Scope as a data controller

Yes, it is correct, you listed the cases in which your company will act as a data controller. In these cases, in fact, you decide the purpose and means of data processing: the management of the employment relationship, your website, the relationship with your clients, and your suppliers. On the contrary, your app provides a service that other companies (your clients) will use, so all data that you will collect and process through your SaaS will be processed on behalf of your clients, which is the definition of a data processor.

As a data controller, you are responsible for fair, transparent, and correct data processing, you need to provide information about your processing, collect consent and guarantee that data subjects can exercise their rights. You need to comply with all obligations that the GDPR requires the controller to comply with as stated in Article 24 GDPR.
