Goods-to-Person Systems: How Singapore Warehouses Are Picking Faster With Fewer Steps
In a traditional warehouse, a picker walks to the inventory. In a goods-to-person warehouse, the inventory comes to the picker.
That single shift in approach — from person-to-goods to goods-to-person — is one of the most significant productivity changes available to Singapore businesses operating distribution, fulfilment, or manufacturing support operations.
The numbers are striking. Manual picking typically achieves 50 to 100 picks per hour. Goods-to-person systems routinely deliver 200 to 400 or more picks per hour, with picking accuracy rates of 99.9% or higher compared to the 95% to 98% typical of manual processes.
This guide explains what a goods-to-person system is, the different technologies available, and how Singapore operations of varying sizes can evaluate whether it is the right fit. For a broader overview of warehouse automation technologies, see Goshen’s warehouse automation systems guide.
What Is a Goods-to-Person System?
A goods-to-person (G2P) system is a warehouse picking approach in which automated equipment retrieves inventory and delivers it directly to a stationary operator workstation, eliminating the need for pickers to walk the warehouse floor to locate items.
Rather than a picker navigating aisles to find and retrieve items, the system handles all movement of goods. The picker stays in one place and processes items as they arrive — a fundamentally more efficient workflow, particularly in high-SKU, high-volume environments.
Goods-to-person systems are not a single technology. They encompass several automation approaches — ASRS-based retrieval, autonomous mobile robots, shuttle systems, and conveyor networks — each suited to different operational profiles and investment levels.
Goods-to-Person vs Person-to-Goods: The Key Differences
| Factor | Person-to-Goods (Traditional) | Goods-to-Person (Automated) |
|---|---|---|
| Picker movement | Walks aisles to locate each item | Stationary at workstation |
| Pick rate | 50–100 picks per hour | 200–400+ picks per hour |
| Picking accuracy | 95–98% | 99.9%+ |
| Labour dependency | High — scales headcount with volume | Low — throughput scales via automation |
| Space utilisation | Requires wide aisles for navigation | High-density storage, minimal aisles |
| Error source | Misread labels, wrong location | System-directed — errors rare |
| Worker fatigue | High — significant walking and lifting | Low — stationary ergonomic workstation |
Types of Goods-to-Person Systems
Four main technologies are used to implement goods-to-person picking in Singapore warehouse environments.
1. ASRS-Based Goods-to-Person
The most established G2P approach uses automated storage and retrieval systems (ASRS) — vertical lift modules (VLMs), vertical carousels, or mini-load ASRS — to store inventory in high-density enclosures and deliver individual totes, trays, or bins to an operator workstation on demand.
- Best for: high-SKU operations, pharmaceutical dispensing, electronics, spare parts
- Throughput: typically 125 to 350 tote retrievals per hour per machine
- Space saving: up to 85% reduction in floor footprint versus open racking
- Investment level: moderate to high depending on system size
2. AMR-Based Goods-to-Person
Autonomous mobile robots (AMRs) navigate the warehouse floor and transport inventory pods or shelving units directly to stationary pick stations. Pickers process items from the delivered unit, then the AMR returns it to storage and retrieves the next.
- Best for: e-commerce fulfilment, mixed-SKU operations, rapidly changing product ranges
- Throughput: scales with the number of robots deployed
- Flexibility: system adapts easily to layout or inventory changes without infrastructure modification
- Investment level: scalable — businesses can start small and add robots as volume grows
3. Shuttle Systems
A shuttle system uses small automated vehicles running on rails within multi-level racking to retrieve totes or trays and deliver them to a conveyor that transports them to pick stations. Well-suited to very high-throughput environments with large SKU counts.
- Best for: high-volume distribution centres, cold chain, retail replenishment
- Throughput: very high — well-suited to peak demand environments
- Space utilisation: excellent — dense multi-level racking with minimal aisle space
- Investment level: significant — suited to larger facilities
4. Conveyor-Based Goods-to-Person
In a conveyor-based G2P system, totes or bins are routed from storage areas to pick stations via a network of conveyor belts and sortation equipment. Less flexible than AMR-based systems but highly reliable and cost-effective for facilities with predictable, high-volume flows.
