Workflow Automation

Workflow Automation

I would to have Zoho Invoice send an email (reminder) when I have a land lease payment due, based on Recurring Expenses "Next Expense Date".  

I am trying to accomplish this by creating a Workflow Automation rule.  The problem that I am having is I don't have a trigger for this action.  I am currently only able to do the following:

  • Execute the workflow when "Recurring Expense" is created, edited, created or edited, deleted.  I chose Created.
  • I need a trigger filtered by "Next Expense Date" so that it will send a reminder when this date occurs.   For example, <When>  <Next Expense Date>  <is>  <today> 

Any help is appreciated.
