packing and shipping.

When to Automate Your Warehouse
Deciding when to automate your warehouse depends on a host of factors. You’ll need to evaluate your processes and procedures, examine your supply chain, recruit in-house expertise and identify gaps in current technology and future business goals.

8 Questions to Decide If It’s Time to Automate Your Warehouse
Answer these questions before committing to warehouse automation projects:

Are your customer orders delayed due to a limited workforce?
Are your existing warehouse processes and procedures labor-intensive?
Is your order fulfillment capacity declining?
Are your inventory counts inaccurate?
Are you still using legacy warehouse management software or manual inventory management tools like spreadsheets?
Is customer satisfaction data indicating problems in the supply chain?
Do you have to increase/decrease your workforce to meet fluctuating demand?
Do you have buy-in from key stakeholders?
How to Automate Your Warehouse
Automating a warehouse requires a project plan. You’ll need to involve stakeholders, create a project schedule, complete a risk assessment and designate goals and deliverables.

First, form a support team and designate project manager(s). They will determine a project schedule and build a timeline and deliverables calendar. Next, make implementation support plans with feedback from all levels of management (including corporate leadership and warehouse managers from all locations). Finally, choose the warehouse automation that best supports your business goals, customer demand, and incorporates feedback from your team, time and available resources. When reviewing automation options, you’ll need to research these options and request demonstrations. Implementing mobile barcode scanning has different requirements than installing an AS/RS inventory management system, for instance.

5 Steps to Automate Your Warehouse
Use this sample five-step plan to get started with warehouse automation.

Create an implementation committee.
Form a committee of internal stakeholders who have expertise on current warehouse performance, capabilities and challenges, and understand existing technology gaps. Consider adding third-party experts who know about supply chain automation and have experience relative to your industry and warehouse operations.
Collect critical data.
Successful warehouse automation relies on data about your existing supply chain and business-critical warehouse operations. Before implementing new automation technology, evaluate your current data collection process and infrastructure. You’ll want to assign ownership of data migration to skilled IT stakeholders.
Evaluate your inventory controls.
Inventory control is at the core of warehouse operations. Before implementing a warehouse automation solution, determine or refine your standard operating procedures (SOPs) for inventory control. Include SOPs for purchasing, shipping, receiving, customer satisfaction and inventory loss. Define the key performance indicators (KPIs) to measure the success of automated inventory control processes and procedures. Evaluate the inventory accounting method currently in place (for example, periodic or perpetual systems) and determine how automation will impact it. Read the guide about inventory control to learn more.
Implement a warehouse management system (WMS).
WMS platforms feature software modules that help control and track inventory, manage warehouse operations, reduce labor costs associated with manual tasks, and improve customer service. A modern WMS supports mobile devices and should be able to work with your existing enterprise software.
Determine what kind of warehouse automation you want.
Is your goal to use automation to streamline manual data entry and reduce labor costs associated with back-office warehouse operations and accounting? Or, are you expanding your warehouse footprint or adding locations and think it’s time to use advanced physical process automation like robots and GTP systems? Determining the type of warehouse automation that aligns with goals and customer demand is essential.

To minimize maintenance issues, you’ll want to set up maintenance schedules. Consider contracting with a third-party vendor that provides skilled maintenance and repair experts to ensure the new systems and equipment stay operational. The high upfront costs for equipment and setup typically pay for themselves over time through efficiencies and increased sales, but businesses need to carefully anticipate and mitigate some challenges with proper risk assessment and planning. The planning phase should include regular inventory audits to verify the accuracy of new data from automated processing against existing records. See below for more details on how much it costs to automate your warehouse.

Warehouse Automation Best Practices
The warehouse’s role in the supply chain has evolved significantly. Modern warehouses provide business-critical, cost-saving functions and add value to customer experiences.

