Start by identifying the specific pain points that the organization is experiencing with their current process. Examples may include a lengthy onboarding process, low customer satisfaction rates, or high churn rates.
Once you've identified the pain points, highlight how it can help solve these problems (i.e. it can automate the onboarding process, provide a better customer experience etc).
Executives also want to know it will impact the bottom line. Show them the ROI of the software. If you have to create ballpark estimates of the time savings it would provide then that is OK!
It also doesn’t hurt to demo the software during a trial period. This will allow executives to see the benefits in action and ask any questions they may have. It also helps to paint a picture of what life is like NOW vs what it could be.
Also be ready to address any objections or concerns they may have. For example, they may be worried about the cost or the time it will take to implement the software. Have a plan in place to address these concerns and hopefully whoever you purchase the software from can tell you what the expected TTV should be should everyone meet their deadlines.
