Tool to capture, analyse and monitor P2P transactions

Just wondering if there is a tool available to help capture, analyse and monitor my P2P transactions across various platforms?

I am looking for functionality which would include:

- help determine the overall rate of return on one platform and across various platforms

- help monitor defaults and bad debts

- Monitor exposure to a specific borrower for separate loans taken by him


I would be happy to pay a reasonable amount for a flexible tool and would of course welcome any Excel template(s) anyone is willing to share.

I could try and build my own Excel model but wish to avoid reinventing the wheel.
