We process 200,000 e-commerce orders daily, which automated warehousing solution is best?

For e-commerce warehouses processing 200,000 orders daily with over 30,000 SKUs, a four-way shuttle ASRS (Automated Storage and Retrieval System) combined with Goods-to-Person (GTP) picking and  automated sorting systems  is typically the mainstream choice. This approach balances storage density, throughput capacity, and return on investment (ROI).

1.verify operational data

Selecting an automation solution requires looking beyond just order volume; factors such as SKU count, warehouse footprint, order composition, and peak demand must also be considered.

We recommend confirming the following data before planning:

*   Average daily order volume: 200,000 orders
*   Peak order volume: Over 600,000 orders
*   SKU count: 30,000–50,000
*   Average items per order: 2–3 items
*   Warehouse area: 30,000–50,000 square meters
*   Delivery turnaround: Within 24 hours

These figures directly influence the selection of storage systems, picking systems, and sorting equipment.

 2.Four-way shuttle ASRS is ideal for high-SKU e-commerce warehouses

When the SKU count exceeds 20,000, a four-way shuttle ASRS typically offers superior space utilization compared to traditional racking systems.

Typical configurations include:

*   Four-way shuttle system
*   Bin-based ASRS
*   Conveyor system
*   WMS/WCS software

This solution allows for vertical space utilization of 12–24 meters, typically increasing storage density by 30% to 50% compared to standard racking.

3. Goods-to-Person systems are suitable for high-frequency order processing

For e-commerce warehouses processing over 100,000 orders daily, Goods-to-Person picking systems effectively reduce the walking distance required by manual pickers.

Typical configurations include:

*   Picking workstations
*   Tote/bin conveyor system
*   Intelligent task scheduling system

A single workstation typically handles 300–600 orders per hour, depending on order composition and product types. 

4.AutoStore: Suitable for Storing Small Items

AutoStore is a viable option if the inventory consists primarily of small items such as cosmetics, pharmaceuticals, or 3C accessories.

Ideal conditions:

* SKU count exceeds 50,000
* Small product dimensions
* Limited warehouse space

AutoStore typically achieves storage densities 2 to 4 times higher than traditional racking, though the initial investment cost is generally higher than that of standard bin-based ASRS systems.

5. AMR Solutions: Suitable for Rapidly Scaling Projects

AMR "goods-to-person" systems offer excellent scalability for businesses experiencing rapid growth.

Key characteristics:

* Deployment timeframe: 3–6 months
* Robot fleet size can be increased incrementally
* Minimal requirements for warehouse structural modifications

For projects exceeding 200,000 orders per day, AMRs are typically used in conjunction with conveyor systems or automated storage systems.

6. Outbound Sorting Systems Determine Overall Throughput

In large-scale e-commerce warehouses, the outbound process often dictates final shipping capacity.

Common configurations include:
 DWS Systems Used for: Barcode scanning, Weight verification, Volumetric measurement, A single dynamic DWS unit typically handles 3,000–8,000 items per hour.
 Cross-Belt Sorters Suitable for high-volume order processing.

Typical capabilities:

* 10,000–30,000 items per hour
* 100–500 sorting destinations (chutes)

Cross-belt sorting systems are a common choice for warehouses handling a volume of 200,000 orders per day. 

7.Recommended System Architecture

For a typical e-commerce fulfillment center, the following workflow is recommended:

Receiving - DWS (Dimensioning, Weighing, and Scanning) - Four-Way Shuttle ASRS - Goods-to-Person Picking - Conveyor System - Automatic Packing - DWS Verification - Cross-Belt Sorter - Outbound Dock

This architecture is typically suitable for operations with:

*   Daily order volume exceeding 200,000 orders
*   Over 30,000 SKUs
*   Small-to-medium-sized items accounting for more than 70% of the inventory

FAQS

How much floor space is required for an e-commerce warehouse handling 200,000 orders?

Typically, 30,000 to 50,000 square meters are required, depending on the number of SKUs, inventory turnover rate, and the level of automation.

 What is the approximate investment for an automated warehouse project?

Investments for medium-to-large e-commerce automation projects usually range from $5 million to $50 million, depending on equipment configuration and project scale.

How long does it take to launch an automated warehouse?

AMR projects generally take 3 to 6 months, while ASRS and full-warehouse automation projects typically require 8 to 18 months.

How much can an automated warehouse reduce labor requirements?

Most projects can reduce warehouse operational staff by 30% to 70%, depending on the scope of automation.

How should I choose between a four-way shuttle system and AutoStore?

Four-way shuttle systems are more common when there is a large number of SKUs that include medium-sized items; AutoStore is more suitable when the inventory consists primarily of small items and space is limited.
