How much does accounting software cost and can you prove the ROI? How many times have you been asked that question but really have no idea how to calculate specific ROI numbers? In his post called “CRM Customization ROI Calculator” Mitch Milam outlines a simple but effective equation to show how to calculate ROI. He is using it to justify that a client needs customization changes in CRM, but the same principle applies to ERP software. And you can perform the 4 steps to analyze your own team – without waiting for a consultant to sit there and watch you work. For example, if you are doing the same tasks repetitively (such as re-keying data from an inventory system into your financial system) then you need to figure out how much it is costing your company and if you would actually save money by upgrading to a system that automates the process.
