legacy Point of Sales

Point-of-sale or POS systems have been working great for the last decades, but as computational technology and businesses across industries keep evolving, those solutions can’t meet growing demands in the best way. Today, legacy POS systems require scalability, modern and customizable UI/UX, as well as straightforward, cost-efficient maintenance.

If not timely modernized, point-of-sale software will restrain your growth.

How to handle legacy POS re-engineering

When organizations consider legacy POS modernization, they typically think of:

  • Building products from scratch
  • Or “rip and replace” their desktop POS software

We believe that in many cases your legacy POS system is still perfectly viable and can be upgraded.
To strike the balance, we think bringing legacy POS systems into a digital-ready mode is an iterative process. Sure thing, there’s no one-size-fits-all approach, but, commonly, the key is simply to ensure greater flexibility and resolve existing obstacles to achieve long-term benefits.

Handling legacy POS re-engineering: our approach

Every modernization – platform migration, functionality extension, or migrating legacy mainframes to a modern programming language and integrated development environment – might involve costly pitfalls to remember. We believe any modernization is first and foremost about helping business leaders accelerate performance while streamlining the longevity of their point-of-sale software.

At the initial stages, we perform an in-depth investigation to identify the core business objectives and constraints. We evaluate the parts that have major impact on growth and strategy and measure their limitations.

Next thing, we assess potential approaches by discussing the core business needs and requirements.

And finally, we create and approve our strategy by incorporating both determined business and project goals, where we focus on:

  • Reusing the legacy code (business logic)
  • Separating back-end and front-end
  • Automatic testing
  • Separating integral business objects
  • Introducing an API to-be-used by authorized third parties

VB6 to .NET migration to bring additional value

POS modernization facilitates performance, security, compatibility, and flexibility in the business landscape. Quite often, legacy applications come with VB6 migration, as many business leaders are still using outdated, VB6-based programs, including enterprise-level ERP, CRM, POS, and CSM systems.

As part of strategic POS modernization, many organizations might approach VB to .NET migration to harness modern features, including productivity, security, compatibility, and others.

Visual Basic Version 6 has been a popular programming language and environment in the late 1990s and 2000s. As its mainstream support was stopped in 2008, business leader have been working on converting their applications to newer programming technologies.

VB6 to .NET migration can be quite complex – it involves code rewriting, addressing potential security issues, updating existing third-party dependencies, and ensuring the product meets current regulatory requirements. But despite the challenges, VB6 to .NET conversion can add extra value when approached along modernization, eventually facilitating overall performance.

Why consider VB6 to NET migration?

  • Improved performance across operations
  • Enhanced scalability and flexibility
  • Better security
  • Ensured compatibility with more modern platforms
  • Regulatory compliance
  • Long-term support and maintenance


We help transforming legacy POS software into modern enterprise-level scalable and secure POS solutions that users can use on desktop, web, smartphones and tablets; with an intuitive modern interface, you can learn without extensive training.


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

  • 3rd party integration
    The integration with the client’s POS software, or any other ecommerce platform
  • High scalability
  • Complete Independency
    Independent ecommerce microservices that could be switched on and off without disrupting the operating POS.


The advantages of having microservices for omnichannel POS, following domain-driven design include:

  • A complete microservice independency (during the development and lifetime processes).
  • Different programming languages can be used to write different services (the maximum code reuse as a result).
  • Fault isolation (a fail of one microservices will not cause fails of other services).
  • An easy deployment, scale and integration with third-party services.

Tools and technologies:

  • .Net Core 2.0, Angular 5, Azure Service Fabric, DDD, EDA, HATEOAS, JSON API.
