Switch from the generic upgrade page when adding a new business to our current personal upgrade page we built in the system with plan descriptions. This will show the business owner what they're getting compared to the upgrade options. They won't upgrade until they know what they just got. Our SDAI plan page shows them everything with descriptions to sell. To take this page to the next level, we add an optional VSL (video sales letter) above the upgrade options to help sell the upgrades when the business owner is at their hottest, because they just made a decision to sign up because they see the value. This is the time to upgrade them - we have their attention.
