Since 1996, Infomill has helped field service organisations access the technical information they need, exactly when and where they need it.

Our deep experience in the field service sector enables us to deliver robust, industry-recognised software and services trusted by customers worldwide.

Our global customer base has included organisations such as ALSTOM, China Light & Power, Arvin Meritor, Atlet (Nissan), Hyundai, BAE Systems, Hitachi, Barloworld Handling, Toyota Industrial Equipment, Rolls-Royce, and Winterhalter.

In January 2023, Infomill was acquired by Vela Industries, becoming part of the wider Constellation Software Group. This provides us with the backing of a global organisation comprising over 1,000 software companies, giving us the strength of long-term financial stability, opportunities for cross-collaboration across the group, and expanded global reach — all of which directly benefit our customers.

Our mission is to deliver software that simplifies how field service organisations manage and use technical information, helping them reduce costs and deliver better service outcomes.
