That's what I figured, basically number cost and usage. I just didn't know if items such as E911 would be added to all services or only certain ones, which is why I created the sample in my first post. I just need to make sure I was understanding complete charges as without this understanding, creating customer pricing would be a disaster.

For example, the primary line is self explanatory. But since faxes for resellers are only incoming, is there a charge for an incoming fax, since it is being emailed?

Forwarding numbers are charged twice as an incoming call and outgoing to the forwarded number, correct?

Virtual numbers run off the primary number for minutes, so there's a number charge, but what about E911?

Toll Free numbers, I'm not sure how they are charged.

EFU is only on minutes used.

And last, which services is E911 added to automatically and which ones is it not needed?

I just want to make sure what reseller charges are in complete so I know what to charge customers.
