Question about Orchestrator/Licensing

Hi, i’m working as a junior rpa developer, the team I work with developed an application for calculating and declaring the monthly tax (VAT). We use UiPath to automatize the ETL process from our clients’ systems and the use of the application itself (attended). We want to make the jump and get an Orchestrator license, my question is the following. If our team get that license can we manage, control and monitor the robots we developed for all our clients, if that’s possible, my second question is: Should we be the ones who purchase all the licenses appart from the Orchestrator and Studio ones? Are there any legal problem in doing that?
Sorry for the question, I don’t even know if it makes senses but I coudn’t find info.
