Why Greycon?

More Paper Mills and Plastic Film plants use Greycon software for planning, scheduling and MES than any other.

Greycon has grown organically by aligning interests with our clients and only providing this type of system.

We are financially conservative and strong with negligible debt. Our Directors and staff own well over 90% of the equity and have a very significant interest in the company. Our growth has been achieved without borrowing and we have robust internal controls and audit procedures.

We practice an incremental improvement process supported by a release cycle 1-2 times a year. Our R&D expenditure is around 25% of our sales. We place tremendous importance on the quality of our software and consider our test suites one of the key intellectual property assets of the company.

We believe in openness and consistently publish and share more information with our prospects and customers than any competitors.

We are genuinely multi-cultural and foster a diversity that allows individuality and creativity to be expressed by our talented people.

We take genuine pride in being flexible in our product portfolio and can develop cost-effectively to address individual needs, always rolling such enhancements into the generic products in due course.

We partner with some of the industry leaders in our sector, including Intel, Microsoft and SAP and are recognised by them in return as valuable contributors to progress.
