You can amend the services your company offers. The screen is divided into 3 columns.
Navigate to Configuration > Order input
The left side column shows all the possible configuration categories which links to the order input.
If you click on one of the categories in that column, you will see that in the second column, all the options which links to that category are shown.
In the third column, you can now see the details of that option and edit them if necessary.
Options shown in grey (or light green when selected) indicate that that option is inactive. This means that you can't use that option in the orders as of that moment. Previously created orders that you used that options won't be changed.
Below you can find an overview of the categories shown on the order level page. You can click on the links for more information.
