The employees in my company don’t have the same level of responsibility. I’d like to be able to control who does what. Is this possible?

Exactly. There are user profiles with different levels of access. For example, an employee in charge of drawing up quotations and contracts may not have access to HR information (employees’ personal details) or accounting data (invoicing, receipts, etc.).

You have the power to create and define profiles and access for each of your employees.