- Best for: fixed-flow fulfilment operations, parcel sortation, food and beverage
- Throughput: high and consistent
- Consideration: layout changes require physical modification to the conveyor network
Is a Goods-to-Person System Right for Your Singapore Operation?
G2P systems deliver the strongest ROI in operations with specific characteristics. The more of the following that apply, the stronger the case for G2P investment.
High order volumes with many SKUs
G2P systems excel when pickers must regularly retrieve from a large number of locations. The more walking a manual system requires, the greater the gain from G2P.
Labour shortage or high wage costs
Singapore’s tight labour market makes reducing headcount dependency in repetitive picking roles a significant financial advantage. G2P maintains or increases throughput with fewer people.
Space constraints
G2P systems — particularly ASRS-based approaches — replace wide picking aisles with high-density automated storage, recovering substantial floor space in Singapore’s expensive industrial property market.
Accuracy requirements
Operations where picking errors result in costly returns, compliance issues, or customer attrition benefit significantly from the 99.9%+ accuracy rates typical of G2P systems.
Growth planning
AMR-based G2P in particular scales by adding robots rather than restructuring the facility — a significant advantage for businesses anticipating volume growth.
The payback period for G2P investments typically ranges from two to five years, driven by labour savings, throughput improvements, and space recovery. In Singapore’s operating environment — with high wages, high industrial rents, and a competitive e-commerce market — the ROI case is often compelling.
Goods-to-Person in Singapore: What Local Businesses Are Doing
Singapore has emerged as one of Southeast Asia’s most active markets for warehouse automation adoption, driven by its role as a regional logistics hub, its tight labour market, and its advanced digital infrastructure.
Major logistics providers operating in Singapore have deployed goods-to-person systems in distribution centres across the island. One example is a 50,000-square-metre Singapore distribution facility using automated G2P picking where an order can be picked, packed, and labelled in as little as 20 minutes from receipt.
For SMEs, the availability of government grant support has made G2P technologies increasingly accessible. Businesses that previously could not justify the capital cost of warehouse automation are now implementing phased G2P solutions — often starting with a single ASRS unit or a small AMR deployment — supported by EDG or PSG funding.

FAQ: Goods-to-Person Systems in Singapore
What does goods-to-person mean in warehouse operations?
Goods-to-person (G2P) refers to a picking approach where automated equipment retrieves inventory and delivers it to a stationary operator workstation — as opposed to traditional person-to-goods picking where warehouse staff walk to the inventory location. G2P dramatically increases pick rates and accuracy by eliminating unnecessary walking and manual searching.
How much faster is goods-to-person picking than manual picking?
Manual warehouse picking typically achieves 50 to 100 picks per hour. Goods-to-person systems deliver 200 to 400 or more picks per hour — a four to eight times improvement — while simultaneously raising accuracy from 95-98% to 99.9% or higher.
Which goods-to-person system is best for a small Singapore warehouse?
For smaller operations with limited floor space, ASRS-based G2P — a vertical lift module or vertical carousel delivering totes to a pick station — is typically the most accessible starting point. AMR-based G2P is also well-suited to smaller operations because it scales incrementally: a business can start with a small AMR fleet and add units as volume grows.
What is the ROI payback period for a G2P system?
Most goods-to-person implementations achieve a payback period of two to five years, driven by labour savings, throughput gains, and space recovery. Singapore’s high wages and industrial property costs generally push payback periods toward the shorter end of that range. Government grant support can reduce upfront investment by up to 50%, further improving ROI.
Can a goods-to-person system integrate with my existing WMS or ERP?
Yes. Modern G2P systems are designed to integrate with warehouse management systems (WMS) and ERP platforms via API. The WMS directs the G2P system — sending retrieval requests as orders are processed — and receives confirmation as totes are delivered and items are picked. This integration is a key part of any G2P implementation and should be confirmed with your vendor before proceeding.
Conclusion
Goods-to-person systems represent one of the most impactful warehouse automation investments a Singapore business can make.
By bringing inventory to the picker rather than the other way around, G2P dramatically increases throughput, reduces errors, and lowers the labour dependency that makes manual picking operations difficult to scale in Singapore’s tight labour market.
Whether you start with a single ASRS unit at a pick station or implement a full AMR-based G2P fleet, the principle is the same: reduce unnecessary movement, increase picking speed, and let your team focus on value-added work rather than walking aisles.
