Project disclosure, license purchase, and date setting

Hello. We are an agency in charge of the brand’s AR event production agency, and we have purchased and are currently using a pro plan. We are going to publish for a brand event that will be held for three months soon.

  1. Is it possible to proceed with the project behind closed doors? We will proceed with the process of executing AR by scanning the QR code.
  2. Is it correct that I need to purchase additional Quarterly commercial licenses to proceed with the brand event?
  3. Can I purchase the license in advance and start the event from the date I want?

Thank you for your reply.
