The role of finance departments, especially in small-to-mid-size companies, is dramatically changing. Traditionally theirs was a secondary role. They were locked into the tasks of keeping the books, paying the bills, and delivering historical financial information to executives. Moreover, they were bound by the constraints of using burdensome, non-integrated financial systems.
Today, because of the advent of fully integrated systems (some of them cloud-based and some of them on-premise) and their ability to access data from any web-enabled device, even smaller finance departments can stop spending most of their time on such tasks. Based on the unparalleled insights that come from having seamless integration, they can spend more time giving financial-management advice and identifying business opportunities. A CFO can become a strategic corporate asset to the company.
To learn the specifics of how, see the Accounting Web article, How Chief Financial Officers Can Become Major Corporate Players. It identifies advantages of modern ERP systems like Dynamics SL or Dynamics 365 to free up CFOs.
