Bespoke Development

Over the years we have developed our own packages and undertaken bespoke development around most of the major ERP systems. If you are looking for extra help with your legacy AS/400 RPG applications then you have come to the right place.

We have worked in a wide range of sectors including retail, construction, oil refineries, insurance companies, motor manufacturers, banks, workwear providers, bailiffs, education and more. 

It doesn’t matter if your current System i system is using legacy or the most up to date techniques – we are happy to develop systems to coexist alongside them. Whether it is a complete development or simply some additional functionality, our team will work with you to ensure we understand what you want to achieve and work closely with you to guarantee the end result meets all of your requirements.

Maintenance and Updates

Does your system need updating? Many businesses are still running on legacy applications but it’s not always the best idea to try and replace it with something entirely new. We’re able to maintain and update your legacy system to ensure it can meet your business needs without having to migrate to an entirely new system which can be costly and fraught with issues.



If you are struggling with finding the right skills to support your systems or would like to retrain your existing staff to newer technologies then we can help. We have worked with third party package solutions and bespoke in house written applications. Our highly experienced team has years of experience in dealing with software and business issues.
