Any ideas on how to create a yearly or monthly invoicing system? I'm looking for a simple invoicing system that I can set the client, payment details, due date, and have it simply repeat yearly or monthly, along with a 30 & 60 day reminder before the due date. Is this possible in any particular module? I tried a couple, but they don't have recurring options, and they all use paypal. I generally use bank transfer (as is done in this country). I don't think I need a full ecommerce system, but if it helps, I'll give it a try as well.
