Yes in a creative way. The app does not have a specific field to track or calculate Commission. It is planned for a future version.

You can track commission several ways in the app depending on what fields you use now. There are several fields that add income to your take home. In essence this is what you want to do, even if the field name doesn't say Commission. The following fields add to your Take Home.

The free version of the app will allow you to Track Tips, and Hours. If you don't also track Tips you can just use the Tips field to track your commission.

If you want to track Tips and Commission you'll need to purchase the premium version to enable additional fields.

Once you own the premium subscriptions you can enable Track Cash and Credit Trips from the Settings page. You can use one field for Tips and the other for commissions.

You could also enable Track Tip In and enable Add Tip In to Total Tips so that it adds this to your take home.
