I'm currently starting a small debt recovery agency which will deal with both services like invoicing and payment tracking but also hard edge debt retrieval and recovery. For this, I'm looking for an online production suite which will provide the following services:
* client sign-up for several service level packages
* debtor and invoice registration for clients with real-time updates about either payments or formal correspondence
* debtor and invoice registration for clients with real-time information about important issues and tasks to-do
* generation of documents to be printed and sent by mail
* archiving of generated/sent documents, or other correspondence.
I have acces to a working website that has most features present but the programming is lousy. It can easily serve as an example though.
