Can I time my work time in Simple CRM and link a production cost to it?

Yes, absolutely.

When you enter an Interaction, you can start a stopwatch.

When you stop it, it will then charge a cost to the work done.

The cost is calculated on the basis of your hourly cost that your Simple CRM administrator / internal manager will have assigned to your user profile from the administration interface.

The average cost of an employee is 28 Euro per hour.
