Next-Gen Retail Experience for a leading Consumer Electronics Retailer with SAP Integration Suite

About the Customer

Nordic’s leading consumer electronics retailer operating under multiple brands in Sweden, Denmark and Finland.

The company retails consumer electronics, mobile phones, computers, white goods, domestic appliances and kitchen goods among other products. Additionally, it provides product-related services both directly to consumers and to businesses. As an omnichannel retailer, the company serves its customers through both online channels as well as over 460 brick n’ stores.


The customer managed twelve different legacy systems that could not support the company’s vision for a next-generation retail customer experience. With the existing systems no longer able to accommodate growing requirements, the vision involved building a holistic Next Generation Retail (NGR) program; a digital transformation program that was designed to impact:

  • Customer Experience
  • Efficient Planning
  • Transparency
  • Cost Control


The vision with the program was set out to modernize the IT landscape, functionality and move all of the core business into the cloud. At the heart of this program, was the implementation of core SAP product suites and a robust Integration Solution.

Tarento as the partner of choice

The Retailer’s search for the right partner to help with implementation ended with Tarento.

Tarento brings to bear the experience of solving similar challenges in the Nordics, strong digital transformation capabilities, extensive retail domain experience and deep SAP product expertise positioning them as the ideal partner.

Tarento partnered with the retailer on the transformation journey and helped deliver a Hybrid Integration Platform. The team worked closely with the customer team to deploy a modern integration solution on time to the Nordics Market covering 460 stores, B2B and B2C Webshop.


The revolutionary shifts inherent to the program decision posed several challenges that impacted both the choice of the integration platform as well as the implementation.

  • Some of the platforms including the legacy integration platform that were marked for sunsetting in the customer landscape, were still serving several critical processes.
  • The Next Gen Customer experience needed to support mobility, unified experience across channels, a single customer journey among other needs.
  • The IT landscape went through a transformation by adopting a Cloud-first approach, building Micro-Services, Onboarding to SAP C/4 Hana and moving SAP Workloads to Cloud.


The selected Integration Platform needed to cater various integration styles and patterns. It needed to be resilient, scalable, complement the complex landscape and handle high-volume event-driven requirements.
