Been wanting this for years! Great job on getting this module out.

What does the "avoid creating" setting do? Does it keep the system from creating zero $ invoices altogether?

When that setting is selected and I manually create a $0 invoice, I get a WHMCS error page - which is OK - just wondering if that's what's happening?

Module breaks invoices assigned to the order (2 times the same invoice is assigned to 2 different orders).
After ordering for $0 the error "Invalid Invoice ID" is displayed.
