The number of projects is not limited. So it's up to you whether you automize the project through an automatic project template or individual tasks.
Each task can have its own budget and addition of time sheet for invoicing. The same applies to solvers, of whom there may be more and who will cooperate together on the same task. The
321 INTRA tool is designed for just such delegation and collaboration!
For example,
corporate chat or task comments will take care of fast communication between the participants.
