Invoice manager I can install on my server

Hey,

I am looking for a script that is an invoice manager.

There are a lot of full blown scripts but they just do too much.

I want something simple thats used to bill clients (Advertisers for me) and let them view, print and pay their invoice online.

Exactly like www.BlinkSale.com but something I can put on my own server.

Thanks!
John