Here’s a list of six warehouse automation best practices to consider:
Integrate with a WMS: Make sure the warehouse automation systems you choose integrate with a WMS platform. Look for a solution that can manage inventory controls, track inventory, monitor and report on labor costs, integrate dashboards and automates these capabilities. Learn more about WMS features and the difference between inventory management and warehouse management.
Invest in Scalable Solutions: Your technology should scale with your business. The system should account for adding future warehouses, employees, equipment and new supply chain partnerships, like 3PLs or drop shippers.
Automate Data Collection: Regardless of the type and level of warehouse automation, you're considering long term, start with a solution that automates data collection, transfer and storage. Cloud-based solutions paired with mobile barcode scanners create a low-cost, low-risk path to automation. This ecosystem will help you eliminate human error, capture critical warehouse performance and inventory data, and store it in a centralized cloud database for further analysis.
Perform Continuous Cycle Counts: Cycle counts monitor inventory levels against the inventory data record and are a key feature of WMS. Once you have automated data collection systems in places, you can automate continuous cycle counts with mobile barcode scanning or RFID sensors. Then you can use dashboards to check for inventory discrepancies.
Optimize Receiving: Warehouse data collection starts with receiving, so you want a system that can collect as much data as possible upfront to help direct warehouse workflows. Identify the incoming product (dimensions, classifications, packaging), then set rules in your WMS that determine how to handle it, where to store it and how to direct available resources to put it away.
Evaluate Warehouse Design: Many physical automation solutions, including GTP and AS/RS systems, AGVs and sortation systems, require specific warehouse layouts and ample space to be successful. Consider reworking the design of existing warehouses and distribution centers to optimize them for automation technology. Work with solutions vendors, architects and contractors that understand your unique requirements. You’ll want to include this evaluation in your implementation budget.
What Warehouse Processes Can Be Automated
Many warehouse processes can be automated, such as bin tracking, cycle counting and order picking. Warehouse process automation leads to more cost-effective operations and reduces product handling costs.

Warehouse Processes that Benefit from Automation
Warehouse Process Automation
The right warehouse automation technology can automate tasks that touch every aspect of order fulfillment and inventory control, including:

Receiving: You can use mobile devices to quickly capture data in your warehouse’s receiving area. Integrated software captures, processes and stores data that impacts downstream and upstream automated workflows.
Returns: Automated sorting systems and equipment like conveyors can automate return processing procedures. Use them to sort products to return-to-stock shelves or put away in designated storage locations.
Putaway: Putaway refers to the act of moving products from receiving to storage. Physical and digital warehouse process automation can make putaway more efficient and accurate. Automating this process can also help facilitate cross-docking, where goods are rapidly sorted, processed and placed onto trucks bound for different destinations instead of being stored in the warehouse.
Picking: Manual order picking is the costliest warehouse activity—warehouse travel time can consume as much as 50% percent of working hours. Using GTP systems and autonomous mobile robots can rapidly increase the speed and efficiency of moving inventory from stock locations to fill customer orders.
Sorting: Sorting and consolidating warehouse inventory is a time-consuming, often confusing task. Automated sortation and AS/RS systems improve inventory accuracy and quality control by recognizing and handling small or fragile inventory separately.
Replenishment: Automated inventory tracking and cycle counting empower automated reorders. When an inventory item reaches a designated par level, the system automatically triggers an order request and flags it for approval. Automated replenishment can help prevent overstocking costs and inventory loss due to spoilage and theft.
Packaging: The packaging stage of order fulfillment is critical due to the high cost and environmental impact of packaging materials. Automated packaging and cartonization systems use algorithms to determine the best type of shipping packaging based on product attributes (like durability), dimensions and material costs.
Shipping: Automated shipping systems uses conveyors, scales, dimension sensors, printers and software applications to determine available carriers, estimate shipping rates and apply labels to packages for shipment.
Real World Examples of Warehouse Automation
The popularity and growth of ecommerce has increased the demand for warehouse automation. Here are some examples of how it works across various industries:

Barcode Scanning: Amazon uses automated barcode scanning and labels to dominate online retail and optimize warehouse operations. This automation is responsible for Amazon’s famously innovative storage system. Unique barcodes are placed on incoming products and on the shelves where they reside. When it’s time to ship a product, employees use the updated picking list to find the product location based on automated routes optimized for efficiency and flow.
Picking Automation with GTP Systems: Nike implemented a GTP picking system in its new distribution center in Japan. The automated GTP picking system uses autonomous robots to carry products and packages loaded on shelves or pallets directly to warehouse workers for order fulfillment. The new warehouse automation helped transform logistics and enable Nike to provide same-day delivery to customers in Japan.
Inventory Automation with AS/RS Systems: IKEA operates highly automated warehouse facilities worldwide. Its distribution centers feature AS/RS inventory automation systems and equipment, including 100-foot-tall trilateral stacker cranes and conveyor rack systems capable of automatically transferring 600 pallets an hour to dispatch areas.
Back-Office Automation: WMS platforms with digital process automation features can optimize back-office operations. iAutomation, a distributor of machine control solutions and services to OEM machine builders, had siloed applications that slowed productivity, as staff had to manually import and export data across multiple systems to support sales and customer service teams. The company implemented NetSuite's Inventory Management, CRM and Manufacturing Execution System to enhance back-office sales and customer support functions with automated barcoding, case management and issue tracking solutions.
