From fashion retailers to supermarkets, the retail industry is very diverse, but also highly competitive, fast-paced, and full of challenges. And with operating costs continuing to rise and margins under pressure, business owners don’t need added uncertainty about their digital retail solutions capability.

Our client, a Swiss provider of Point-of-Sale and connected commerce solutions plans to provide a suite of independent microservices that could transform any legacy or cloud-based POS system the retailer is using into an omnichannel POS without heavy investments of a full migration.

The retailer can add as many services as they really need (gift cards, loyalty system, product and order management and many more) in a flexible non-disruptive cost-effective way.

About Lime-Tec AG, Swiss Retail Software Provider

Since the foundation in early 1999, Lime-Tec has been developing its software and hardware products with retailers in mind. At every stage of development, their customers participate, so that the products and services are always geared to the real needs of the users.

Supported by industry-leading hardware, networking, and support, Lime-Tec is providing POS software, cashier register, self-checkout, and innovative solutions that support growth for the fashion, footwear, and jewelry store owners.


Since the main idea was to provide a suite of independent microservices for digital retail that could transform any current POS system the retailer is using into an omnichannel retail solution, there were a few challenges that our developers had to resolve:

  • The integration with the client’s POS software, or any other eCommerce platform.
  • High scalability when needed.
  • Complete independence of digital retail solutions that could be switched on and off without disrupting the operating POS.


Due to the fact that there is no formal definition of microservice architecture, we can describe it as the method of developing software systems and applications utilizing independent, small, modular and loosely associated services.  Each microservice is developed and deployed independently which ensures that the failure of one microservices will not cause other services to fail. Different languages can be used to write different services.

After carefully analyzing the project requirements the team decided to go with Domain-Driven Design (DDD). It posed quite a challenge since DDD technical rules and patterns have a steep learning curve, however, it provided a lot of advantages as well.

The advantages of developing microservices for omnichannel POS, following DDD include:

  • Creating a shared common understanding of a complex business domain, which helps with the entire process of digital retail solutions development and support.
  • Development of a “ubiquitous language” based on business domain technical terms that greatly facilitates communication between domain experts, designers, and developers and permeates all the areas of the project development.
  • Using a set of building blocks and patterns to ultimately obtain a well-structured and understandable domain model in the code.
  • DDD is primarily not technical, but about communication and knowledge. The application of DDD is done in very different ways, but there are some well-fitting architectural styles, such as event sourcing or CQRS, which support the DDD concept.

Communication between these independent services that run their own processes is achieved via a lightweight but well-defined mechanism. The software microservices are hosted on the next-generation platform, Microsoft Azure Service Fabric, designed to facilitate the development, deployment, and management of highly scalable and customizable applications for the Microsoft Azure cloud platform.
