I would like to know how the payment system works due to the users or the minimum would be 5 users in the business version and would have to pay for them being that I will use 1 user?

Hi Ruiz.

I found myself in the same predicament when I wanted to purchase only 2 user licenses. Unfortunately, Wrike requires you to purchase 5 users as a minimum. I am hoping that changes, as I find Wrike invaluable, and know that many more would if they could purchase 1 or 2 licenses as a minimum. 

I have the 5 licenses, but only 2 of us use it actively.
