It would be useful to have the account value linked to an idea that's generated from the account page, similar to how it's currently done for opportunities.
A new revenue insight is now available on ideas. To get started, first add the new revenue field to your organization custom field layout. Then update your Salesforce integration (or other process) to use this field to capture how much each organization spends with your company. Ideas will automatically calculate the total revenue for all the customers who voted for the idea. This is available with Ideas Advanced.
