As your event grows, you may out-grow your current payment plan. Upgrading to a new plan is simple. The Billing tab (in the Event Setup section) is where you can upgrade your plan (Event Owners only).
The Billing tab will show the currently selected plan and which plans are available for upgrade. To upgrade your plan (and enable more features for your event) select your desired plan and follow the onscreen instructions.
Details of Plans, Features and Transaction Fees are at our website.
