# Workflow last action specificity
> Learn how the final action of an Upflow workflow loops at your defined contact delay to keep chasing aged invoices, and how task-type actions behave differently.
When you are setting up your workflow, you decide how many actions you will need to plan: +100 days, +200 days or even +500 days so that you always have an action to be carried out for old invoices.
The last action in your workflow will repeat itself and come up again every X days depending on what you have decided in your workflow settings regarding the minimum contact delay. This will continue until your customer pays their carrying invoice.
Note that if the last action is a Task, it will not disappear from your To Do list if you *ignore* it, when an email or letter would based on your minimum contact delay.
We advise you to pause your customer's collection if you wish for the task to disappear from your list for a certain amount of time.
