I also need to have NO DUE DATE - the Home Owner's Association that I am treasurer for wants to allow on-line payments - these payments may occur at one time or people may spread them over the year - we have people who have large over-due amounts (missed yearly payment) and would like them to be able to pay partial amounts when they can. The problem is this can't be done ON-LINE with Intuit's merchant services. They do not allow on-line payment of over-due invoices.  This seems to be contra-productive. The reason we want to use on-line payment is that it saves paper and makes things simple.

Why is there no way to partial pay on-line - the DUE DATE messes that up.
