JMO Systems

Founded in 1988 by John Oliveira, JMO Business Systems Ltd has come a long way from its beginnings in Toronto, ON. JMO Systems originally started as a software consulting company customizing clients ERP systems to meet their unique business needs. In 1996, JMO was contracted by an automotive distributor to write a bolt-on Warehouse Management System (WMS) to integrate with their legacy ERP system. The product was a huge success which inspired JMO to create indago™ WMS and has ever since been focused on delivering top notch WMS solutions. With over 20 years of WMS experience, JMO has become a leader in end to end inventory solutions for many clients across different verticals. We now serve customers all over North America and Bermuda.
