I am writing an invoicing module for a project where invoices are generated, payments are made on a recurring basis. This requires the generation of an invoice with certain detail lines, which will have a due-date of 10-30 days, and, if payment information is on file currently, on the duedate, the invoice is paid with the existing payment info.
Granted, some of the functionality is already written in the E-Commerce modules, some customization would be needed. Of course I need to write a gateway module to work with my existing credit card gateway providers and also a modification to submit invoices through paypal.
However, ecommerce doesn't really seem to be up to 5.1 standards and doesn't seem to be really close to what I need to do. Some of the foundations are there, however, it appears that ecommerce duplicates user info. I was thinking that using user-preferences would probably be better for storing some of the information in my case.
Am I better off trying to upgrade portions of ecommerce and customize? or is this one of those times where I would be better off writing a package to do what I need?
