About Onesys

A Brief History

Onesys have been providing successful business solutions since 1972. We have a number of clients that have been with us since our establishment. They are now running the latest versions of our products and have benefited from our client focused approach. Our aim is to ensure that we maintain long-term relationships with our clients. We ensure that their software solutions meet both short and long-term needs. We deliver high quality support and ensure that our clients benefit from a low total cost of ownership from their software investment.

We have successfully supplied and supported software solutions for clients such as Christy Towels, Kavli Foods, The Bank of England and WWT. The metropolitan police uniforms are supplied by a Onesys customer using a Onesys system, the bolts in Jaguar cars are supplied using a onesys system.

We support and deploy systems mainly in the UK but also successfully across the world. Onesys are now a leading supplier of timesheet, project and billing systems in the UK, with thousands of satisfied users.

Onesys is the largest UK partner of Global Business Systems and Sage Professional Services Division. We have also successfully formed partnerships with a number of other key vendors such as Version One, IBM and Microfocus.

Onesys continues to grow organically and through acquisition. Further acquisitions are likely as we seek to consolidate our market position and expand in new directions. Our strategy is to build a strong business with a balance of technical and client service skills, constantly update these skills and then to apply these skills in delivering excellent business solutions to all of our clients. Each acquisition broadens our technical skills and expertise whilst providing deeper resources in key areas such as our user helpdesk and software development. If you would like to discuss how we could possibly release the value of your business or partner with us then please contact us.


It is important for you that our team can provide you with turn-key business management tools. You will find that we have the right combination of experience, skills and flexibility to do just that. Most of our consultants, developers, installers, trainers, support-staff and managers have been with the group for many years and have a thorough knowledge of the products we provide, and the business sectors we serve. Constant staff training and a customer service ethos are our key aims.


All our application solutions are based on open platforms and developed in long term environments enabling the longevity of them all, easy application interaction and a low total cost of ownership.
