We're a web development agency that's branched out into broader content creation and marketing services. We use Jira, Tempo and Kanban boards to track our clients (Projects) various jobs (Issues) we're doing for them, often on retainer.
How do I create a monthly report to send to clients that shows how much time per Issue we've done for them that month?
As an added complication, some jobs we do for them fall out of the retainer so it's important to be able to deselect some of them for the final report.
Full disclosure, I'm very new to Jira in general and had minimal training for it!
