There are two great ways a video can prove your value. First, by explaining some of the specific differentiators, it can illustrate some ways that a company can reap the rewards of switching to SaaS. Things like no upfront investments, scalability, better security, and easier management. While you might not want to go through the whole laundry list, you can definitely touch on your main benefits. The second is that you can show an actual case study. Did a particular company switch to you and save millions? Explain how in a video. Nothing erases doubt like a real-world example.
