I was asked about Open Source Billing solutions via email today. It had been a while since I had reviewed this space, but a few minutes in my deli.cio.us network revealed some interesting titles:
- Freeside billing and trouble ticketing (primarily geared towards ISPs)
- CitrusDB (CRM, Customer Care, and Billing for ISPs, Consulting and Telcos)
- JBilling (I'm pleased to see that one is based on the JEE platform)
Al, Scott, I hope you find these products beneficial. Let us know which one you settle with and I'll post your review here.
