In his first three years as CEO of Infor, Phillips grew the company significantly through numerous strategic acquisitions, created an in-house design agency to improve software user interface and visual appeal, and updated and upgraded software to better meet niche-industry needs. In 2014, he led Infor to become the first industry cloud company – the first ERP vendor in the cloud offering complete software products for businesses and unique sub-industries – and by 2018 Infor was also the first ERP provider to make a complete transition to the cloud, with the majority of its customers, applications, and revenues cloud-based. In August 2019 he stepped down as CEO to "focus on strategy development, customer relationships, and new acquisitions", as Infor's Chairman.
