[VoiceOps] Recommendation for End User Billing Service

[Mary Lou Carey]

Hello all,

I am looking for some recommendations for an End User billing service. 
Please let me know what companies you have used and what you like or 
dislike about each one. If you don't feel comfortable posting it 
publically, you can e-mail be privately.

Thanks,
