By default the Production Value matches the amount of the Work Order total. It is maintained as a separate value in case it needs to be changed for callbacks or other reasons that would require the base commission value to be different from what the customer gets charged.
Note If you add a service through the mobile app, the production value does not get updated in the Work Order. This also includes Work Orders that have a zero amount and that amount is updated by the tech using the mobile app. The Production Value needs to be updated manually in the web browser, if necessary.
