Dan,
I have a kron job/task automate this everyday at 6:00am.
Let me see if I get this right.... I don't have Viart yet, but I'm considering using it and recurring billing is something I need, as I do it now.
Are you saying that recurring billing in Viart only works by creating a new transaction every cycle, and then billing the customer for that transaction, regardless, if the payment method is PayPal, or Credit Card, or any other?
Does that generate a invoice to the customer every cycle?
I'm not sure I'd like it to work this way, as I don't believe it's best to have an invoice generated every month.
Have you had any problems with it missing a cycle, for example, your CRON task does not run properly?
Thanks,
-Brett
