About Cohesis

Software built in the field, for the field

For more than 25 years we've written and supported software for the UK building and maintenance industry — and we've spent that time learning exactly what makes a repairs operation tick.

Who we are

Experience that shows in every screen

Cohesis has extensive experience creating and implementing applications that produce the results our clients expect. We don't promise software that will run your business; we deliver working solutions that fit your business and its specific processes and needs — flexible, user-friendly and highly reliable.

Through carefully designed software, outstanding support and systems integration, we've helped leading players in the building-maintenance arena increase their competitive edge — making the process of responding to their customers' needs faster, simpler, more productive and more cost-effective.

Dynamic, innovative and customer-centred, our aim is to be the most trusted and recognised provider of work-flow management solutions to the building and maintenance industry in the UK.
