1How this bill is counted

Every conversation the AI took part in is billed, whatever its outcome: resolved, handed to a person or abandoned. Each billed item is matched to your own conversation log, and each conversation is followed into your ticket system to see what it delivered.

3What the money bought

The conversations on the bill that match your records, by what happened next. "Came back" means the same person opened a ticket about the same type of issue within 7 days.

Outcome	Conversations	Share	Billed
Resolved, and the person did not come back	540	62.9%	$1,080
Resolved, but the person came back	97	11.3%	$194
Handed to a person	129	15.0%	$258
Abandoned or unanswered	92	10.7%	$184

Per-conversation pricing charges for these whatever happened. They are not billing errors; they are why the cost of each resolution that held is higher than the price of one conversation.
