Totally OT : Credit Control Software

Given that lots of people here work in IT I figured this would be a
good place to ask.
I need to find some Credit Control software that can do the following:
Ability to import existing accounts with potentially each Invoice
within the Account being at a different stage of collection.
The ability to interface receipts back to 2 different systems , 1 in
detail the other summary financial information.
The ability to view and chase debt via various Groupings – Purchaser ,
Age of Debt , Amount etc and assign these groupings as a workload to
individual users.
The ability to send pre-configured communications to Debtors with a
configurable timeline escalation path e.g. , Letter 1 Letter 2 etc
The ability to scan and store customer communications against an
account as well as the ability to type notes against an account.

In terms of volume it will need to produce 90,000 letters per year for
around 50 million of debt.
Its currently done in 31 individual databases but it really needs
centralising.

Any suggestions?
Cheers
Steve

 

Quite a lot of standard accounting packages contain an aged debtors
analysis with most of the reporting you mentioned.
