Azibo supports sole proprietorships, single-owner LLCs and single-member corporations.
I am a property manager, I've created an Azibo account. I manage a number of properties that are owned by other people, as a property manager who owns this account I will have all available features and will be in charge of managing these properties, renters and payments.
I will add the properties that I manage and organize them into portfolios base on their respective property owners. I can then share the portfolio with the owner so they can see these properties, renters and related invoices (learn more about the sharing permissions here).
Since I manage properties for many different people I can share each portfolio with the involved owners. This is the ideal usage of Azibo for property managers.
