With Services, you can select from all the services created in the admin area under Templates/Services.
No extra task is created for this service and therefore no times are tracked via the iPad.

Services are not dependent on the number of produced copies, but can be displayed in quantity or time.

Depending on the workflow, you can display and calculate image retouches, plots, proofs, etc. quickly and clearly.

All services specified in the calculation are automatically transferred to the invoice as an extra item.
