Keeping The Classics Running: Our Legacy System Magic

Legacy systems remain hugely important for many businesses despite the surge in modern technologies and cloud computing. There are many reasons why they're still in use, including the high cost of replacement or that they still perform their unique functionality perfectly well.

If your company has decided to stick with its legacy system for the time being, you need reliable support from a trusted legacy system support provider to diagnose and fix any bugs efficiently to minimise disruption to your business.

In 15 years, we have supported many legacy systems on behalf of our clients, resolving their issues and helping them future-proof their systems of yesteryear. There are many reasons why companies come to us for legacy system support, with the most common reasons being:

  1. Their legacy developer has left and they cannot find a developer with the skills or willingness to work with old code
  2. To give time back to their IT teams
  3. Save money on repairs
  4. Business continuity
  5. Minimised disruption
  6. Further development/enhancement work to the system
  7. Want to integrate with other IT systems


Here are some examples of the types of legacy systems we've supported for clients across different sectors:


Microsoft Visual Basic 6.0 Information System

One of our clients, a global waste management company, uses a specially made internal system at their Weighbridge stations for logging weights from Weighbridge Readers for customers bringing waste in. From there, it allows staff to log signatures in the system from a signature pad, print out waste, vehicle and company details and manage customers, contracts, routes, invoices, sites, stock and more. 

Built over 15 years ago, the system has been extensively and continuously developed to meet changing business demands, making sections of the code bulky and more complicated to manage.

Through a managed contract, we support the client with software maintenance so that their operations are minimally affected by any bugs or disruptions to their system.

“Having worked with PSP for two years so far, I can honestly say they are very easy to work with. Responses are quick and accurate, and their work goes above and beyond expectations. I have found Brett and Deborah to be very dedicated and have helped us out of some challenging situations. Thank you!” (Director of IT, 2023)


ERP For Manufacturing Company

A legacy CRM/ERP that a furniture specialist uses to run their production, manage their customers and analyse costs. Initially, our developer worked two days per week with the client to help improve and modernise the existing code. Once the updates were complete, we continued supporting the client through a managed support service, which ran alongside a web development project where we enhanced the functionality of their eCommerce store through Magento.

“Excellent service, great communication at all times and make you feel a valued customer. PSP have developed our bespoke ERP system, can’t fault the quality of their work. Been a great experience doing business with the team at PSP.” (Managing Director, 2022)


Student Management System for Chartered Institute

We’re proud to have partnered with chartered institutes and awarding bodies for the past 14 years, delivering multiple services from bespoke development to IT strategy and management.

For nearly ten years, we have supported one particular chartered institute (providers of the largest globally recognised qualification in their profession) with their student management system. With our experience in taking and managing legacy systems alongside our knowledge of awarding bodies, we provided first-class support for their internal system built on an unsupported .NET framework.

The system is linked to the main website and is where students log in to access course information and their information. Therefore, it must work reliably so students can access their information online. In some cases, solving errors involves liaising with their external IT service supplier directly, which we take over on behalf of the client. 

When they chose PSP to support their legacy system, they said it was because of PSP’s “breadth of technical skills, and a proven track record in providing similar services to another professional association which is also an awarding body.” (Director of Marketing and Business Development)


Let's Talk About Your Legacy System


Does your business rely on an old and unsupported IT system? Are there enough people within the company who understand the ins and outs of your legacy system or is all the knowledge inside just one developer's head? If so, you need to share that knowledge with an external support provider so it is never left unsupported.

Leave your legacy system in the hands of PSP and we'll ensure it continues to operate safely and reliably.

We are also experienced in upgrading legacy systems, whether it's a cloud migration, integrating third-party apps, or giving it a more modern look ad feel. Click to read more about legacy system modernisation.
