I am Working on Service Desk and Software, my client doesn't have JSU - Suite Utilities for Jira, I had a project where i have to work mostly on 27 transitions for 5 statuses where i have to use post-functions, validators, conditions and properties and add separate screens for each transitions. i have to develop script for each. Can i know the N number of JSU uses,how it works and is it one time purchase( i have seen its one time but what is we upgrade jira version) JSU so that i can convince my manager to purchase it
