OPUS//G WMS
OPUS//G WMS is a warehouse-management system from a Mid-Market German software house based in Jork near Hamburg. The product is part of the OPUS//SUITE, a modular logistics platform that pairs the WMS with warehouse-control (WCS) and manufacturing-execution (MES) functionality. OPUS//G targets mid-market and large industrial and retail customers with complex intralogistics, particularly recipe-based production (chemicals, pharmaceuticals, cosmetics, food), e-commerce fulfilment, technical wholesale and contract logistics. A distinguishing feature is the integrated 3D visualisation of the warehouse, which is unusual at this segment of the market and useful for warehouse design, planning and operations alike.
Functional scope
OPUS//WMS covers the complete spectrum of a modern warehouse-management system. The core comprises goods receipt, putaway, inventory management, picking, packing and despatch with multiple strategies — chaotic, fixed-bin, class-based, FIFO/LIFO, best-before-driven or batch-driven. Inventory counting, replenishment, returns and yard management round out the operational scope. The 3D visualisation lets operations teams see in real time which areas of the warehouse are heavily utilised, where bottlenecks are forming and how individual orders are progressing through the facility.
WCS and MES integration
The OPUS//SUITE's integration of WMS with WCS (warehouse-control system, driving conveyor and automation hardware) and MES (manufacturing-execution system, driving shop-floor production) is a meaningful architectural advantage. In recipe-based industries the boundary between warehouse and production is fluid — raw material is picked, fed to production, work-in-process is staged back to warehouse, finished goods are picked again — and having one vendor span the data layer reduces interface friction.
Target audience and verticals
OPUS//G WMS addresses mid-market and large industrial and retail customers with complex intralogistics. Focus verticals include recipe-based production (chemicals, pharmaceuticals, cosmetics, food, beverages), e-commerce fulfilment, wholesale, technical wholesale, automotive parts, contract logistics and component distribution. The product fit is strongest for customers running their own warehouse with automation hardware and multiple flow patterns; pure pick-pack-ship operations are typically over-served by the WCS depth.
Technology and deployment
OPUS//G is built on a Microsoft .NET architecture with relational database storage. The platform supports on-premise installations as well as cloud and managed-hosted models, so the deployment can be aligned to the customer's IT strategy. Most installations remain on-premise because of the deep integration with warehouse hardware (conveyors, sorters, automated storage and retrieval systems, scanners), where on-premise infrastructure simplifies the realtime control loop.
DACH compliance and selection
OPUS//G handles GoBD-relevant audit-trail and inventory-traceability requirements through standard inventory history and movement-log features — GoBD being the German principles for proper digital bookkeeping that the WMS must support insofar as it owns inventory data feeding the financial books. Batch and serial traceability are first-class concepts, which matters for recipe-driven industries where regulatory traceability is mandatory. Pricing is project-based with no published list prices, with both perpetual-licence and subscription models available. OPUS//G competes with PSI Wms, viadat, SAP EWM in the larger segment and with specialist mid-market WMS vendors such as proLogistics pL-Store.
Strengths and limitations at a glance
OPUS//G's differentiators cluster around three areas:
- Integrated 3D visualisation of the warehouse, useful both at design and operations stage.
- Single-vendor span across WMS, WCS and MES, which reduces interface friction in recipe-based production.
- Mature German engineering depth, with long-tenured customer references in chemicals, pharmaceuticals and cosmetics.
Limitations buyers typically note:
- The product is a logistics-and-execution platform, not a full ERP — finance, sales and purchasing must live in a separate system of record.
- The depth of WCS integration is overkill for pure pick-pack-ship operations.
- No multi-tenant SaaS — deployments are project-specific, which lengthens initial selection cycles versus a generic cloud WMS.
Best-fit profile and comparable vendors
OPUS//G fits best for mid-market and large industrial customers running their own warehouse with materials-flow hardware, particularly in recipe-driven verticals. Indicative best-fit size is 50 to 500 warehouse users with mixed automation levels. Comparable vendors include pL-Store for technical wholesale, SAP EWM at the upper end, and DACH WMS specialists such as PSI Wms and viadat. Buyers commonly read up on WMS fundamentals and the MES boundary before shortlisting, given how much of the OPUS//G value sits at the seam between warehouse and production.

Frequently Asked Questions
Is OPUS//G a complete ERP system?
No. OPUS//G is a WMS, WCS and MES platform rather than a full ERP. It sits next to the ERP and handles the warehouse, automation and shop-floor execution layer. The ERP remains the system of record for finance, sales and purchasing.
What is the 3D visualisation for?
The 3D visualisation gives operations teams a real-time spatial view of the warehouse: which areas are heavily utilised, where stock-density bottlenecks are forming and how individual orders are progressing through the facility. It is also useful in warehouse-design phases for capacity simulation.
Can OPUS//G run in the cloud?
Yes. Cloud and managed-hosted deployments are supported, but most production installations remain on-premise because of the deep integration with warehouse-control hardware where on-premise infrastructure simplifies the realtime control loop.
Which industries fit OPUS//G best?
Recipe-based industries (chemicals, pharmaceuticals, cosmetics, food and beverage), e-commerce fulfilment, technical wholesale, automotive parts and contract logistics are the typical OPUS//G verticals. Customers running their own warehouse with automation hardware and multiple flow patterns get the most value. Pure pick-pack-ship operations are typically over-served.
