Long-term partnership with BE-terna

Mytheresa has a long-term relationship with BE-terna and has been using BE-terna Fashion for Dynamics 365 Business Central (former Dynamics NAV) as its ERP system since 2006.

Over time, the company built a strong internal development team and continuously evolved its ERP environment. Today, Mytheresa independently maintains and develops its ERP system, while working with BE-terna as a trusted partner for specialized topics.

Mytheresa had already been using BE-terna POS in its stores. With the upgrade to the latest ERP version, the POS solution also needed to be brought to the same level. BE-terna upgraded BE-terna POS for Dynamics 365 Business Central to ensure seamless ERP and POS integration.

The result is one integrated ERP and POS system with a single source of truth across all business processes. 

Modernizing POS to support a scalable retail environment

The ERP upgrade created a more stable and future ready system landscape and highlighted the limitations of the previous POS setup. Mytheresa aimed to simplify updates, meet compliance requirements, and create a scalable retail platform while preserving its core business processes.

The project ran from October 2025 to March 2026. The focus was on modernizing the existing POS solution and aligning it with the upgraded ERP environment while preserving all business critical workflows.

The project was completed with a smooth and successful go-live, without any impact on store operations. A complete migration of all relevant data, including articles, prices, customer data, receipts, and vouchers, ensured full operational continuity.

Supporting complex luxury retail processes

Mytheresa operates processes that go far beyond standard retail scenarios. The upgraded solution fully supports these requirements.

The stores use a unique printing setup with needle printers and carbon copy paper. BE-terna adapted the POS printing logic to support this setup while maintaining premium receipt standards.

Voucher handling is another critical area. With very high voucher values, Mytheresa uses a proprietary process combining physical vouchers with additional security codes. This process, including historical data, is fully supported in the system.

A central element is the personal shopper model. Customers can take multiple items home before making a purchase decision. The system tracks item location, returns, and purchases at all times, ensuring full transparency. Personal shoppers, as dedicated in-store advisors, use up-to-date customer and CRM information to curate selections and deliver a consistent, highly personalized shopping experience

Real time retail operations with full control and flexibility

Previously, each POS terminal worked with a local database, requiring manual updates and complex synchronization.

With the upgraded BE-terna POS, Mytheresa now operates a fully online POS with a centralized database directly in the ERP system. This eliminates synchronization efforts and ensures all stores work with the same real time data.

Updates are now managed centrally in the ERP system and automatically deployed to all POS terminals within minutes. Previously, each terminal required individual updates taking two to four hours. Today, all systems remain consistently aligned with minimal effort.

This also ensures that ERP and POS always operate on the same version level, simplifying maintenance and reducing operational risk. The unified system further supports easier integration with the webshop and other connected systems.

At the same time, the solution ensures full control over sensitive data. A detailed role and permission model defines access rights and supports audit requirements while maintaining transparency and traceability across all processes. All changes were documented and tested before go live.

The benefits became clear during the renovation of the flagship store. Operations were temporarily relocated, and the POS system was quickly set up using only a browser-based POS, printers, and payment terminals. Business continued without interruption.

For store employees, the transition was straightforward. Because workflows remained familiar, training was completed within one day. The system was quickly adopted, and daily operations continued smoothly.

Integrated ERP and POS for luxury retail

This project shows how BE-terna helps retail companies evolve their systems without disrupting their business.

By upgrading BE-terna Fashion and BE-terna POS, Mytheresa now operates a unified ERP, POS, and CRM environment that delivers real time data, operational efficiency, and a premium customer experience.
