Sales Commissions can now be calculated either on Won Deals or on Confirmed Quotes.
This is set in the Options menu / Commission tab of the Sales web app. In this screen, you also set the default commission % and a maximum Commission amount. The actual value in dollars of the commission can be overridden in the Edit screen of a specific Deal or Quote. Note that if you change the amount after this, the commission will be recalculated again based on the default rule.
The Commission Report has been updated to display the data either for quotes or deals.
