In a growing company the person who runs the business, the person who looks after accounts and sign-in, and the person who pays the bill are often three different people. Plankwork gives each exactly the authority the job needs and no more.

Owner: the business side, with sight of every project.
Admin: accounts and sign-in, with no extra view of the work.
Billing: the plan and its payment, with no view of the work either.
Organisation settings, kept in the Owner’s hands.
Acting as another person to see what they see, with a record of it.

The full chapter, with every step and setting, is in the app: open your account menu and select User manual.
