Update due date based on invoice paid date
We need automatically adjustable due date of services/products.
Invoice due date: 01 Jan 2015
Next due date: 31 Jan 2015
Invoice paid: 20 Jan 2015
System not changing Next due date and still is 31 Jan 2015
We need set it to 29 Feb 2015 (or 1 March 2015)
This is very simple and important feature.
I'm very confused this fact, that WHMCS still has no such important things.
Users can't check thousand of transactions and invoice states to adjust due date manually.
