Success Story
Peter Hahn
Future-proof technology for fashion retail
Peter Hahn digitalises its ERP landscape with SPH AG and Microsoft.
For more than 60 years, Peter Hahn has stood for exclusive womenswear and, as a multichannel retailer, combines mail order, brick-and-mortar stores and digital sales channels. To meet the growing demands of the industry, Peter Hahn has decided to modernise its IT infrastructure comprehensively.
The existing IT landscape could no longer keep pace with changing business models. A modern, scalable ERP platform was required to streamline processes and position the company for future growth.
Challenge
Over the years, Peter Hahn has developed its own IT solutions, which have increasingly reached their limits due to the dynamic market environment.
- IBM host system with customised extensions
- Fragmented processes and manual workarounds
- Different individual solutions for finance, logistics and sales
- New requirements driven by international expansion and legal regulations
Every year, Peter Hahn processes around three million orders, manages 800,000 items (SKUs) and controls four million customer records. The complexity of the system landscape prevented efficient scalability.
Solution
Following an analysis of the requirements, Peter Hahn opted for a combination of Microsoft Dynamics 365 Finance and Supply Chain Management as well as the SPH industry solutions IN:FASHION and IN:OMNICHANNEL.
Why SPH
The decision fell in favour of SPH AG because of its in-depth knowledge of the specific requirements of the fashion industry. SPH contributes proven best practices for fashion and retail, supplementing Microsoft Dynamics 365 with its own solutions IN:FASHION and IN:OMNICHANNEL. These solutions enable standardised yet flexible processes.
The agile project approach, which ensured close coordination and a high level of responsiveness to new requirements, was also a deciding factor.
Project
approach
Peter Hahn and SPH implemented the ERP project in two closely aligned phases:
Phase 1
Optimisation of financial processes
- Replacement of the existing SAP finance solution
- Introduction of automated intercompany accounting
- More efficient invoicing and controlling processes
Phase 2
Digitalisation of retail and logistics processes
- Introduction of IN:FASHION and IN:OMNICHANNEL
- Integration of the webshop via the Commerce Scale Unit to ensure greater stability and performance
- Improvement of inventory management and optimisation of price control
Due to the Covid-19 pandemic, it was necessary to swiftly transition from the planned on-site workshops to a partially remote project approach. Despite this challenge, the project was successfully implemented thanks to the close collaboration of SPH and the more than 50 internal project participants.

Collaboration
and outlook
Every successful ERP project relies on a strong combination of expertise, communication and trust. The close collaboration between Peter Hahn and SPH was a key success factor throughout all phases of the Microsoft Dynamics 365 implementation. Challenges were identified at an early stage, assessed professionally and resolved jointly, thereby strengthening the project team across all areas.
- Clear communication throughout the entire project
- Specialised industry expertise with proven fashion and retail best practices
- Agile project management ensuring flexibility and transparency
Following the successful implementation of the ERP system, SPH also assumed responsibility for Peter Hahn’s operational IT services. This includes providing ongoing support and further development of the system landscape, day-to-day operational assistance and the continuous optimisation of the deployed applications. Thanks to this seamless transition from implementation to operation, the solution remains not only stable, but continues to evolve in line with business requirements.
With its new, scalable and future-oriented system architecture, Peter Hahn has established a solid foundation to respond flexibly to market developments. The partnership with SPH continues to be a key driver of innovation, enabling continuous process improvement and the delivery of a high-quality shopping experience across all channels.
As a result, the digital modernisation has not only been successfully completed but also provides the basis for the long-term development of IT and business processes at Peter Hahn.
