With the recent updates, after someone submits a partial payment on a calendar, invoices are not created; instead, an order is made.

But within the Order Submitted trigger, there is no "Order Status" filter that would have Partially Paid as an option.

Right now, we can not create any automation to send reminders and collect the partially due balance on an order. This would be a huge time saver, similar to how it was with the invoices.
