I work in a company where we have one computer on the graphics. We want to buy an adobe package for all products on this computer. Which plan to choose? Individual or Business?
It depends on who plans to use it. If it is more than one person then each person needs to be licensed to use it.
it will be used by only graphic designer (one person)
An individual plan will be fine.
Whichever Adobe ID (email address & password) is set up for that person, the License will be tied to that Adobe ID. If that person leaves, the plan cannot be transferred to another Adobe ID. You'd have to start again with a new Adobe ID and a new plan.
