You can turn Runrun.it into a communication channel with your suppliers and/or customers. Registering them, you can use all the information and time spent in your tasks to make futures analysis.
You could be thinking: “my client will see all my company data?” Not necessarily! It is very simple avoid this.
First, you need to register your customer or supplier (Admin > Users), and don’t let them open tasks for anyone. They will just receive tasks.
Then, include a team (Admin > Teams). The leader of this team must be a person who will is in direct contact to supplier/customer. Thus, they will only receive information about tasks related to them.
This new user will be a regular user.
Remember: it is very important to know the difference between the Runrun.it users. Look here!
